Abstract
In this study, we introduce a dual-band ground radiation antenna using an endless metal-rim mode control method that operates in the WLAN band. In the proposed antenna, the metal-rim modes are excited as one- and two-wavelength-mode radiators by a dual-band ground radiation antenna, which occupies a small space on the ground plane. The metal rim surrounds the ground plane with a gap of only 2 mm. In addition, two capacitors are inserted between the ground plane and the endless metal rim to control the one- and two-wavelength modes of the endless metal rim. Based on simulation and measurement results, we noted that the proposed antenna has an impressively high radiation performance.
