Abstract
This paper studies the effect of dielectric cover
layer thickness on circular microstrip patch antenna parameters
such as gain, bandwidth, beam-width, radiation patterns, return
loss and VSWR. The proposed antenna is designed with 2.4GHz
frequency in S-Band region. This operating frequency useful in
ISM band applications. Circular patch antenna is designed with
cavity model analysis and simulated using HFSS simulation
software (Electromagnetic simulator). The coaxial probe fed is
used for antenna design. In this paper the effect of dielectric cover
layer on antenna parameters studied experimentally and
comparing their performance characteristics. The simulation
results shows that the antenna without dielectric cover layer
obtained gain is 4.11dB and antenna with dielectric cover the gain
is reduced to 2.87dB to 5.88dB based on thickness of the dielectric
cover layer. The antenna bandwidth obtained without dielectric
cover is 3% and with dielectric cover its bandwidth is reduced from
0.012GHz to 0.052GHz based on thickness of the cover layer
effect. Similarly other parameters are investigated and compared.
This proposed circular patch antenna is used in wireless and
Wi-Fi applications.
