This work builds a metamaterial (MTM) superstrate loaded on a patch of microstrip antenna for wireless communications. The MTM superstrate is made up of four G-shaped resonators on FR-4 substrate with a relative permittivity of 4.4 and has a total area of (8×16) mm2, and is higher than the patch. The MTM superstrate increases antenna gain while also raising the input reflection coefficient. When it is 9 mm above the patch, the gain increased from 3.28 dB to 6.02 dB, and when it is 7 mm above the patch, the input reflection coefficient was enhanced from -31.217 dB to -45.8 dB. When the MTM superstrate loaded antenna was compared to the traditional unloaded antenna, it was discovered that metamaterials have a lot of potential for improving antenna performance.

A novel butterfly-shaped patch antenna for wireless communication is introduced in this paper. The antenna is designed for wideband wireless communications and radio-frequency identification (RFID) systems. Two symmetrical quasi-circular arms and two symmetrical round holes are incorporated into the patch of a microstrip antenna to expand its bandwidth. The diameter and position of the circular slots are optimized to achieve a wide bandwidth. The validity of the design concept is demonstrated by means of a prototype having a bandwidth of about 40.1%. The return loss of the butterfly-shaped antenna is greater than 10 dB between 4.15 and 6.36 GHz. The antenna can serve simultaneously most of the modern wireless communication standards.

Abstract Novel and miniaturized hexagonal Microstrip patch antenna design is presented in this paper. Patch is fractured using Sierpinski and Koch structures to make the antenna applicable for multiband applications. Additionally ground is defected to enhance the bandwidth and further size is reduced. Material FR-4 (εr = 4.4)has been chosen to design proposed antenna and substrate thickness as 1.59 mm. Microstrip feed technique is used as it provides better results. Gain obtained in this case is 5.57 dB, 7.49 dB and 4.02 dB with bandwidth as 606.8 MHz, 507 MHz and 2 GHz at 8.3 GHz, 12.6 GHz and 17.6 GHz resonant frequencies. The antenna is better to other designs in terms of parameters like bandwidth, directivity, polarization, gain, return loss and dimension. The antenna provides application for military appliances. A good concord is obtained in Simulated and measured results.

In this work, a broadband high gain frequency selective surface (FSS)-based microstrip patch antenna is proposed. The dimensions of the microstrip antenna and proposed FSS are [Formula: see text] and [Formula: see text]. A broadband high gain reference antenna has been selected to improve antenna performance. The reference antenna offers 1.2[Formula: see text]GHz bandwidth with 6.03[Formula: see text]dBi peak gain. Some modifications have been done on the patch and ground plane to enhance the bandwidth and gain. The impedance bandwidth of 7.70[Formula: see text]GHz (3.42–11.12[Formula: see text]GHz) with 4.9 dBi peak gain is achieved by the microstrip antenna without FSS. The antenna performance is improved by using FSS beneath the antenna structure. The maximum impedance bandwidth of 7.70[Formula: see text]GHz (3.32–11.02[Formula: see text]GHz) and peak gain of 8.6[Formula: see text]dBi are achieved by the proposed antenna with FSS. Maximum co- and cross-polarization differences are 21[Formula: see text]dB. The simulation and measurement have been done using Ansoft Designer software and vector network analyzer. The measured results are in good parity with the simulated one.

Rectangular Microstrip Patch Antenna

This paper presents the design and simulation of a rectangular microstrip patch antenna with enhanced results. Antennas are playing the most important key role in wireless communication systems and especially microstrip patch antenna is the simplest and best form for mobile communication systems. Therefore, the design of antenna for mobile satellite communication and space to earth communication is described in this proposed work. The working of rectangular micro strip patch antenna is studied and the effect of height of the substrate on antenna performance is analyzed and the results are plotted. It has been noticed that the height of substrate should be neither small nor large. The effect of inserting a slot in the patch is also observed in this paper. Return Loss results are plotted for the designed structure and it is noticed that return loss is almost doubled by inserting a slot. Further two symmetrical slots are inserted in the patch and the respective results are plotted. Insertion of two slots gave multiple operating frequencies to the antenna with a compromise of s11. The simulation of proposed structures of antennas is done using ANSYS HFSS (high-frequency structure simulator) which is commercially used as a finite element method solver for electromagnetic structures. A sphere with human brain characteristics is created and average SAR (specific absorption ratio) is plotted on the head model. The proposed antenna has enhanced return loss of -52dB and VSWR of 1.005 at 2.24GHz. This work also introduces multiple operating frequencies using two slots of same size.

Microstrip Patch

A microstrip patch antenna is designed for a wearable antenna. The performance of microstrip patch antenna loaded with reactive impedance surface (RIS) is described in terms of gain, bandwidth and return loss. The antenna is investigated in two conditions which are conventional microstrip antenna with RIS and without RIS. The designed antenna is also aimed at size reduction therefore it will be suitable for a wearable application. This antenna which is made fully using textile and it is designed for operation in the 2.45 GHz band. The performance of microstrip patch antenna loaded with RIS is described in terms of gain, bandwidth, return loss and radiation pattern. The antenna designed with RIS operates at 2.45 GHz. Bandwidth enhancement is achieved with RIS where the designed antenna can cater frequency from 2.4 GHz to 3 GHz. A gain enhancement is achieved of 20% is achieved compared with the conventional patch antenna. Although the size of the patch is reduced with the introduction of RIS, the overall size of the antenna with the substrate is almost similar to the conventional patch antenna. However, the performance of the antenna is greatly enhanced with the use of RIS.

Microstrip Patch

In recent times rectangular patch antenna design has become the most innovative and popular subject due to its advantages, such as being lightweight, conformal, ease to fabricate, low cost and small size. In this paper design of aperture coupled microstrip patch antenna (MSA) on high index semiconductor material coupled with micromachining technique for performance enhancement is discussed. The performance in terms of return loss bandwidth, gain, cross-polarization and antenna efficiency is compared with standard aperture coupled antenna. Micromachining underneath of the patch helps in to reduce the effective dielectric constant, which is desirable for the radiation characteristics of the patch antenna. Improvement 36 percent and 18 percent in return loss bandwidth and gain respectively achieved using micromachined aperture coupled feed patch, which is due to the reduction in losses, suppression of surface waves and substrate modes. In this article along with design, fabrication aspects on Si substrate using MEMS process also discussed. Presented antenna design is proposed antenna can be useful in smart antenna arrays suitable in satellite, radar communication applications. Two topologies at X-band are fabricated and comparison between aperture coupled and micromachined aperture coupled are presented.
