Abstract

A low-profile, planar, super-wideband (SWB) antenna pair has been developed to achieve polarization diversity. Its unique configuration brings superior compactness and bandwidth. A novel technique is developed to force one printed patch to play two roles and hence to achieve polarization diversity using only three printed patches, as opposed to four in a conventional diversity pair, to maximize the usage of the limited area available in a compact wireless device. The measurements confirm extremely wide impedance bandwidths of 0.86-30 and 1.04-27.2 GHz at the two ports. That means the ratio bandwidth for each polarization is greater than 26:1. Moreover, the antenna displays sufficient isolation between the two ports and good envelope correlation coefficient for diversity over its operating frequency range. The measured radiation patterns corresponding to each port are also presented.
