Compact directive parasitic element antenna for wireless communications systems
Résumé
This article presents a design of a new compact planar Yagi-Uda antenna with three parasitic element fed by coplanar waveguide (CPW). The antenna is realized on multi-layer substrate (FR4) with 1.58mm of thickness and a relative permittivity of 4.4. The antenna is intended to operate at the ISM band with an obtained realized gain of 6.7 dB and a 184 MHz of bandwidth. The design of the antenna is carried out using the commercial electromagnetic simulator CST Microwaves Studio. The measured results of the whole system satisfied the simulated performances.
