Abstract

An antenna for improving an influence of surface waves and increasing a beamwidth includes: a substrate, a first metal ground, a second metal ground, an emitting end and a receiving module. The first metal ground and the second metal ground are disposed on a first surface of the substrate. The second metal ground is completely separated from the first metal ground by a first gap. The emitting end is disposed on the first metal ground and includes a transmission line and a plurality of radiating elements. The receiving module is disposed on the second metal ground and includes a first receiving end and a second receiving end. The first receiving end includes a transmission line and a plurality of radiating elements. The second receiving end includes a transmission line and a plurality of radiating elements.
