Abstract

Microstrip antennas offer good electrical performance, aesthetic designs, and potentially low cost - features which make them very attractive for application in cellular phone systems, wireless local loop networks, PCS systems, and wireless data transmission systems. The aperture coupled microstrip antenna, invented at the University of Massachusetts at Amherst in 1985, provides bandwidths up to 35%, and has become one of the most useful planar antenna designs for commercial wireless systems. This paper will summarize the features of aperture coupled microstrip antennas, and present several examples for such antennas and arrays. These will include a low gain element designed for the full AMPS T/R band (824 - 895 MHz), a medium gain array for the PCS band (1850 - 1990 MHz), and a low gain element covering the L1 and L2 bands (1575 MHz and 1227 MHz) for GPS applications.
