Abstract

A compact wideband dual-polarized microstrip antenna element for phased-array antennas is presented. The feeding lines are distributed on two layers, which facilitate the design of complex antenna arrays. The antenna element has a return loss greater than 10 dB, and an isolation between the input ports over 35 dB from 10.7 to 12.6 GHz. Also, a four-element array is constructed and measured. © 2001 John Wiley & Sons, Inc. Microwave Opt Technol Lett 28: 396–398, 2001. [ABSTRACT FROM AUTHOR]
