A Novel Low Profile Dual-Frequency Shorted Patch Antenna

Abstract

Dual-frequency planar antennas can substitute large bandwidth patch antennas, where there is a requirement for large bandwidth to cover two separate transmit receive bands. In this paper a novel single-feed, single layer, double-band, compact short loaded patch antenna is studied theoretically and experimentally. Besides the compactness, this design provides, dual frequency operation with a small frequency ratio of 1.3 between the two resonant bands. Various radiation characteristics are simulated as well as experimentally studied and good concurrence is observed between the simulated and measured results.
