Abstract
A supplemental antenna assembly is provided for use with an electronic device having an integral radio antenna, such as a wireless-enabled laptop computer, notebook computer, gaming device, personal digital assistant (PDA), or circuit card (e.g., a PCMCIA card) or other circuit assembly designed be used with such a device. The supplemental antenna assembly includes a parasitic element supported by a frame. The frame is configured to be attached to the housing of the portable device such that an inductive coupling is provided between the parasitic element and the integral radio antenna. The parasitic element may include, for example, an antenna and/or a coupling element, e.g., a coupling element configured to be connected to an external antenna.
Claims27
A supplemental antenna assembly for use with an electronic device having an integral radio antenna disposed in a housing of the electronic device, the supplemental antenna assembly comprising:
- a parasitic element;
- and
- a frame that supports the parasitic element and that is configured to be attached to the housing of the portable device such that an inductive coupling is provided between the parasitic element and the integral radio antenna.
A supplemental antenna assembly for use with a wireless communications card having an internal radio antenna and configured for removable installation in an electronic device, the antenna assembly comprising:
- a parasitic element;
- and
- a frame that supports the parasitic element and that is configured to be attached to the wireless communications card proximate the internal radio antenna such that an inductive coupling is provided between the internal radio antenna and the parasitic element.
A supplemental antenna assembly for use with a wireless communications PCMCIA card having an internal radio antenna positioned proximate an end thereof, the supplemental antenna assembly comprising:
- a parasitic element;
- and
- a frame that supports the parasitic element and that is configured to be attached to the PCMCIA card proximate the end of thereof such that an inductive coupling is provided between the internal radio antenna and the parasitic element.
