Abstract: Microstrip rectangular patch array antenna was designed and comparative
study is done on two promising materials namely liquid crystal and RT-duroid
substrates. The antenna parameters are simulated using commercial Ansoft
HFSS software and the detailed explan ation of performance evaluation is
presented. A 4x4 rectangular patch array was designed on two substrate
materials and their return loss, input impedance, gain, radiation patterns and
antenna parameters are studied at 10GHz and presented in this paper. The
applicability of the rectangular patch array antennas on these two substrate
materials are discussed regarding the applications, cost, weight and
performance.
