Rectangular Microstrip Patch Antenna at ISM Band

The research work of design, simulation, development, and measurement done on the rectangular microstrip patch antenna for the ISM band of frequencies is presented in this paper. This rectangular patch antenna is fed by a microstrip line feed. Its resonance frequency performance is studied between 2.4-2.5 GHz. This band of frequencies is ISM band of wireless applications. The design and simulation are done in Advanced Design System (ADS) software with FR4 substrate. According to its real application, the material, shape, and the type, the microstrip antenna is designed. The size of the antenna is calculated by the length, width expressions. Then the antenna is simulated for the radiation parameters obtained through optimizing and matching to meet the requirements. The parameters of antenna such as Reflection coefficient, Gain, VSWR and Band width are measured using Network Analyzer and found satisfactory with simulated results. Compared to earlier antenna design, the proposed antenna exhibits more gain.
