- W4200432079 abstract "A compact and highly isolated three-sector linear array is proposed targeting at point-to-point or point-to-multipoint data communication in Central Business District (CBD) and residential subdivision applications. It features wide bandwidth, high isolation among the units, low wind load, low manufacturing and installation costs within the 400-500 MHz band. The driving element of the array unit is a wideband high-efficiency electromagnetic structure (WHEMS) applied in combination with the metal rods as passive elements for isolation purposes. The parasitic rod, shared by the adjacent units, decouples the mutual coupling by reducing the distance, which realize not only the high isolation capability but also reduced size. The beamwidth and the front-to-back ratio of the antenna are controlled by the combined effect of the metal rods and the bent of the active element. The impedance bandwidth of the antenna is 380-670 MHz (55%), and the H-plane HPBW is more than 70° in the 380-520 MHz. The front-to-back ratio is more than 19 dB and the gain is 8.2±0.4 dBi in 400-500 MHz. The isolation is greater than 36dB with unit spacing less than 0.2λ in 380-670 MHz." @default.
