Abstract
Antenna apparatus, and an associated methodology, for a multi-frequency-band-capable radio device, such as a quad-band mobile station. The antenna apparatus is formed from a three-dimensional rectilinear non-conductive dielectric antenna substrate, such as cube. An elongated radiation element is disposed over multiple surfaces of the antenna substrate. A T-shaped impedance matching element located at the end of the radiation element permits the antenna input impedance to be matched to a communications device. The length of the radiation element is selected to be substantially equal to a quarter wavelength of the lowest frequency band at which the antenna operates.
