Suspended plate antennas with shorting strips and slots

The suspended plate antennas (SPAs) with shorting strips and slots are presented numerically and validated experimentally. Effects of narrow shorting strips on the impedance and radiation performances of the SPAs are studied. The symmetric use of shorting and feeding strips makes the SPAs structurally symmetrical, which is conducive to the radiation performance of the SPAs. Also, effects of narrow rectangular slots cut in the center or the edges of the plates are investigated. Cutting the slots reduces size, realizes dual-band operation, and improves radiation performance of SPAs.
