Abstract
An antenna system for reception and transmission of radio frequency (RF) signals and a method for tuning the antenna system are provided. The antenna system includes a ground plane, a first element and a second element. The first element includes a driven unbalanced antenna element that resonates within at least one predetermined first frequency band to transmit and receive radio frequency (RF) signals modulated at one or more frequencies within the at least one predetermined first frequency band. The second element is non-resonating within the at least one predetermined first frequency band and is located within an antenna volume of the first element to create a partial loop response within the antenna volume of the first element by capacitively coupling to the first element when connected to the ground plane.
