Abstract

A tuneable quad-band radio antenna device (1) for a radio communication terminal, said antenna device comprising a ground substrate (2), a dual-band antenna element comprising a first elongated antenna member (3), a second (4) elongated antenna member, which is shorter than said first member, and a ground connection (11,12) connecting said members to ground. An impedance switch device (20) is operable to change the impedance of said connection (11,12) for tuning the antenna element, such that in a first impedance setting (Z1,Z3) the antenna element is resonant to a first and a second radio frequency, and in a second impedance setting (Z2,Z4) the antenna element is resonant to a third and a fourth radio frequency which are frequency shifted from said first and second radio frequencies. <IMAGE>
