In the last few decades, the development of wireless and mobile communication has influenced social and economic development. Billions of devices demand wireless connection which runs on data, voice and other applications. The antenna is an integral part of any wireless communication system. From the design perspective, the antenna must be compact, easy to manufacture, and cost-effective. This paper presents a design of a rectangular patch antenna, operating at 2.4GHz. The antenna is initially simulated on CST, required parametric sweep is carried out in terms of length and width of the patch, to resonate at 2.4GHz. The simulated antenna is then printed using a PCB printing machine, PCB Prototyping System, Eleven Lab. The printed antenna was tested using Keysight’s PNA-LN-5232A (Vector Network Analyzer). The measurements/ variation in the reflection coefficient were observed /noted within the vicinity of the human body and gold metal plus the human body, at different positions. Near the ear. The simulation results and measured results are in a good match. The designed antenna is suitable for the Wi-fi, WLAN, communication application.

This paper reports the SAR analysis performed to study the effects of the human body on the radiation parameters of a microstrip patch antenna designed on a Roger RT5880 substrate with a relative permittivity of 2.2. The CST Microwave Studio suite environment was used for design simulations, and the antenna was fabricated using MITS electronics’ Eleven Lab antenna printing machine. The printed antenna was placed near the human body to assess its performance in terms of return loss, bandwidth, realized gain, directivity, efficiency, and SAR. The SAR observed in the vicinity of the human body is within the IEEE standard. The designed antenna is hence proposed to be suitable for Wireless Body Area Networks (WBANs) applications.


In this paper, a metamaterial based compact multiband rectangular microstrip patch antenna is proposed. The return loss of metamaterial loaded microstrip patch antenna obtained at the resonant frequency 2.4GHz. The metamaterial structure printed on FR4 substrate at hight of 1.6mm from the ground plane. The FR4 substrate has 4.4 dielectric constant.These metamterial structures are periodic in nature and possesses negative permittivity and negative permeability. The greatest advantage of metamaterial loading will be miniaturization. This metamterial loaded rectangular patch antenna is simulated and tested using HFSS Simulator, where an electromagnetic analysis tool is used. The fabricated antennas results are measured using Vector Network Analyzer (VNA).

The microstrip patch antenna is used in various communication applications including cellular phones, satellites, missiles, and radars, due to its several attractive features such as small size and weight, low cost, and easy fabrication. The microstrip patch antenna consists of a top radiating patch, a bottom ground plane, and a dielectric substrate in between. The patch can have different shapes, the rectangular patch being the most commonly used. In practice, the microstrip antenna suffers from narrow bandwidth and low gain efficiency. This paper aims to enhance the bandwidth and efficiency of a rectangular-patch antenna using the High-Frequency Structure Simulator (HFSS). Initially different patch sizes and substrate materials are investigated and optimal antenna parameters are achieved. Then, the antenna performance is further enhanced by inserting single and double slot designs into the patch. Two cost-effective feeding methods are involved in the investigation. The antenna is designed to operate in the Super High Frequency (SHF) band.

The main aim of this work is to design a compact Rectangular shaped Multislot patch antenna for Ultra Wide Band (UWB) and X band applications. The proposed antenna has a condensed size of 35*30*1.6mm3 . The antenna consists of a rectangular patch with microstrip line feed etched on FR4-epoxy substrate with dielectric constant of 4.4. To improve the bandwidth, circular slots are made in patch and the ground plane. The proposed antenna achieves wide bandwidth of 12.7GHz (3.3-16 GHz) having four resonance frequency with good return loss and maximum gain of 9.64dBi. The antenna is designed, simulated and analyzed by using HFSS (High Frequency Structural Simulator). The charisma of this design is that it employs single patch that makes it easy to fabricate and cost-effective as well.
