Abstract
In accordance with the concepts, systems, methods and techniques described herein a tripole current loop radiating element is provided having three conductors disposed on a substrate with the three conductors being physically spaced apart from each other and arranged to be responsive to radio frequency (RF) signals at a desired frequency range. Each of the three conductors includes a ground via to couple the respective conductor to a ground plane and a signal via to receive RF signals from a single feed circuit. The feed circuit includes a signal port, and first, second and third antenna ports, with each of the antenna ports coupled to a respective one of the three conductors. The feed circuit can provide the RF signals to each of the three conductors having equal amplitudes and distributed with relative phases of 0°/120°/240° respectively (i.e., phase shifted by 120° from an adjacent conductor).
