“…The dual-mode behaviour of a ferrite loaded dielectric resonator excited by a monopole has been previously investigated [4]. Two wrap-around open metal rings were used to introduce a third parasitic resonance, thus increasing the bandwidth and creating a tri-band antenna [5].…”

Previous studies have shown that monopoles loaded with material of equal permittivity and permeability values give increased bandwidth and radiation efficiency for a given size reduction. Positioning the monopole orthogonally to the head directs pattern nulls towards the head, which leads to low Specific Absorption Rates (SAR). Simulated results of the material loaded monopole showed dual-mode behaviour. In this paper, the simple monopole is translated into a compact antenna design suitable for mobile handsets. Metallic strips are printed on the material block to increase the number of modes and realise a small, quad-band, low-SAR handset antenna.
