As an example, the dual-reflector antennas of spheroidal wave function distribution and uniform distribution have been used. For spheroidal wave function distribution, we have obtained transmission efficiency of nearly 95%, whereas for the uniform distribution, only 80% has been obtained. ## CONCLU

Abstract
Input impedance‐tuning methods are proposed for antenna designs of mobile communications devices. The proposed method can be applied to input impedance‐tuning of single‐band, dual‐band, and multiband planar inverted‐F antenna. The prominent feature of this impedance‐tuning method is to use an inductive‐tuning slot or a capacitive‐tuning slot, rather than the width of the grounding and feeding strips and the gap between the grounding and feeding strips, to get desirable impedance matching and bandwidth. © 2007 Wiley Periodicals, Inc.
