Abstract. Antennas with a mirror in the form of a parabolic cylinder: a multi-beam antenna with a planar three-mirror beam-forming system, as well as hybrid antennas with sparse linear feed arrays in E and H plane are investigated in a wide frequency band using a numerical experiment based on finite element methods and finite differences in the time domain. It is shown that the scanning sector of a multi-beam antenna in terms of the gain drop of -3 dB is more than 700, and the scanning sector of a hybrid antenna with a linear feed array in the E-plane is more than 270. In this case, the efficiency of the hybrid antenna with a linear feed in-phase array in the H-plane is more than 0.7 in the 10% frequency band, and with the feed in-phase array in the E-plane - more than 0.82 in the 24% frequency band.
Key words: parabolic cylinder, multi-beam antenna, hybrid mirror antenna, wide frequency band.
