摘要
A novel reconfigurable low profile log periodic patch array is presented. The patches are fed with a modulated meander line through aperture slots. A wideband mode from 7-10 GHz and three selected narrow band modes at 7.1, 8.2, and 9.4 GHz are demonstrated. The wideband to narrow band reconfiguration is realised by bridging the slot aperture, effectively deactivating the corresponding radiating element. Potentially the proposed method offers a very fine control of a narrow passband. Measured and simulated results with very good agreement are presented, thus verifying the proposed concept.
