Back-lobe reduction of printed folded dipole reflector antenna for Wi-Fi applications
2017 International Conference on Wireless Technologies, Embedded and Intelligent Systems (WITS)(2017)
摘要
In this work we investigate the back-lobe reduction of a sectoral antenna. The antenna is fed by a coaxial cable and presents a good impedance matching in the 2.4-2.48 GHz WI-FI band. It has 9 dBi of gain in the main lobe direction and most importantly, presents a very high front to back ratio (over 40 dB). The antenna is composed of a printed folded dipole coupled with a metallic plate placed behind the driven element at a distance of tenth the wavelength. The system is low cost and easy to manufacture.
