SLOT COUPLED PATCH ANTENNA

摘要

PROBLEM TO BE SOLVED: To provide an antenna including a radiation element which provides the best performance characteristic at receiving a circularly polarized wave RF signal. SOLUTION: The antenna to receive and/or send the circularly and/or a linearly polarized wave RF signal includes the radiation element, a ground plane, a dielectric substrate, and a feeder. The radiation element is arranged on a glass pane. The radiation element demarcates a slot having a first leg and a second leg to form a cross shape to generate the circularly and/or linearly polarized wave. The cross-shaped slot includes a central point. The ground plane is arranged in parallel with the radiation element and in a space apart from the radiation element. The dielectric substrate is put between the radiation element and the ground plane. The feeder extends in a dielectric layer and is electromagnetically coupled to the radiation element and the ground plane. The feeder terminates at a remote position end in front of the central point of the slot. The feeder does not cross the central point. The antenna has a compact size and is at a positive angle to the glass pane. COPYRIGHT: (C)2006,JPO&NCIPI
