2.45 GHz of elliptical shape patch antenna

This paper describes the design of multiple element of co-polarization elliptical patch antenna operating at 2.45GHz. Computer Simulation Technology (CST) Microwave Studio is used as an effective tool for 3D electromagnetic simulation of high frequency design. In this paper, different dimensions with three elliptical shaped slots are implemented and attached with main radiating element while power has been excited from coaxial feeding. Radius of 14 different cylindrical dots are located at the left most center of the smallest elliptical slot. The analysis on performance will be based on the obtained result especially in radiation pattern, bandwidth and return loss. The antenna is capable of functioning with a maximum directivity of 6.948dBi and a return loss of -22.87dB.
