A Small Size, High Gain Antenna for Wireless Base Station Applications

摘要

A single-element high gain compact microstrip antenna has been experimentally demonstrated to operate over a wireless band, covering 8 percent impedance bandwidth. As much as 11 dBi peak gain with linearly polarized radiation has been achieved using a prototype designed for personal communication systems (PCS: 1850 to 1990 MHz). The prototype occupies only 0.15λ_0 × 1.0λ_0~2 space, λ_0 being the wavelength corresponding to the center frequency. This antenna is aimed to communicating with the wireless base stations as a booster/repeater device to serve a microcell in a weak signal zone.
