Design of a Wideband Monopulse Antenna Using Four Conical Helix Antennas
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 130mm × 150mm. The bandwidth (SWR < 2 dB) of the antenna is 21.3% with an operating frequency range of 2.7GHz–3.35 GHz. The maximum gain of the sum pattern is 17.4 dB, and the null depths of the di...
متن کاملCyclical Surfaces Created by a Conical Helix
The paper describes cyclical surfaces created by revolution of a circle about an edge of the trihedron of a conical helix that is moving evenly along the helix. This Euclidean metric transformation is composed from revolution about one of the coordinate axes and transformation of the righthanded coordinate system to the right-handed system of the moving trihedron in every point of the conical h...
متن کاملA Wideband Compact Planar Conical Loop Antenna
This paper reports the design of a wide band planar fed, planar conical loop Antenna. Parametric studies have been carried out to arrive at the optimum antenna dimensions to have a wide impedance bandwidth (VSWR<2). Experimental results confirmed the wide impedance bandwidth.
متن کاملTappered Spiral Helix Antenna
This paper presents the aspects related to the design and development of a tapered spiral helix antenna covering the frequency range 1.2-18GHz. It is a compact stateof-the-art circularly polarized antenna, which works over multi-octave frequency bandwidth (1.2-18 GHz).The antenna size has been reduced by 50 percent with respect to conventional spiral antenna used for same frequency band. Spiral...
متن کاملMonopole Antenna Radar Cross Section Reduction with Plasma Helix
In this paper, a new method for radar cross section reduction of a monopole antenna is proposed. In this method, a plasma helix like fluorescent bulbs is placed around the antenna element. The selected plasma parameter for this medium acts as an absorber without disturbing the antenna performance. The simulations show that radar cross section of simulated antenna is reduced in a wide frequency ...
