A Miniature Dielectric-Loaded Folded Half-Loop Antenna and Ground Plane Effects

A miniature dielectric-loaded folded half-loop antenna on a mobile terminal operating at 5.2 GHz to cover the IEEE802.11a wireless system is introduced. The length of the proposed antenna is reduced by 50% compared to the dielectric-loaded folded loop antenna in previous studies. The antenna's performance is not affected much by changing the size of the ground plane. The return loss and radiation patterns of the antenna are assessed using both a finite integration technique (FIT) simulation and experimental measurements.
