A broadband probe-fed patch antenna for a DCS base station

This paper presents a novel broadband design of a probe-fed patch antenna, and a constructed prototype suitable for applications in a DCS (1710-1880 MHz) cellular system base station is demonstrated. The proposed antenna has a thick air substrate for broadband operation, and is fed by a probe feed with a short probe pin, which is connected through a triangular conducting patch to one of the patch's radiating edges, By tuning the flare angle of the triangular conducting patch, good impedance matching over a wide frequency range is obtained. Details of the proposed antenna and experimental results of the constructed prototypes are presented and discussed. (C) 2001 John Wiley & Sons, Inc.
