On the top surface of conductive ground plate, first holder having first antenna element, second holder having second antenna element, and support having parasitic antenna element are provided such that holders and support confront each other. Respective intermediate sections of antenna elements are folded to shape like "square C" in plural times, so that antenna is formed. The foregoing construction allows low-profiling and downsizing antennas to be used in mobile radio devices.
