By combining and interleaving three modified binomial power distribution circuits (PDCs) with three two-way power combining circuits, a compact full horizontal plane coverage beam-switching beamformer is formed. While six switches are needed in the proposed BFN, a simplified prototype BFN without the switches is fabricated and tested for preliminary verification. Measured results agree well with those simulated. The proposed 1 \times 12 modified binomial power distribution circular beamformer possesses several advantages over conventional circular BFN designs, including compact size, single-layered structure, and a wide bandwidth up to 11.4% centered at 5.6 GHz. ? 2020 EurAAP. |
