Article: A multilayer microstrip patch antenna subarray design using CAD.

This article describes the design and development of an X-band, linearly polarized 4 x 4 element aperture-coupled microstrip patch antenna (ACMPA) subarray with a corporate feeding network. To reduce the design cycle time, commercially available CAD software packages are utilized in the antenna design process. The Ensemble[R] software package is used to obtain dimensions of a single multilayer microstrip patch antenna element. The feed network for the subarray is optimized using Touchstone[R] software. The overall design is verified experimentally by performing return loss, radiation pattern and gain measurements. This experimental part is useful in determining the accuracy ...
