Abstract

In this paper, we study a rectangular microstripline‐fed wide aperture‐coupled microstrip antenna backed by a ground plane. In this case, a rectangular microstrip feed line and a wide slot lead to good impedance matching in a wide‐frequency band. The 2.0 VSWR impedance bandwidth of the lower mode is 0.29 GHz (0.83–1.12 GHz, 32.2% at the center frequency of 0.9 GHz) and covers the cellular and GSM bands; the band of the upper mode reaches 0.93 GHz (1.69–2.62 GHz, 46.5% at the center frequency of 2.0 GHz) and covers the PCS, IMT‐2000, WLL, and UMTS bands, in respectively. The results obtained for VSWR exhibit multiband characteristic. The peak antenna gain is 7.6 and 10.5 dBi for the lower (Cellular, GSM) and upper (DCS, PCS, IMT‐2000, WLL) operations, respectively. © 2004 Wiley Periodicals, Inc.

In this paper, the tilt of a feedline with regard to a slot is taken into account to impro¨e the ca¨ity model, and also to see the effect of this angle on the input impedance. In fact, the angle is introduced in the ¨oltage discontinuity of the slot on the feeding line. The computed results are comp
