“…It is worth mentioning that researchers have developed different kinds of monopulse antennas for radar applications [ 1 , 2 , 3 , 4 , 5 ]. In [ 6 , 7 , 8 ], the monopulse feed was designed by leveraging a dielectric lens. In [ 9 ], researchers investigated a monopulse reflector antenna operating at 35 GHz for missile applications.…”

This paper presents a design for a monopulse reflector antenna with asymmetric beamwidths for radar applications at the Ku band. The proposed design features a rectangular waveguide monopulse feed and a truncated parabolic reflector. An array of four open-ended rectangular waveguides were employed to realize a compact monopulse feed. The reflector is cut in the H plane of the feed producing a wider beam in the azimuth plane. This type of pattern is useful in applications such as projectile tracking and airport surveillance. The design parameters for optimum performances are chosen at all stages of the design. The design and analysis have been carried out using the commercial simulation tool CST Studio Suite 2022. The directivity of the sum, elevation difference and azimuth difference channels of the reflector antenna are 32.1, 28.1, and 26.4 dB at 14 GHz; 30.9, 29, and 27.3 dB at 15 GHz; 31.7, 29.6, and 27.6 dB at 16 GHz; 31.6, 29.9, and 27.8 dB at 17 GHz.

The lens antenna is one of favorable types of antenna at millimeter-wave frequencies since it is structurally simple and of small size. This paper presents a design of a high-performance 35GHz monopulse lens antenna with high aperture efficiency and low sidelobes for missile seeker applications. First, a lens is designed based on the antenna requirements. Next, a monopulse feed is designed utilizing tapered dielectric rods. For ease in the implementation of the monopulse comparator network, a 5-element configuration is adopted where the sum-channel element is separated from difference-channel elements. Finally the monopulse feed and the lens are combined to complete the antenna design. The designed antenna with a 16-wavelength diameter aperture has the sum-channel performance of 32.3dBi gain, 4.24° beamwidth,-28.4dB sidelobe level, and the difference-channel performance of 29.0dBi gain, 2.36° cross-over angle,-23.5dB sidelobe level, and null depth of greater than 40dB.
