In this letter, a novel beam-switching array, which uses four patch elements to generate two anti-symmetric-shaped patterns, is proposed. Beam shaping is introduced into this design to realize a flat response in its two beams ±45° covering regions with less than ±0.55 dB fluctuation. A synthesis process is derived in detail, and a prototype, including the array and a planar feeding structure, is built and tested. The measurement result agrees well with the simulated one, which verifies the validity of the synthesis algorithm.
