Abstract
A dual-frequency patch antenna with monopolar radiation patterns at both working frequencies is presented in this paper. The antenna design is based on a conventional patch with two concentric short-circuited conditions with a separating gap between them. Both shorting conditions are implemented with vias between the patch and the ground plane. These conditions impose two modes with a uniform electric field distribution both in phase and amplitude at the edge of the patch antenna. These modes result in a monopolar radiation pattern at two different frequencies. The working frequencies can be arbitrary set and depend on the patch dimensions and the location of the shorting vias. Two feeding strategies have been studied: a single coaxial probe which excites both monopolar modes and a different coaxial probe for each mode. A two-port design working at 2.6 GHz and 4.8 GHz is presented, obtaining the desired monopolar radiation pattern at both frequencies. High isolation between the feeding ports is achieved.
