Abstract : Design and realization of circular micro strip antenna array in S band isreported in this research paper. It is shown
that the design adopted foe circular micro strip antenna array is quite accurate. By using the conventional microwave
integrated circuit technology compact, lightweight micostrip antenna array can be realized. The desired narrow band is
achieved for the circular micro strip antenna array. Circular micostrip antenna array are designed and fabricated on the
substrate of glass epoxy which is easily available and low cost.Substrate has a dielectric constant of 4.22and thickness
1.6mm.Simulation is done using HFSS to achieve the desired results. Also design and fabrication of circular micro strip
antenna array done on glass epoxy substrateusing photolithographic process. Then measurement is taken on vector
network analyzer in anechoic chamber. A simulated and measured result exactly matches with each other with slight shift in
frequency due to low quality substrate. The proposed circular micro strip antenna array has the simulated return loss of -
11.66 dBat a frequency of 2.4 GHz. The actual fabricated circular micro strip antenna array hasmeasured return loss of -
14.553dB at a frequency of 2.378GHZ.Simulated VSWR has a value of 1.705at a frequency of 2.4Ghz. Actual VSWRhas a
value of 1.6985 at a frequency of 2.370Ghz.From smith chart it is seen that at a frequency of 2.370 Ghzrealresistance offered
by circular micro strip antenna array is (62.852Ω, 131.50Ω) and inductance offered by circular micro strip antenna array is
8.3717nH. From these values it is seen that simulated and actually measured values exactly match with each other. From
VSWR value it is seen power loss within the circular micro strip antenna array is very little and most of power get radiated.
From impendence value it is seen that when impendences matches perfectly maximum power get transferred from
transmitter to micro strip line and antenna.
