Experimental Analysis of Quasi-Yagi Antenna Shapes

In this work, a broadband quasi-Yagi antenna is presented and its shape design is changed to analyse new characteristics and properties for wireless communications. This microstrip-fed antenna is designed in five different shape versions: dipole driver, patch driver, meander driver, log-periodic director array, and multi-director array. Details of the proposed designs and measured results of input return loss and radiation pattern are presented and discussed. In addition, a technique using a microwave link to measure the radiation pattern is explored, showing good radiation characteristic of the elements in a real environment.
