Constant flux illumination of square cells for MM-wave wireless communications

Cosecant squared cell illumination may contribute to enhance system performance in MM-wave wireless communication systems. Previously proposed axial symmetric dielectric lens antennas produce a most useful constant flux circular footprint, but they fail to cover the regions near the vertices of square cells. This paper presents a simplified procedure to design a 3D dielectric lens that produces a constant-flux square foot print, intended for the illumination of square or rectangular cells. Calculated and measured antenna performance is presented not only in terms of radiation pattern, but also in terms of coverage, and time dispersion
