Design of a 26GHz base station phased array antenna element

A novel printed antenna array has been designed and simulated for the needs of a node antenna for point-to-multipoint, PMP, radio links, operating at 26GHz. The antenna array elements are derived from the concept of the Marconi-Franklin collinear array. Each array element is being fed by two parallel transmission lines via an under ground plane of approximately 3/spl lambda//sub 26GHz//2 /spl times/ 3/spl lambda//sub 26GHz//2 mm/sup 2/. Following extensive simulations the radiation pattern of each array element was extracted concluding in an almost 8dB directivity with a 75% efficiency.
