Abstract

An antenna (100) includes a radiating unit, a feeding element (6), and a conductive coupler (5). The radiating unit includes a pair of parallel first and second radiating elements (3, 4). The feeding element (6), which supplies an antenna current from an external source to the first and second radiating elements (3, 4) of the radiating unit, is coupled to the first and second radiating elements (3, 4) of the radiating unit. The conductive coupler (5) is coupled to the first and second radiating elements (3, 4) of the radiating unit for enabling the antenna current to flow along the first and second radiating elements (3, 4) of the radiating unit in opposite directions.
