In this paper, simulation and optimization analysis on circular patch antenna for 2.4GHz is presented. The performance that been specifically focused in this analysis is the improvement of the directivity and gain of the circular patch antenna design. Basically, the objective of this analysis is to compare the circular patch antenna of a single form with 1x2 antenna array formation. These antennas are designed with the proximity feeding technique. From the previous literature and findings, the optimization works of array arrangement have been proven will improve the directivity and gain performances. In this study, the array arrangement with proximity feeding technique of optimization work to improve the directivity and gain of a circular patch antenna has been explored. Comparison of a single and array of micro strip circular patch with proximity feeding technique as the FR-4 is the substrates with permittivity equal to 3.95 is presented. Based on the results, 1x2 array arrangements enhance the directivity and gain output compared to a single form circular patch antenna design. The directivity performance improves 28% and gain has been improved by 47% after optimization. The findings show that the array elements with proximity feeding technique design offer to improve and enhance the directivity and gain performances of an antenna.

Circular Patch Antenna

Inefficient utilization of licensed spectrum bands and overcrowding of unlicensed bands are caused due to the spectrum shortage and growing demand for wireless communication. The wireless spectrum is burdened due to the host centric traditional approaches for data detection and recovery in the IP-based networks that. The service or data is retrieved from the service provider through a new routing path every time the mobile service requester initiates a request. The vacant licensed channels are utilized appropriately enabling opportunistic and efficient band usage of the spectrum using Cognitive Radio (CR) technology. Wireless communication with low cost, compact antenna element, high gain, wideband and low profile can be performed using patch antenna. Patch is a significant aspect of antenna design. The antenna design parameters are understood by varying the patch. A good return loss can be achieved by enhancing the radiation pattern on changing the patch dimensions. High Frequency Structure Simulator (HFSS) is used for simulation and analysis of the circular patch antenna. The return loss, radiation efficiency, Voltage Standing Wave Ratio (VSWR) and radiation pattern of the antenna are analyzed.

This paper presents a simulation and analysis of a circular patch antenna with different feeding techniques. The objectives of this analysis are to design the microstrip circular patch antennas using five types of feedings techniques which are stepped feed, inset feed, coaxial feed, aperture coupled feed, and proximity feed, to analyze and compares the performance of the antenna design. Performance characteristics of the antenna such as return loss S11 parameter <-10dB, directivity, gain, bandwidth, side lobe level, beam width, and voltage standing wave ratio (VSWR)  parameters of each of the feeding methods designs are obtained and compared.

In this paper, Ultra wideband planar circular patch and half circular ring patch antennas are proposed. These newly simulated structures are proposed for fabrication. The antennas are suitable for operating frequency of 7.5 GHz. It is shown that return loss of the both the antennas at 7.5 GHz is better than -10 dB. The VSWR obtained is less than 2. The half ring patch antenna is found to have the compact size and more bandwidth as that of circular patch antenna. HFSS11 is used for the simulation. From HFSS11 simulations, dimensions of antennas are chosen for better performance. Details of the proposed antenna design and measured results are presented in this paper

Novel Design

Novel design of a dual band microstrip circular patch antenna loaded with ENG (εnegative) metamaterial has been shown in the first section. Using ENG metamaterial instead of the conventional dielectric, unconventional TMδ10(1<δ<2) mode was produced to yield a dual band performance. Optimized parameters such as permittivity (ε1) and filling ratio (η) of metamaterials were selected with the aid of a MATLAB based parameter optimization algorithm, developed for all these sort of patch antennas. In the second section, a dual band circular patch antenna loaded with MNG (µ negative) metamaterial has been reported. An unconventional modified TMδ10(0<δ<1) mode has been produced along with conventional TM110mode due to using MNG metamaterial. Here also the optimum values of permeability (µ1) and filling ratio (η) for these sorts of patch antennas have been calculated from a MATLAB based parameter optimization algorithm. Both the proposed antennas provide good and resonance and satisfactory radiation performances (directivity, radiation efficiency, and gain) with a dual band performance.
