Abstract
An approach to improve cross-polarisation (XP) radiation in probe-fed microstrip antennas is presented in this letter. The notable XP associated with self-diplexing antennas caused by radiator multiplexing is discussed for the first time. In order to enhance the interport isolation and polarisation purity, the proposed antenna exploits the combined advantages of the defected ground structure (DGS) and shorting pin arrays. Experimental results show that the resonant frequencies of the self-diplexing antenna are 9.56 and 11.28 GHz, accompanied by a port-to-port isolation of more than 29.4 dB. The suppression of XP around 50° range on either side of the boresight in both principal planes is greater than 12.3 and 11.1 dB for ports 1 and 2, respectively.
