Design of Array Microstrip Antenna 4x4 Element For Microwave Radio Communication System

This paper proposes the design of array microstrip antenna for microwave radio communication system applications at frequency of 10700 MHz. In order to increase the gain of the proposed antenna, a 4x4 element array method is proposed in this paper.. From the simulation results obtained return loss of -26.57 dB and VSWR of 1.098 at a frequency of 10700 MHz. The bandwidth obtained from the 4x4 element antenna array is 1559 MHz with frequency range of 9682 MHz - 11241 MHz. The gain of proposed antenna is 14.50 dB at a frequency of 10700 MHz. Optimization using the 4x4 element array method has succeeded in increasing the gain up to 35.3 % compared to the 4x2 element array method. The proposed antenna is suitable as a candidate for application in microwave radio communication systems.
