Abstract

This work presents the design and performance characteristics of a novel antenna array structure. The prototype is composed by three equal quasi-Yagi antennas 120° shifted, due to this new layout to allow the configuration of the radiation pattern, forming directional patterns with high directivity, and keeping the same performance as the isolated element has in band terms. The array was designed for working at 2.4 GHz and optimized to include 1.9 GHz, GSM-USA standard. The simulation and design optimization were done by a commercial software using MoM (moment method). There is an acceptable agreement between the simulation and measured results of return loss of the array.
