Summary:
In this letter, a compact stacked stacked shorted patch antenna is proposed using low temperature cofired ceramic (LTCC) technology. The height of the antenna is decreased due to the shorted pin, and this greatly improves the polarization performance of the antenna. At the same time, the height (about λ /25) of the antenna and its polarization state are determined by both the feeding and the shorting pin of antenna integrated.The antenna is mounted on a 44 × 44 2 mm ground plane to miniaturize the volume of the system. The designed antenna operate at a center frequency of 2.45GHz, and its impedance bandwidth is about 200 MHz, resulting from two neighboring resonant frequencies at 2.41 and 2.51 GHz, respectively. The average gain in the frequency band of interest is about 5.28dBi.
