Abstract :
This paper presents concept of an ultrawide band penta-beam antenna array with stable coverage area. The proposed antenna array produces five narrow beams (HPBW <;14deg) for cellular MIMO coverage with hotspots. The antenna array consists of two sub-arrays which work at 1710-2170MHz and 2300-2690MHz, respectively. The 6 × 6 Butler matrixes together with two way power dividers are used to produce five beams in the azimuth plane. The additional power dividers and stagger array arrangement are used to reduce the cross-over and side lobe level.
