Abstract

A tripolarization and low-profile planar antenna is designed, prototyped, and tested for WLAN application. The developed three-port antenna provides three orthogonal polarization radiations. Two slot-coupled microstrip antennas and a disk-loaded monopole are integrated into one structure. The total height of the antenna is 5.8 mm. Obtained gain for the two slot-coupled directive elements at 2.42 GHz is 7 dBi, while the gain for the monopole omnidirectional element is 2.5 dBi. The bandwidths of the three elements are 2.352.52, 2.32.54, and 2.382.49 GHz, respectively. Simulation results of the radiation patterns are presented and validated by experimental measurements.
