Theoretical Analysis of Polarization Rotation angle in Dual Reflector Antenna
Because of special structure, a dual reflector antenna has beam rotation capability in azimuth and elevation directions. In this structure, the antenna beam can be placed in any point in the space by mechanical movement of twist reflector which it is the most important ability of the antenna. Due to the antenna structure, if the polarization of incident wave is linear, it is expected that the p...
متن کاملDual Polarization Synthesis and Optimization of Cylindrical Offset Reflector Antenna for Cosecant-squared Radiation Pattern
This paper presents the shaping optimization of an S-band cylindrical offset reflector antenna with cosecant-squared radiation pattern in elevation plane. The cross section of the antenna is mathematically modeled by a polynomial function and optimized by the genetic algorithm to obtain the desired pattern for both TE and TM polarizations. The physical optics method together with the uniform th...
متن کاملPrinted Square-shape UWB Antenna with Dual Band-Notched Characteristics
Ultra Wideband (UWB) is a new emerging and promising technology as it can accommodate higher data over a large bandwidth. we proposed a Printed Square-shape UWB Antenna With Dual Band-Notched Characteristics. A simple square patch antenna has been fed through a 50 Ω microstrip feedline .A rectangular notch has been etched on the ground plane to reject the interference of WIMAX Band (3GHZ-4.7GHZ...
متن کاملDual wideband printed dipole antenna with integrated balun
A printed dipole antenna with integrated balun is presented. The radiating structure is a two-element dipole with resonances at 900 and 1700 MHz, with the balun providing one extra resonance at each band. By co-designing the radiating element with a Marchand balun modified for dual-band operation, an antenna covering the cellular bands 824–960 and 1710–2170 MHz has been achieved. Measurements o...
متن کاملDesign of Dual Reflector Cassegrain Feed System Antenna
This paper introduces a Design of dual reflector Cassegrain feed system antenna with suitable design aspects like smaller reflector and sub reflector diameter for higher sub reflector efficiency, lower Cassegrain blockage losses and desired illumination taper. Design parameters are computed from the simple and explicit analytical formulas. Design example is represented to differentiate the effi...
