Abstract

See full text

Antenna structure (200) which finds particular utility in mobile stations and the electrical characteristics of which can be electrically modified. The radiating element (210) of the antenna or a part thereof is manufactured from a strongly magnetostrictive material. The antenna is equipped with at least one electromagnet (220) by means of which a magnetic field (.psi.) can be generated into the magnetostrictive material. This causes the radiating element to grow (.DELTA.l) in a certain direction, whereby the resonance frequency of the antenna will decrease. The antenna can be electrically adjusted without adding any component in the antenna itself, thereby making the adjustment reliable.
