Slot antenna device
First Claim
1. An antenna device for at least one of transmitting and receiving radio frequency (RF) waves and that is connectable to a radio communication device including signal processing circuitry, the antenna device comprising:
- a substantially planar conductive antenna element provided with a feeding point, a grounding point and a slot located between the feeding point and the grounding point;
a substantially planar ground conductor in a plane substantially parallel with said planar conductive antenna element;
a grounding connector that connects said planar ground conductor to the grounding point; and
a feeding connector that connects the signal processing circuitry to the feeding point, the antenna device being connectable to the radio communication device such that said planar ground conductor is located between said planar conductive antenna element and the signal processing circuitry to shield the signal processing circuitry from RF waves.

Abstract
A slot antenna device for transmitting and/or receiving radio frequency (RF) waves, connectable to a radio communication device including signal processing circuitry, includes a substantially planar conductive antenna element provided with a slot, and with feeding and grounding points respectively located at opposite sides of the slot; a substantially planar RF ground conductor located substantially in parallel with the planar conductive antenna element; a grounding connector connecting the planar ground conductor to the grounding point; and a feeding connector connecting the signal processing circuitry to the feeding point. The antenna device is connectable to the radio communication device such that the planar ground conductor is located between the conductive antenna element and the signal processing circuitry, to effectively shield the circuitry from RF waves.
