An approach to the design of a three-beam linearly-polarized microstrip antenna arrays has been proposed. The presented antenna arrays feature one broadside beam and two symmetrically scanned beams with respect to boresight direction generated with the use of a 3 × 3 Butler matrix as a feeding network. Such a Butler matrix allows to obtain equal power split and 0° −120°, and +120° differential phases at its outputs. The proposed concept has been experimentally verified by development and measurements of a three-element linear antenna array with uniform amplitude taper as well as a five-element linear antenna array with reduced sidelobe level, both operating at 2.5 GHz.
