Abstract

An antenna is used to receive RFmicrowave signals, while a rectifier converts these signals into DC power. In this work, the design and simulation of a rectangular microstrip patch antenna and its array are carried out at a frequency of 2.45 GHz for low-profile wireless applications. Initially, a single rectangular microstrip patch antenna is designed at 2.45 GHz using an electromagnetic solver, and its design parameters are optimized accordingly. A 12 rectangular microstrip array is then developed using a feed network, maintaining the same frequency. The inter-element spacing is set at 0.75. Key antenna radiation characteristicsincluding return loss, gain, directivity, efficiency, and 3D radiation patternsare obtained for both the single patch and the array configuration. A comparative analysis reveals that, with an increased number of elements in the array, the gain improves while the beamwidth narrows, as observed in the simulation results.
