Abstract

Due to electrical connection between the array elements, standard baluns typically used in arrays of resonant dipoles are not effective for connected arrays. Therefore, a novel Printed Circuit Board (PCB) solution to avoid common-mode resonances, without resorting to active components or MMIC technology, is proposed in this paper. It consists in a loop-shaped component that rejects the common mode, allowing the design of connected arrays with X-pol levels lower than -15 dBs over a relative bandwidth that exceeds 30%. Simulated results obtained via Ansoft HFSS are presented for validation.
