Design and performance analysis of the rectangular spiral microstrip antenna and its array configuration

In this paper a rectangular spiral microstrip antenna and its array configuration are designed and their performances are analyzed in term of return loss response and radiation pattern. Microstrip antenna design equations are introduced and the proposed antenna is simulated by using SONNET version V12.56 simulator. The resonant frequency of array antenna is 10.6 GHz. The main feature of this spiral antenna is that it can be designed for the operating frequency at any range with higher radiation efficiency compared to other conventional microstrip antennas and its array network configuration provides higher radiation performance in term of directive gain and maximum radiation.
