Abstract
The present invention provides a very small volume and broad band antenna for a portable appliance including a transceiver module with an independent ground and an antenna feed conductor, the antenna comprising a first conductive surface lying substantially in a first geometrical surface of non-closed curvilinear shape surrounding an inside space and connectable to the independent ground of the transceiver module of the appliance; and a second conductive surface disposed substantially in a second geometrical surface substantially coinciding with the first geometrical surface and situated in the inside space, and forming a radiating assembly connectable to the antenna feed conductor; whereby the antenna is semi-independent of the elements of the appliance.
