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.
