Reconfigurable Patch Antenna Radiations Using Plasma Faraday Shield Effect

Abstract : This letter presents a new reconfigurable antenna associated with a plasma Faraday shield effect. The Faraday shield effect is realized by using a fluorescent lamp. A patch antenna operating at 2.45 GHz is placed inside the lamp. The performance of the reconfigurable system is observed in terms of S11, gain and radiation patterns by simulation and measurement. It is shown that by switching ON the fluorescent lamp, the gain of the antenna decreases and the antenna system (patch+lamp) keeps a good matching at the operating frequency. This reconfigurable antenna can be used to avoid coupling with other communications or radar systems working in the same frequency band.
