Uniform Circular Array Pattern Synthesis Using Second-Order Cone Programming

Here we formulate second-order cone programs (SOCPs) for synthesizing complex weights for far-field directional (single-point mainbeam) patterns for narrowband arrays. These formulations, while constructed here with the uniform circular array (UCA) in mind, are actually quite general in that they control the arbitrary-pol sidelobe level (SLL) and co-pol SNR loss relative to ideal by minimizing ...

Pattern Synthesis of Linear Array with Position and Position-Amplitude Control using Firefly Algorithm

It is well known that several methods are reported to design array antennas for the generation of radiation patterns. It is found that none of them are optimum. However, in the present work, a new swarm intelligence method Firefly algorithm is applied for their optimization. Both uniform and non-uniform arrays are considered. The power patterns are numerically computed for different arrays and ...

Phase-only Synthesis of Linear Microstrip Patch Antenna Array using Improved Local Search Particle Swarm Optimization

Antenna arrays have been used for various applications in wireless communications, Radar, satellite communications and mobile communications. Low sidelobe antenna arrays are need to be designed for increasing the efficiency of the communication systems. In this paper, an enhanced version of particle swarm optimization (PSO) known as improved local search particle swarm optimization (ILSPSO) is ...

Antenna array pattern synthesis via convex optimization

We show that a variety of antenna array pattern synthesis problems can be expressed as convex optimization problems, which can be (numerically) solved with great eeciency by recently developed interior-point methods. The synthesis problems involve arrays with arbitrary geometry and element directivity, constraints on far and near eld patterns over narrow or broad frequency bandwidth, and some i...

Sidelobe Level Reduction in Linear Array Pattern Synthesis Using Particle Swarm Optimization

The design of nonuniformly spaced linear array antennas using Particle Swarm Optimization method is considered. The purpose is to match a desired radiation pattern and improve the performance of these arrays in terms of sidelobe level. This performance criterion determines how well the system is suitable for wireless communication applications and interference reduction. Two approaches are cons...
