An electrode is formed on at least one surface of first and second surfaces of a dielectric film formed of resin to be capable of receiving or transmitting an electromagnetic wave in a terahertz band. A semiconductor device operable in the terahertz band is mounted on at least one surface of the first and second surfaces of the dielectric film to be electrically connected to the electrode. A portion of a support layer is formed on the first or second surface of the dielectric film, and a dielectric lens is supported by another portion of the support layer.

When configuring a film antenna for receiving a circular polarized wave, at least one loop antenna is formed on a transparent plastic film and, at the same time, a non-powered element constituted by a wire-shaped conductor independent from the antenna conductor configuring the loop is arranged near this loop antenna. The non-powered element arranged on the side of the loop antenna is configured by a first part and a second part. The first part is made close to the loop antenna in a substantially parallel state. When a monopole antenna is used in place of the loop antenna, by combining this with a wire-shaped conductor orthogonal to this, it becomes possible to receive a circular polarized wave by a configuration providing a power transfer part between the two. It is also possible to configure a composite antenna by mounting another antenna on the transparent plastic film. This antenna can be used as an antenna of a navigation system.

SOI MOSFETs are used for the transistors for switching of an antenna switch and yet harmonic distortion is significantly reduced. Capacitance elements are respectively added to either the respective drains or gates of the transistors comprising the through MOSFET group of reception branch of the antenna switch. This makes the voltage amplitude between source and gate and that between drain and gate different from each other. As a result, the voltage dependence of source-drain parasitic capacitance becomes asymmetric with respect to the polarity of voltage. This asymmetry property produces signal distortion having similar asymmetry property. Therefore, the following can be implemented by setting it so that it has the same amplitude as that of second-harmonic waves arising from the voltage dependence of substrate capacitance and a phase opposite to that of the same: second-order harmonic distortion can be canceled out and thus second-order harmonic distortion can be reduced.
