| 摘要 |
A slot antenna device for transmitting and/or receiving radio frequency (RF) waves, connectable to a radio communication device including signal processing circuitry, comprises a substantially planar conductive antenna element (23) provided with a slot (25), and with feeding and grounding points, respectively, located at opposite sides of said slot (25); a substantially planar RF ground plane conductor generally located substantially in parallel with said planar conductive antenna element; a grounding connector connecting said ground plane conductor to said grounding point; and a feeding connector connecting said signal processing circuitry to said feeding point, wherein said antenna device is connectable to said radio communication device such that said ground plane conductor will be located between said conductive antenna element (23) and said signal processing circuitry to effectively shield said circuitry from said transmitted and/or received RF waves.
