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

A planar antenna is presented as part of a Signal Identification System working at 1.06 GHz. The antenna presents a monopulse radiation pattern. Likewise, a scanning of the main beam direction is achieved in a ±45° azimuth coverage. A limited 3 dB

A circularly polarized slotted array antenna is presented. The array is fed by a circular waveguide propagating the TM01, to properly generate the required polarization. An omnidirectional azimuth radiation pattern is obtained, as well as a −10°/+

An analysis model of radial-line slot antennas (RLSAs) based on a simplified method of moments (MoM), with closed equations that represent the coupling inside the radial line and the coupling in the free space, was presented in [1]. In this paper, an

The authors propose the design of one radial line slot antenna with two simultaneous beams, one broadside beam and one conical beam. The antenna is a radial line slot antenna (RLSA), with the slots placed on the upper plate in concentric rings. The r

The scattering of conducting regular polyhedrons of resonant size is studied by means of the electrical field integral equation (EFIE) and the method of moments (MoM). Two models are generated for each polyhedron, a wire grid model and a triangular p

A synthesis method for circular-polarization radial-line slot antennas excited by four posts inside the radial line is presented. This excitation generates a rotational mode inside the waveguide, and the slots that radiate the field can be placed arr

In this paper the design of an antenna for a signal identification system which works at 1.06GHz is presented. The system requires reduced dimensions because this antenna must be placed on an airplane. The structure is based on a multi-layer configur
