Microstrip Patch

This paper presents the design of a compact circular microstrip patch antenna for WLAN applications which covers the band 5.15 to 5.825 GHz. The antenna is designed using 1.4mm thick FR-4 (lossy)substrate with relative permittivity 4.4 and a microstrip line feed is used. The radius of the circular patch is chosen as 7.62mm. To reduce the size and enhance the performance of the proposed antenna, a circular slot is loaded on circular patch and a square slot is etched on the ground plane of dimension 30mm×30mm. Design of the antenna is carried out using CST Microsoft Studio Sonimulation Software. The proposed antenna resonates at 5.5 GHz with a wider bandwidth of 702 MHz and it provides low return loss of -31.58 dB, good gain of 3.23 dB and directivity of 4.28 dBi and high efficiency of around 79% against the resonance frequency. The geometry of the proposed circular antenna with reduced size and its various performance parameters such as return loss, bandwidth, VSWR, gain, directivity, efficiency and radiation pattern plots are presented and discussed

Feeding Technique

Double Fibonacci spiral in a circle with microstrip line feeding technique is designed in the frequency range from 0.1GHz to 6GHz. The antenna is designed and simulated in computer simulation technology microwave studio software, substrate Fr-4 with thickness 1.59mm is used and antenna parameters such as return loss, surface current, E-field, H-field and gain are calculated for Double Fibonacci spiral microstrip patch (DFSM) antenna. The antenna is used for ISM (industrial, scientific and medical) frequency band (2.45GHz) and a new unutilized band for next generation services, gain is 2.22dB and 3.16dB and bandwidth is 25.94% and 22.83% on resonating frequencies.
