Abstract

In this paper, the development of a small antenna that can tune by broadband or two or more bands is described. The concrete specification which this antenna should satisfy, is that VSWR becomes 2.5 or less in the UHF band (470-700 MHz) which one-segment broadcasting service of digital terrestrial TV broadcasting of Japan uses. Concretely, the method of separately setting up the tuner probe in L-shape probe feed PIFA (planar inverse F shape antenna) is tried. As a result, the control bias for the tuner probe need not be superimposed to the antenna feed point, and the convenience of the antenna has improved greatly.
