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.
