- Abstract
A dual-port pattern diversity antenna is proposed in this letter for omnidirectional coverage. Two end-fire radiating beams are realized based on a two-element magnetic current array. A folded half-mode substrate integrated waveguide (FHMSIW) is introduced to ensure that the distance between the two equivalent magnetic current radiation sources is about λ0/4 (λ0 is the wavelength in free space). When the two elements are driven by signals with a 90◦ or -90 ◦ phase difference, two end-fire radiation patterns with opposite directions can be realized. A prototype working at 2.425 GHz is fabricated and tested, achieving two independent end-fire radiation beams with a maximum gain of 4.3 dBi. Compared with conventional omnidirectional antennas, this work can effectively improve the gain of omnidirectional coverage based on a very compact structure.
