Abstract-This paper shows the design of a radial line slot antenna for Space Debris Radar Applications. The monopulse antenna has two beams, sum and difference, and requires an amplitude and phase receiver for detection of the azimuth and elevation direction of arrival. The antenna is circular polarized, and this paper focus on the design of the receiver antenna. The paper shows the optimization process of the position and length of slots in the central frequency of 94 GHz and a first analysis of the feeding network. This design will be tested with the fabrication of a prototype Index Terms-radial line slot antenna, monopulse, antenna synthesis, radar, space debris.

“…Using a reflector antenna, four horn antennas as feed network and waveguide monopulse comparator has been a common way for designing this radar for years [1]. However, large size and difficulty in instruction led to applying other antennas such as microstrip and SIW antennas in designing monopulse radar [2][3][4][5]. A low-cost K-band microstrip patch monopulse antenna was designed by Jackson [2].…”

Abstract-A novel S-band monopulse antenna with four conical helix antennas on a microstrip substrate comparator is designed, fabricated and measured. Conical helix antenna height is 3λ, and comparator size is 130 mm × 150 mm. The bandwidth (SWR < 2 dB) of the antenna is 21.3% with an operating frequency range of 2.7 GHz-3.35 GHz. The maximum gain of the sum pattern is 17.4 dB, and the null depths of the difference pattern are less than −30 dB.

“…The two-layer type uses incoming wave and the one-layer type uses outgoing wave for exciting the slots. Figure 2 shows two types of adaptors that are used in RLSA antennas as feeding structures [14][15][16][17][18]. The conical probe adaptor has wider application than the conventional type because of its wide bandwidth and thickness of RLSA.…”
