Pattern Synthesis of Rotated-type Conformal Array Antenna Using Enhanced Adaptive Genetic Algorithm

Sector Synthesis of Antenna Array Using Genetic Algorithm

This paper introduces a new application of genetic algorithm (GA) in dynamic sector synthesis of antenna array for mobile base transceiver station (BTS). The basic objective is to have narrow beam widths in heavy handoff areas and wider beam widths in areas with low traffic density. By predefining the beam widths and thus the beams of each sector, optimal sectoring can be achieved using GA at d...

Phase only pattern synthesis for antenna array using genetic algorithm for radar application

The present paper describes the phase only pattern synthesis for the active phased array antenna using genetic algorithm. The phase only synthesis is required to broaden and shape the beam in transmit mode of operation where all elements are fed through the saturated power of transmit/receive modules (TRM). This technique is very useful in multifunctional radar application where broadened beam ...

Adaptive Detection and Estimation Using a Conformal Array Antenna

Synthesis of Antenna Array by Complex-valued Genetic Algorithm

The synthesis of the radiation pattern of linear antenna arrays is an interesting problem in radiating systems. A complex-valued genetic algorithm (GA) for optimization of beam forming in linear array antennas is presented in this paper. Unlike conventional GA using binary coding, this method directly represents the array excitation weighting vectors as complex number chromosomes and improves g...

Circularly Polarized Circular Slot Antenna Array Using Sequentially Rotated Feed Network

This paper presents the design, simulation, and measurement of two low-cost broadband circularly polarized (CP) printed antennas: a single element and an array at C band. The proposed single element antenna is excited by an L-shaped strip with a tapered end, located along the circular-slot diagonal line in the back plane. From the array experimental results, the 3 dB axial ratio bandwidth can r...
