Broadband dual-polarized patch antennas with hybrid feeds for 1800-MHz band operation

摘要

We propose new designs of broadband dual-polarized patch antennas fed by using the capacitively coupled feed and slot-coupled feed. The hybrid feeding structures in the proposed designs include the use of two capacitively coupled feeds of a 180/spl deg/-phase shift and a slot-coupled feed for the excitation of a broadband patch antenna.
