Abstract
A multiple frequency dipole antenna is provided. The antenna includes a plurality of conductive traces on a substrate (flexible or rigid). One conductive trace comprises the radiating portion and includes a plurality of radiating arms asymmetrically arranged. The other conductive trace comprises the ground portion and includes a plurality of ground arms. Radio frequency power is supply using, for example, a coaxial cable feed. The outer conductor of the coaxial cable feed is attached ground portion (either substantially parallel or perpendicular to a portion of the ground arms. The central conductor of the cable traverses a gap between the radiating portion and ground portion and is coupled to the radiating portion distal from the radiating arms.
