Abstract

Internal antennas are widely used in mobile wireless communication devices like smart phones, which have been a major incentive of internal antenna research and design during the last decade, where new designs with wider frequency bands have been introduced; single-band devices have developed into multiband and multimode terminals. Although the average terminal size has decreased drastically, the internal antennas have been designed into standard solutions, to meet the new design requirements, taking into consideration the strict limitations set on the energy absorbed by the users of mobile devices. In this paper, a model for frequency tunable ferrite-based Inverted F Antenna is proposed by altering the permeability of the ferrite material.
