Abstract
In this paper, a wideband dual-polarized open-ended waveguide based on the open-ended circular waveguide antenna by adding special inverted ridge structure is proposed. It can be applied to Near-Field measurements. The antenna operates a wide bandwidth ranged from 6 to 15.3 GHz with| S 11 | < −10dB. Compared to the standard open-ended circular waveguide, it has less scattering due to the aperture size of 0.43λmax. The isolation is greater than 45dB and the cross-polarization discrimination is greater than 40 dB across 6-15.3GHz. The antenna gain is from 5.4 to 11.4 dB and beamwidth is from 40° to 100° over the entire band.
