Popis:	A circularly polarized cavity antenna that is fed by L-shaped probes is proposed in this paper. This antenna has a simple configuration and good connectivity with a feed circuit. Wideband impedance matching is achieved by using the vertical arm of the L-shaped probe located near the side of the cavity as an impedance transformer, thus eliminating the need for other impedance matching circuits. The effectiveness of the proposed antenna has been confirmed experimentally.
