Abstract
In this paper, a compact differential-fed antenna with filtering responses is proposed. The antenna is composed of two radiating patches and a differential-fed circuit embedded with two u-shape slots which generate two notches. The stacked patch is employed to further improve the impedance bandwidth to fit the LTE communication application. The proposed antenna achieves the 18% impedance bandwidth. The average gain within the bandwidth is 9.5 dBi with less than 0.5 dB variation. The cross polarization ratio is less than 30dB. Out of the operating band, the gain drops sharply, exhibiting a bandpass response.
