A cavity-backed slot/strip loop antenna is proposed for a broadband CP operation. The slot/strip loop is a combination of a slot loop and a strip loop. The slot loop radiates a CP wave at a lower frequency while the strip loop produces CP radiation at a higher frequency. A combination of the two frequencies leads to a bandwidth enhancement. The

A low-frequency annular-slot antenna - NIST Page A Low-Frequency Annular-Slot Antenna James R. W ait The radiation characteristics of an annular slot cut in an ideally conducting ground plane are discussed. The voltage impressed between the concentric edges is assumed to be constant around the slot. The annular slot is backed by a hemispherical cavity which has A STUDY OF A COMPACT MICROSTRIP-FED UWB ANTENNA WITH AN ... A STUDY OF A COMPACT MICROSTRIP-FED UWB ANTENNA WITH AN OPEN T-SLOT X.-F.
