In this paper, a modified circular microstrip patch antenna fed by a microstrip line feed is presented. The main aim
was to improve the narrow bandwidth of microstrip patch antennas while at the same time ensuring that other
important parameters of the antenna such as gain, efficiency, and impedance matching are not affected. The shape
of the patch was modified by adding some parts to it and removing some parts from it with the aim of achieving a
wider bandwidth. High frequency structural simulator (HFSS) was used to simulate and analyze the designed patch.
Simulated results of return loss, VSWR, and Z parameters were then presented. Based on simulated results, the
shape presented showed satisfactory operation in the frequency range 1647-1968 MHz which is within the L-band.
The modified circular microstrip patch antenna showed remarkable improvement in bandwidth as compared to
conventional microstrip patch antenna for return loss of less than -10 dB. The antenna also showed good impedance
matching with the 50 Ω line that was used for simulation. The antenna is suitable for GSM 1800-1900 MHz systems. |
