Abstract
An antenna comprises a feed port, a 1/2 wavelength radiator (20), and a double resonant transformer (10). The feed, port, having a signal feed portion (34) and a ground portion (44), is at a low impedance while the 1/2 wavelength radiator (20) has opposed high impedance ends (21 and 22). For transforming low impedance to high impedance, at two resonant frequencies, the double resonant transformer is coupled between the feed port and the 1/2 wavelength radiator.
