Radiation Control Using Dipole-type Antenna for PCB Handset Applications

This paper investigates the radiation features of typical Printed Circuit Board (PCB) antennas combined with a dipole-type structure. Driven by the application request, a pattern-reconfigured is proposed and experimentally verified. By taking advantage of PCB antenna radiation feature and working principle of the dipole element, we are showing that a simple antenna structure change could redirect the radiation pattern. The antenna is designed on 1.6 mm FR4 board at 2.4 GHz aiming for Internet of Thing (IOT) applications. The modified antenna remains good radiation performance in terms of efficiency and bandwidth, while antenna pattern or polarization have been well tailored to meet to specified application request.
