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 s 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.
