Abstract: A tightly coupled dipole array is an egg-crate configuration defined by a plurality of electrically connected antenna unit cells. At least one of the unit cells utilizes a short or conductive element that shorts the common mode resonance. Shorting the common mode resonance in an intentional manner removes instances of the common mode resonance. To achieve the shorting of the common mode resonance, a conductive element is connected with one of the dipole arms and connected to the outer conductor of the feed or a ground plane. This creates a grounding loop that pushes the resonance out of the band of interest.
