Rf mems integrated frequency reconfigurable annular slot antenna

By activating/deactivating the RF MEMS actuators, which are strategically located within the antenna geometry and microstrip feed line, the operating frequency band is changed. The RA annular slot has two reconfigurable frequencies of operation with center frequenciesf low = 2.4 GHz andf high = 5.2 GHz, compatible with IEEE 802.11 WLAN ... 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
