Abstract :
A novel single-feed compact dual-frequency design is demonstrated. The proposed design consists of a rectangular patch loaded with two parallel slots close to the radiating edges and meandered with slits at the non-radiating edges. The two operating frequencies have parallel polarisation planes and, by varying the insetting slit length, the frequency ratio of the two frequencies is tunable in the range of ~1.8-2.4. In addition, with the insetting slit, the two frequencies can be greatly lowered, which results in a large antenna size reduction for fixed dual-frequency operation
