ABSTRACT:
A wireless communication device (100) comprises an antenna (204) comprising a major radiating element (210) that includes a letter C shaped part (212) connected to a letter U shaped part (214). The major radiating element (210) is spaced from a ground plane (302) and one or more components (206, 208) having conductive parts are located between the major radiating element (210) and the ground plane (302). Openings (314, 316) in the ground plane (302) are located under the components (206, 208) or terminals (310) of the components (206, 208). Passive radiators (126, 700) having multiple sections (602, 604, 702, 704, 706) of different transverse dimension are located on a flip (110) of the wireless communication device (100) proximate the antenna (204).
