Design of a Microstrip Antenna Array Dual Band Using Stub Method

Abstract

Microstrip antennas have several advantages, including compact form, small dimensions, easy to be fabricated, easily connected and integrated with other electronic devices. One of the microstrip antenna applications is for data communication. In this research, a dual-band microstrip antenna is designed that works at a frequency of 1.8 GHz and 2.25 GHz. After iteration and simulation, the antenna parameters obtained are return loss at 1.8 GHz frequency of -25.1 dB, and at 2.25 GHz frequency of -36.85 dB. While the VSWR value at a frequency of 1.8 GHz was 1.116, and at a frequency of 2.25 GHz it was 1.029 dB.
