In this paper, we present a cylindrical shaped-re∞ector antenna which is spatially fed by an ofi-set linear feed array to form complex beam patterns. The linear feed array consists of twelve microstrip patch elements and forms a ∞at-topped beam pattern with a beam-width of §45 - in the azimuth plane. The vertical curve on the cylindrical re∞ector with the linear feed array is shaped to form a cosecant beam pattern within the range of i5 - to i25 - in the elevation plane. By using the proposed design procedure to form complex beam patterns, a hybrid antenna with a cylindrical re∞ector aperture of 140cm £ 50cm is designed to be operated within the IMT 2000 service band, and a prototype antenna is also fabricated. Its electrical performance is measured and compared with simulation results.
