Antenna for radio communications apparatus |
摘要 |
An antenna for a radio communications apparatus operates in the frequency range of 800 MHz-3 GHz. The antenna has two radiating elements. The first radiating element is a slot in a substantially planar foil or disc-shaped metallic conductor. The second radiating element has a resonance frequency which is different from that of the first radiating element. The metallic conductor is placed close to a second conductor in the form of a metallic surface. The second radiating element is formed from an edge portion of the first conductor or a gap between the first and the second conductors. Capacitance devices may be disposed between the edge portion and the second conductor.
