Abstract
An antenna apparatus includes an antenna patch, a feed line, a capacitor, and a ground line. One end of the feed line is connected to the antenna patch. The other end of the feed line is connected to the capacitor in series. One end of the ground line is connected to the antenna patch. The other end of the ground line is configured to connect to the ground plane. The antenna patch and the ground plane remain spaced apart. The antenna patch, the feed line, the capacitor and the ground line are together arranged in a configuration to excite operation modes corresponding to three resonances.
