摘要

A high directive electromagnetic bandgap (EBG) antenna operating in a wide frequency band is used to design a monopulse radiation pattern. Four aperture coupled microstrip antennas (ACMA) are used as feeding sources in this EBG antenna, and a frequency selective surface (FSS) is used as a superstrate layer. By suitable design of a wideband feeding network, it is possible to obtain a monopulse radiation pattern in E&H-Planes simultaneously. In this antenna, using the superstrate layer and the ACMA simultaneously, leads to produce a wide frequency band for the antenna reflection coefficient. Also, high directivity is achieved only by using the superstrate layer that has been made by the FSS layer with square loop elements. At first, a wideband ACMA is designed to operate in x-band. Secondly, after the design of optimum superstrate layer by the FSS structure, it is added to the four ACMA in order to increase both bandwidth and directivity. Finally, a wideband feeding network which operates in X-Band is designed to produce monopulse radiation pattern. The EBG antenna operates in three different modes including one sum radiation pattern and two difference radiation patterns in E&H-Planes simultaneously.
