Abstract

In this article, a couple of monopole line-fed UWB antennas with different configurations are presented. Antenna shapes include a big circle overlapped with four small circles, and a two overlapped circles in the horizontal direction. Configurations include single element antenna, single element antenna with dual band reject filters, and polarization diversity antenna version. Measurements show that all antennas work well within almost the whole UWB. The polarization diversity version has a practical port isolation (S₁₂ and S₂₁) better than -15 dB, an Envelope Correlation Coefficient lower than 0.019 and a diversity gain higher than 9.96 dB.
