Abstract

In this paper, we propose a new design in that a new metal strip as an additional resonator is directly connected with a feed strip and positioned at a plane perpendicular to a ground plane and a main dual-resonator patch radiator. With this direct-feed scheme, the forgoing problems relating to the parasitic-feed technique for an additional resonance in a conventional multiple-band antenna can be alleviated. As an example, a quad-band antenna covering the GSM900, DCS1800, PCS1900, and UMTS2000 bands was achieved. The simulations were performed using Remcom software XFDTD5.3, which is based on the FDTD method.
