摘要：
The antenna presented in this letter employs a stepped T-shape structure in combination with patch tapering and a capacitive feeding mechanism to obtain broad bandwidth (BW). This antenna is specifically designed to operate for US Public Safety (PS) and Long Term Evolution (LTE) wireless communication bands covering 426-861 MHz (68% BW). The radiation pattern over this broad bandwidth remains almost unchanged with good gain flatness. The antenna has a compact three-dimensional structure with lateral dimensions being similar to 0.25 lambda in length and height being similar to 0.01 lambda at the lowest frequency of operation. The measured and simulated impedance and radiation characteristics results agree well, demonstrating the good performance of the broadband and compact antenna presented in this letter.
