A Study of Design Strategy of Micro Strip Antenna Array Towards Wireless Communication

electronics & communication

In the recent years the development in Wireless systems requires the development of low cost, minimal weight and low profile antennas that are capable of maintaining high performance over a wide spectrum of frequencies. This technological trend has focused much effort into the design of a microstrip patch antenna. The objective of this paper is to design, and fabricate a fed rectangular microstrip patch antenna (E-Shape). The operating frequencies of antenna are from 1.85GHz to 1.99GHz, which governs the resonant frequency 1.9GHz of the antenna. Two parallel slots are cut to perturb the surface current path that is corporate into the patch to expand its bandwidth. Initially we set our antenna as a single patch and after evaluating the outcomes of antenna features; operation frequency, radiation patterns, reflected loss, efficiency and antenna gain, we transformed it to a 1x2 linear array. Finally, we analyzed the 1x4 corporate feed linear microstrip patch array antenna that has been designed with dielectric constants of 𝛆𝐫=2.2 with fixed substrate height of h=1.5748mm (substrate RT/ Duroid 5880).
