This paper presents an indigenous low-cost metamaterial embedded wearable rectangular microstrip patch antenna using polyester substrate for IEEE 802.11a WLAN applications. The proposed antenna resonates at 5.10 GHz with a bandwidth and gain of 97 MHz and 4.92 dBi, respectively. The electrical size of this antenna is0.254λ×0.5λ. The slots are cut in rectangular patch to reduce the bending effect. This leads to mismatch the impedance at WLAN frequency band; hence, a metamaterial square SRR is embedded inside the slot. A prototype antenna has been fabricated and tested, and the measured results are presented in this paper. The simulated and measured results of the proposed antenna are found to be in good agreement. The bending effect on the performance of this antenna is experimentally verified.

Rectangular Microstrip Patch Antenna

This paper presents a new compact rectangular microstrip patch antenna with a superstrate element. This antenna operates at 2.4 GHz TM01 fundamental mode, which is suitable for WLAN applications. The patch area is reduced by 50% by placing three rectangular slots on the ground plane. In order to compensate for the decreased gain due to the size reduction, a high permittivity superstrate is used with 4mm thickness and 5mm height from the antenna surface. The proposed antenna offers the advantage of occupying half the area of the non-modified rectangular patch while it possesses the same broadside gain of 6-7dB. The trade-off is the additional antenna height due to the placement of the superstrate element.

Antenna Performance

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.

Rectangular Microstrip Patch Antenna

Communication applications require wide band and highly directive planner antennas. For such requirement this work deals with the analysis and simulation of a rectangular microstrip patch antenna loaded with INTERCONNECTED SRR metamaterial structure at a height of 3.2mm from the ground plane. The work also investigates the potential properties of the proposed metamaterial structure. The proposed Antenna is designed at a operating frequency of 2.75GHz to meet S-Band (2-4GHz) applications. By loading Interconnected SRR metamaterial structure with the rectangular patch antenna at a height of 3.2mm, the antennas bandwidth is found to be increased up to 378MHz and return loss is reduced to -42.2dB i.e. the potential properties like return loss, bandwidth, directivity and total efficiency of the proposed antenna increases to a great extent in comparison to the rectangular patch antenna alone. Double Negative properties of metamaterial have been proved by Nicolson-Ross-weir (NRW) method.

Physical Dimensions

This paper presents a new design of the microstrip patch antenna operated at the terahertz frequencies (700-850 GHz). The conventional microstrip patch antenna dimensions shrink to a few microns when operating at such terahertz frequencies. Thus, the design of the patch and its feeding network will be miniaturized extremely, and their fabrications would be extremely difficult. In this paper, the configuration of the proposed microstrip patch antenna is suited in a way that it can be modeled using multilayers structure. This multilayer structure facilitates the modeling, and considering its fabrication. The proposed microstrip antenna has been designed using three layers. The top layer is used to model the rectangular patch; while the second layer is for the substrate, and the bottom layer is for the ground plane.   The physical dimensions of the layers and the fed-line are optimised using the microwave Computer Simulation Technology (CST) simulator in order to enhance the electrical parameters of the antenna such as antenna realised gain, bandwidth, total and radiation efficiencies, and radiation patterns. In addition to that, the impact of the physical dimensions of the rectangular patch on controlling the resonant frequency of the dominant mode (TM01) have been investigated. Keeping the lower and higher propagating modes out of the frequency band of interest is another aspect which has been addressed in this paper. The antenna has been simulated, and its realised gain fluctuates from 6.4 dBi to 9.7 dBi over the operating frequency range (700-850 GHz). Also, it provides extremely large reflection coefficient bandwidth (S11) which it is below -10 dB over the entire operating frequency band. The total efficiency is more than 75 %. Due to its simplicity and providing large bandwidth, the proposed antenna could be of interest in many security and surveillance applications.

In this paper, a dual-band generation in rectangular microstrip patch antenna (RMPA) using a superstrate metal ring has been proposed. In this configuration, a metal ring is placed above the rectangular patch with the support of two dielectric posts. The metal ring behaves as a superstrate layer and resonator for the lower band, the other band is generated by microstrip patch and hence the combined configuration metal ring and patch gives dual-band characteristics. The lower band resonates at 9 GHz with an impedance bandwidth of 6.8% and higher band at 11.35 GHz with impedance bandwidth of 3.1%. The co-polarized peak gain values at these frequencies are 8.2 dBi and 10.1 dBi respectively. This may be used in applications like airborne and naval-radar. The prototypes are fabricated using commercially available dielectric substrate (RT-Duriod r = 2.2 and thickness h =1.6 mm). The measured results show good agreement with the simulated predictions.
