Abstract
Antenna structure () which finds particular utility in mobile stations and the electrical characteristics of which can be electrically modified. The radiating element () of the antenna or a part thereof is manufactured from a strongly magnetostrictive material. The antenna is equipped with at least one electromagnet () by means of which a magnetic field (ψ) can be generated into the magnetostrictive material. This causes the radiating element to grow (Δl) 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.
