Abstract
The present invention is related to an omnidirectional planar monopole antenna and mainly comprises a dielectric substrate, a ground plane, a first radiating metal line, a second radiating metal line, and a feeding coaxial line. The dielectric substrate has a first surface, a second surface, and a via-hole to connect the first surface and the second surface. The ground plane has a grounding point. The first radiating metal line is further composed of a first metal strip, a second metal strip, and a third metal strip on the first surface of the dielectric substrate. The first metal strip has a length of about 0.25 wavelength of the antenna's central operating frequency and is with a distance of less than 3 mm to the ground plane. The second metal strip has a length of about 0.5 wavelength of the antenna's central operating frequency and is in the form of a meandered line, whose two ends are connected to the first and third metal strips, respectively. The third metal strip has a length of about 0.5 wavelength of the antenna's central operating frequency. The second radiating metal line, on the second surface of the dielectric substrate, has a length of about 0.25 wavelength of the antenna's central operating frequency. The feeding coaxial line is for signal transmission. The present invention is suitable for application in the 2.4 GHz WLAN band for providing high-gain omnidirectional radiation.
