N2 - In this paper, a Ka-band frequency selector is proposed by innovatively combining a snake-shaped slow-wave waveguide slot antenna with a Luneburg lens antenna. Slow-wave structure is introduced into the waveguide slot antenna to realize one-dimensional wide-angle scanning. The Luneburg lens antenna receives incident waves from different angles of waveguide slot antennas and converges them on different positions at the edge of the lens. Thus, the separation and selection of frequencies are obtained in space. The simulated results show that in the frequency band of 27 to 34 GHz, the device obtains the beam scanning with the spatial coverages from -50° to 25° and achieves good impedance matching. There is an one-to-one correspondence between the focal point at the edge of Luneburg lens antenna and the operating frequency, which has the application potential for millimeter-wave high-resolution spectrum observation.
