| contents | Substrate integrated waveguide cavity‐backed slot antenna with low cross‐polarization over the full bandwidth Arvind Kumar Microwave and Optical Technology Letters AbstractHere, a single‐layered single‐fed slot antenna is realized with low cross‐polarization over the full operating bandwidth. This design consists of a circular‐shaped cavity resonator, employed by using substrate integrated waveguide (SIW) technique and a square‐ring slot on the upper metal cladding of the cavity. The antenna is fed using a probe feed which excites the design in dual mode, that is, slot mode and inset patch mode. Due to the proximity of these dual resonances, the antenna operates over a relatively wider bandwidth than previously suggested designs with the claim of low cross‐polarization. The proposed design helps to realize more than 35 dB of co‐to cross‐pol isolation in both E and H planes. Overall experimental results demonstrate a good radiation performance, it is confirming up to 15–20 dB improvement in cross‐polarization level with enhanced enhancement bandwidth which makes it appropriate for a modern wireless application. 10.1002/mop.34019 http://onlinelibrary.wiley.com/termsAndConditions#vor |
