- Abstract
This paper presents a novel wideband to narrow band reconfigurable log periodic aperture coupled patch array. The wide to narrow band reconfiguration is realized by closing a selected group of slot apertures, to deactivate the corresponding group of patches. 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. Potentially, the number of sub bands can be increased or decreased as can the bandwidth of the sub bands by selecting a specific number of active elements. To verify and demonstrate the proposed design method, a prototype has been developed with ideal switches. Very good agreements between the measured and simulated results are presented.
