Abstract

A compact design of the single-layer slotted microstrip patch antenna is presented, which has two highly decoupled orthogonal input ports and is capable of generating dual-polarised radiation. The proposed antenna displays a desired characteristic for reducing polarisation loss between the transmitting and receiving antenna units at arbitrary angles. The measured results show that the proposed antenna with resonance frequency at 5.93 GHz has a bandwidth of about 300 MHz, an average gain of greater than 8 dBi, and an input isolation of exceeding 20 dB for the entire impedance bandwidths of the two polarisations.
