Design and Simulation of Microstrip Phase Array Antenna using Circular Patches

Microstrip antennas are used in variety of wireless applications including radars, cellular phones, wireless sensor networks, and in medical applications. The objective of this research is to design a circular patch microstrip phase array antenna which can resonate at UHF i.e. 10 GHz and later on improve the design and include phase steering in this design. Two circular patches with radius of 5.83 mm each are used in this design. The proposed antenna is excited through coaxial probe feed using Wilkenson power divider rule. ADS Momentum software is used to simulate the proposed antenna. Various parameters for example S11 Parameter, return losses, directivity, efficiency and gain of the proposed antenna is also obtained using ADS Momentum.
