Abstract

In this paper, an ultra‐broadband patch antenna using a wedge‐shaped air dielectric substrate is introduced. By adjusting the angle α, the experimental ratio bandwidth of S~11~ ⩽ −10 dB reaches 8.8:1, covering frequencies from 3.05 to 26.87 GHz. The measured impedance locus and radiation patterns at f = 6 GHz and at f = 18 GHz both are presented, and they show broadband characteristics and stability across the whole operating frequency bands, respectively. © 2005 Wiley Periodicals, Inc.
