Antenna for a radio communication apparatus

An antenna equipment employing a chip inductor based antenna includes a multilayered miniaturized chip inductance element having an approximately lambda /4 wavelength which achieves a half-wave dipole antenna performance together with a ground having an approximately lambda /4 wavelength. In a preferred embodiment, the inductance element is formed of a plurality of thin sheets of insulating material carrying conductor segments which are connected through via-holes in the sheets to form a spiral inductance element within the stack of sheets. Direct connection avoids impedance matching circuit insertion loss and low-cost miniaturization with reduced antenna gain deterioration from surrounding conductors is provided for an effective miniature portable radio communication apparatus.
