Improvement of Isolation between Transmitting and Receiving Antennas of E-plane arranged Waveguide Slot Arrays by using Layers of Slit pairs with Half-wavelength Spacing
In this paper, we propose loading layers of slit pairs with halfwavelength spacing over a corporate-feed waveguide slot array antenna in the 30GHz band. This structure is expected to improve the isolation between transmitting and receiving antennas arranged in the E-plane. As a result of the design, the reflection of the radiating element is suppressed under -14dB over a target band (27.8 GHz - 31.4 GHz). The isolation between two antennas using a 2x32-element model is improved by about 20 dB comparing to the conventional structure without the slit-pair layers.
