Abstract
A robust, dual-band, omnidirectional antenna is provided. In some embodiments, the antenna can be deployed in a Wi-Fi access point and tuned to operate with high efficiency in a plurality of driving point environments, and in some embodiments, the antenna can be tuned to operate with high efficiency over an impedance bandwidth in excess of 80% with little change to the radiation patterns. The antenna can operate in a TMcircular patch mode in a low frequency band and in a wideband quarter wavelength monopole mode in a high frequency band, and both the TMcircular patch mode and the quarter wavelength monopole mode can radiate a strongly circulating magnetic field that can beget excellent omnidirectional radiation patterns and decouple the antenna from nearby horizontally-polarized antenna elements, thereby allowing the antenna to be collocated with horizontally-polarized elements with little degradation to overall system level performance.
