Dual-polarized broad-band microstrip antennas fed by proximity coupling

摘要

A novel antenna structure for dual polarisation is proposed. Advantages over previous structures include simplicity, broad bandwidth, high isolation between ports and low cross-polarization. The antenna design is readily suited to use as an array element and therefore has potential for use in a variety of practical applications. The work was supported in part by EPSRC grant GR/S42538/01.
