  • Inverted-F antenna
    Patent number: 6894647
    Abstract: A coupled-feed inverted-F antenna is provided comprising a transmission line port, an open radiator with an unterminated end, a shorted “L” shaped radiator connected to the open radiator with a terminated end, a coupled-feed connected between the transmission line port signal interface and the open and shorted radiators, and a groundplane. The coupled-feed is oriented parallel to the open radiator. A coplanar inverted-F antenna is provided comprising a transmission line port, an open radiator oriented in a first plane, a shorted “L” shaped radiator oriented in the first plane connected to the open radiator and having an terminated end, a feed oriented in the first plane and connected between the transmission line port signal interface and the radiators, and a groundplane oriented in the first plane. The shorted radiator is terminated in the transmission line port ground interface. The antenna may also employ both coplanar and coupled-feed features.
