Design and Analysis of a Silicon-Based Pattern Reconfigurable Antenna Employing an Active Element Pattern Method
Abstract: In this paper, a silicon-based radio frequency micro-electromechanical systems (RF MEMS) pattern reconfigurable antenna for a Ka-band application was designed, analyzed, fabricated, and measured. The proposed antenna can steer the beam among three radiating patterns (with main lobe directions of −20◦, 0◦, and +20◦ approximately) at 35 GHz by switching RF MEMS operating modes. The ante...
متن کاملAntenna Pattern Compensation in Multi-Channel Azimuth Reconstruction Algorithm
In this paper the influence on azimuth performance of the antenna pattern in multi-channel SAR reconstruction algorithm is analysed and different approaches of its compensation described. Both transmit and receive antenna patterns affect the signals and hence have influence on performance of the whole system. Consideration of antenna pattern in the processing should help to achieve better perfo...
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 کاملInfluence of Grating Parameters on the Field Enhancement of an Optical Antenna under Laser Irradiation
In this study, a new approach for simulation of electric field enhancement ofplane wave laser around optical antenna was used to convert free-propagating opticalradiation to localized energy. A tapered gold tip design as a novel geometry of opticalantenna is introduced and numerically analyzed based on particle swarm optimization(PSO) by solving the Maxwell equations wit...
متن کاملOn the design of a reflector antenna
We consider the problem of recovering a reflecting surface such that for a given point source of light the directions of the reflected rays cover a prescribed region of a far field sphere and the density of the distribution of the reflected rays is a function prescribed in advance, where the aperture of the incident ray cone is also prescribed in advance. Mathematically this problem requires on...
