Abstract :
The design of a novel single-fed circularly polarised antenna dedicated for dual-band operations is presented. It is realised by integrating a dual-band dual-fed patch antenna with a dual-band branch-line coupler in a compact multi-layer structure. Measured impedance bandwidths of 20.1% (895 MHz) and 8.9% (2.397 GHz) are achieved.
