Wide Band Linear Printed Antenna Array with Low Sidelobe Cosecant Square-shaped Beam Pattern

A wide band, integrated linear printed antenna array with low sidelobe cosecant square-shaped beam pattern is presented. Array synthesis mainly about the wide shaped coverage, low ripple and sidelobe level (SLL) has been done using the modified least square method by matrix inversion. A printed dipole integrated with wideband balun has been chosen as the array element for wide bandwidth and goo...

Design and Fabrication of Plasma Array Antenna with Beam Forming

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...

Optimum Design of Conformal Array Antenna with a Shaped Radiation Pattern and Wideband Feeding Network

─ In the present work, a circular conformal array with wideband printed dipole antennas and wideband feeding network has been designed to obtain a fully constrained cosecant squared radiation pattern using particle swarm optimization (PSO) algorithm and mutual coupling compensation. Using the circular conformal design leads to a decrease of around 33% of the length of the array antenna compared...

Dual 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...
