A compact flat reflector antenna that utilizes a meander‐line bow‐tie (MLBT) monopole as its primary radiator is described. The antenna radiates predominantly vertically polarized electromagnetic (EM) waves, and is suitable for application in a base station. The new antenna has a resonant input resistance of 50 Ω. The bandwidth of the antenna is 5.3% within a return loss of less than −9.5 dB. The directivity of the antenna is 8.4 dBi, and the half‐power beamwidth in the horizontal‐plane pattern is 94°. Since the reflector acts as a ground plane for the primary radiator, a balun is not required. © 1998 John Wiley & Sons, Inc. Microwave Opt Technol Lett 18: 319–320, 1998.
