Study of frequency selective surface (FSS) resonator elements on a circular dielectric rod antenna for mobile communications

This paper reports on the development of antennas for mobile communications systems based on a dielectric rod antenna fed from a circular waveguide. The results presented are for a linearly polarised antenna with a partial frequency selective surface (FSS) cover and without an endcap. The complete system was modelled using the transmission line matrix (TLM) method. This allowed an accurate design to be achieved before committing to any hardware production. Good agreement between measured and modelled results has been observed. Clear beamforming by the addition of FSS elements has also been demonstrated
