Abstract
A planar antenna apparatus is provided. The apparatus includes a first radiation unit configured to transmit a signal, a first feed unit configured to feed a current to the first radiation unit and apply the signal to be transmitted to the first radiation unit, a first Radio Frequency (RF) ground to which a plurality of antenna elements are grounded; and a via that connects the first radiation unit to the first RF ground, wherein all of the first radiation unit, the first feed unit, the first RF ground, and the via are disposed on a first plane, and wherein a capacitance value between the first radiation unit and the first feed unit and an inductance value determined by a length and a width of the radiation unit are set as values that cause a resonant frequency in a specific frequency band to be a preset value.
