Annotation

The antenna described in this letter uses a stepped T-shaped structure in combination with patch tapering and a capacitive feeding mechanism to obtain broad bandwidth (BW).

Abstract

This antenna is designed to operate for U.S. Public Safety (PS) and Long Term Evolution (LTE) wireless communication bands covering 426-861 MHz (68 percent 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 ~ 0.25 ë in length and height being ~ 0.01 ë 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 described in this letter.
