摘要: An omnidirectional antenna (100) includes a resonator (102) and a ground plane (104). The resonator (102) includes a dielectric substrate (402) having a top conductive plate (404) and a bottom conductive plate (406), wherein the top conductive plate (404) is shorted to the bottom conductive plate (406) proximal to a first end (436) and open at a second end (438) of the dielectric substrate (402), a resonator feed (416) having a location between the first (436) and second (438) ends, a first resonator ground (424) and a second resonator ground (408) coupled between the bottom conductive plate (406) and the ground plane (104), the first resonator ground (424) being contiguous to the bottom conductive plate (406) and having a location which is distal to the first end (436) for suppressing undesirable resonator resonance, and the second resonator ground (408) being contiguous to the bottom conductive plate (406) and having a location which is proximal to the first end (436) for controlling a radiation pattern of the resonator (102) to produce a substantially omnidirectional antenna beam pattern.
