This paper presents the design and development of a four‐element, corporate feed, linear subarray for possible use in a base‐station antenna developed for the DCS1800 system. The subarray, with the main beam 30° off boresite toward the ground, uses strip‐slot‐foam inverted‐patch construction to increase the operational bandwidth. The design was carried out using a combination of the commercial software packages Ensemble and PCAAD. Experimental and simulated results for return loss and radiation patterns are presented and compared; a good agreement is seen in the return loss results, and the main beam is tilted as predicted; however, the measured sidelobe levels are higher than desired. ©1999 John Wiley & Sons, Inc.
