In this proposed design a Rectangular E shaped micro-strip patch antenna is present with rectangular and circular slot within the Rectangular patch which operate at frequency 2.4 GHz. By proposed antenna design and coaxial feeding at suitable place  the resultant return loss, VSWR and bandwidth will be find out. For the propose microstrip antenna we have use FR-4 substrate which contain permittivity of 4.4 and thickness 1.5, loss tangent is 0.02. HFSS simulation software is used for designing and analysis.

Microstrip Patch

Easy fabrications and low cost makes microstrip patch radiators more necessary for many applications. In this paper, some observations are made on microstrip patch mounted on a cylindrical curved surface with variation in radius. Considered patch antenna placed on a planar surface operating at a frequency of 5GHz. The same patch was placed on a cylindrical surface with radius of 15mm and 20mm and different properties of the antenna are measured. Here the cylinder will act as substrate and the material used for Substrate is FR4_epoxy with relative permittivity 4.4 and Dielectric loss tangent of 0.02. The antenna design and simulations are carried by High Frequency Structural Simulation (HFSS) tool

In this work, we present a rigorous full-wave eigenanalysis for the study of nanoantennas operating at both terahertz (THz) (0.1–10 THz), and infrared/optical (10–750 THz) frequency spectrums. The key idea behind this effort is to reveal the physical characteristics of nanoantennas such that we can transfer and apply the state-of-the-art antenna design methodologies from microwaves to terahertz and optics. Extensive attention is given to penetration depth in metals to reveal whether the surface currents are sufficient for the correct characterization of nanoantennas, or the involvement of volume currents is needed. As we show with our analysis, the penetration depth constantly reduces until the region of 200 THz; beyond this point, it shoots up, requiring volume currents for the exact characterization of the corresponding radiating structures. The cases of a terahertz rectangular patch antenna and a plasmonic nanoantenna are modeled, showing in each case the need of surface and volume currents, respectively, for the antenna’s efficient characterization.

Dual Band Antenna

A simple and successful dual band patch linear polarized rectangular antenna design is presented. The dual band antenna is designed etching a complementary rectangular split-ring resonator in the patch of a conventional rectangular patch antenna. Furthermore, a parametric study shows the influence of the location of the CSRR particle on the radiation characteristics of the dual band antenna. Going further, a miniaturization of the conventional rectangular patch antenna and an enhancement of the complementary split-ring resonator resonance gain versus the location of the CSRR on the patch are achieved. The dual band antenna design has been made feasible due to the quasistatic resonance property of the complementary split-ring resonators. The simulated results are compared with measured data and good agreement is reported.

Simulation Results

Wireless Fidelity (Wi-Fi) is the modern telecommunication technology nowadays being so widely used and developed at operating frequency of 2.4 GHz, that needs microstrip antenna as best suited supporting means for transmitting and receiving data signals as well at its wave transceiver subsystem.  The proposed antenna design were consists of four elements rectangular patch antenna with peripheral slits technique arranged in a linear array of 2x2 operating at the frequency of 2.4 GHz until 2.5 GHz. In addition to that, the feeding technique used in this research is microstrip fed line. The simulation from this research resulted in reducing the size of related antenna dimension up to 17% compared to that of four elements array without peripheral slits. It is also apparent that the bandwidth of the proposed antenna is 320 MHz (2.253 GHz–2.573 GHz) which is equivalent to bandwidth increase percentage of 13.07%, The simulation results in the center of frequency 2.448 GHz obtained return loss of -26.14 dB with a VSWR of 1.104. The measurement results obtained bandwidth of the proposed antenna is 150 MHz (2.424 GHz–2.574 GHz) which is equivalent to 12% increase of bandwidth percentage. The results of measurements process at the center of frequency 2.448 GHz obtained value of return loss of -16.88 dB with  VSWR of 1.304.

A compact rectangular MS antenna for Ultra Wide Band applications is designed. In the proposed design the rectangular patch antenna designed with cutting a slot in ground of length and width 2.5mm and 3.0mm respectively at the back of feed line. By using the defective ground plane a wide BWof 9.782 GHz with frequency band 3.099 GHz to 12.278 GHz is achieved. The designed antenna with a compressed size of 30 mm x 30 mm is fabricated and tested. The antenna’s return loss and VSWR plots are presented here to confirm the complete UWB bands. Special configuration of patch antenna with slotted partial ground was designed and optimized using CST Microwave Studio.
