(English Abstract)
In this paper, we introduce a novel feeding method for a broadband planar quasi-Yagi antenna (QYA) for terrestrial digital television (DTV) receiving. The balun between the balanced coplanar strip (CPS) line feeding the driver dipole and the unblanaced microstrip line is a rectangular patch inserted into the CPS line along the center of the CPS. The end of the balun is connected to the CPS line through a shorting pin. The effects of various geometrical parameters and balun on the antenna characteristics are examined. An antenna, as an design example for the proposed antenna, is designed for the operation in the frequency band of 470-806 MHz for terrestrial DTV.
