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, Dual Linearly Polarized Single-Layer Radial-Line Slot ... This letter proposes a novel dual linearly polarized single layer radial-line slot-array antenna (D-LPRLSA). The dual polarization is achieved arranging the slots in concentric ellipses and ... A reflection cancelling slot set in a linearly polarized ... A radial line slot antenna (RLSA) is a high-gain and high-efficiency planar antenna. Circularly polarized RLSA (CP-RLSA) has realized the highest antenna efficiency of 85 percent to 60 cm phi DBS antenna. A linearly polarized RLSA (LP-RLSA) is also attractive for applications of various subscriber radio systems. Dual Linearly Polarized Single-Layer Radial-Line Slot ...

Helical antenna - Wikipedia A helical antenna is an antenna consisting of one or more conducting wires wound in the form of a helix. In most cases, directional helical antennas are mounted over a ground plane, while omnidirectional designs may not be. The feed line is connected between the bottom of the helix and the ground ... For monofilar designs the radiation is linearly polarized parallel to the helix ...
