F-probe fed broadband triangular patch antennas mounted on a finite ground plane

Compact F-probe fed triangular patch antennas are presented in this paper. This novel design enables us to reach good radiation characteristics over the whole impedance bandwidth. Two structures have been proposed. The first one presents several advantages like compactness, wide impedance bandwidth and radiation pattern stability. The second one achieves a wider bandwidth with slight degradation of the radiation pattern. All these advantages make the two antennas very interesting for wireless wideband communication systems.
