Pattern Synthesis for Arbitrary Arrays Using an Adaptive Array Method

This paper presents a new pattern synthesis algorithm for arbitrary arrays based on adaptive array theory. With this algorithm, the designer can efficiently control both mainlobe shaping and sidelobe levels. The element weights optimize a weighted L2 norm between desired and achieved patterns. The values of the weighting function in the L2 norm, interpreted as imaginary jammers as in Olen and C...

Planar arrays synthesis for optimal wireless power transmission

This paper describes the synthesis method of uniformly excited unequally spaced planar array with maximum beam collection efficiency (BCE, i.e., the ratio between the power radiated over a target region and the whole transmitted power) using Particle Swarm Optimization (PSO) algorithm. Based on this method, feeding network of the arrays becomes simple and compact and is easy to implement. And h...

Power Divider with Arbitrary Power Ratio and Arbitrary Ripple Level Using Filter Synthesis Techniques

A novel type of power divider, featuring arbitrary power ratio and arbitrary ripple level, is proposed. This divider consists of a two-port filtering structure connected to a circulator and is straightforwardly designed using microwave filter synthesis techniques. An example is provided, with low-pass domain synthesis and experimental divider demonstration at the Xband, after low-pass to bandpa...

Pattern synthesis method for arbitrary arrays based on LCMV criterion - Electronics Letters

A pattern synthesis method for arbitrary arrays based on the linearly constrained minimum variance (LCMV) criterion is presented. Given mainlobe regions and an arbitrary sidelobe envelope, this algorithm searches the pattern with the lowest sidelobe levels. Its iteration coefficient is robust to synthesis conditions, and patterns with a flat top mainlobe can be obtained using phase-independent ...

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...
