Dual frequency microstrip patch antenna with improved feed and increased bandwidth |
摘要 |
A dual frequency stacked microstrip patch antenna is comprised of a pair of circular radiating patches separated by a layer of dielectric, the two upper patches being further separated by another layer of dielectric from a pair of separated ground planes. A modal shorting pin extends between the patches and ground planes, and the patches are fed through a pair of feed pins by a backward wave feed network. A pair of pear-shaped holes in the lower patch through which the feed pins pass balance the impedance between the patches and result in an extended bandwidth.
