Design and Simulation of the Series-Fed Microstrip Antenna Arrays

Abstract

This paper designed two kinds of series-fed microstrip patch antenna arrays. For each antenna array, the rectangle patch antenna elements were employed. In order to achieve high gain and the normal radiation pattern, each antenna element should have the same excited amplitude and phase. The radiation performances were realized by use of the proper feeding structure. The discussed antenna arrays were simulated and optimized through full wave electromagnetic simulation software. For the same operational frequency, the two designed microstrip antenna arrays have anticipated working performances. The simulated gains of these two antenna arrays are higher than 11dBi and the simulated voltage standing wave ratio (VS WR) of each antenna array is less than 2 at the working frequency. The simulation results in this paper are provided, which can be used as a technical reference for the practical engineering application.
