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 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...
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 کاملRay Tracing of CMP Antenna Array GPR System
There is much interest in vehicle mounted array GPR systems for landmine detection and work is being carried out on various national, because high speed array GPR systems can sweep a large area in a relatively short time to improve performance and efficiency. We developed the vehicle mounted stepped-frequency (SF) CMP antenna array GPR system. The system has three pairs of Vivaldi antennas that...
متن کاملUsing ray tracing to evaluate smart antenna system performance for wireless communications
This paper motivates the use of electromagnetic ray tracing for the study of smart antennas in Space Division Multiple Access (SDMA) systems. Whereas past ray tracing studies applied to the study of wireless communications systems have been conducted at low spatial resolution for cell-site design, this study makes use of high resolution data so that fast fading effects could be observed. Uplink...
