It has been previously established that material loaded monopoles having equal permittivity and permeability values, give increased bandwidth and radiation efficiency for a given size reduction. Very low Specific Absorption Rates (SAR) have been obtained by orthogonally positioning the antenna towards the head. Recent results obtained from a TLM simulator indicate the antenna’s capability to operate in dual mode. In this present paper various designs are researched, in order to preserve and translate the antenna features into a more compact embedded version. A final design solution is presented with the addition of metal strips, confirming the realisation of a small, triple-band, low-SAR handset antenna.
