Abstract

A novel printed crossed dipole with broad circular polarisation (CP) is proposed. This dipole is also utilised in 1 × 2 and 2 × 2 array antennas. The proposed dipole can produce CP because of its sequentially rotated configuration. The broadband CP performance is achieved because of a parasitic dipole crossing over the original dipole with a 90° phase delay line. The experimental results show that single, 1 × 2, and 2 × 2 antennas yield bandwidths of 15.6, 24.5, and 39.2 for 3dB axial ratio, respectively.
