A methodology for realizing compact planar sector antennas was proposed. Two kinds of beams are used to reduce antenna thickness, and the antenna gains are equalized. A 10 sector antenna was designed with two 4-beam subarrays fed by planar Butler matrix circuit and two planar single-beam subarrays. The 4-beam subarray was designed and demonstrated to provide the designed radiation patterns and the overall gain dispersion. Wideband propagation characteristics were simulated in a metal-walled room model. This method can reduce the thickness of the sector antenna to about one-seventh that of the corresponding traditional 12 sector antenna configuration. The planar sector antenna suits portable terminals by offering superior portability.
