Abstract
A microstrip antenna (100) achieves wider bandwidth by using an asymmetric radiating structure (110). The radiating structure (110) supports at least two resonating modes, which are preferably a differential and a common resonating mode. A feed system (130, 135) is coupled to the radiating structure (110) to excite the respective resonating modes at different frequencies to provide a radiating band for communication signals. Preferably, the antenna (100) includes patch radiators (112, 114) of substantially different widths, and a buried microstrip line (130) that simultaneously feeds the patch radiators (112, 114).
