Abstract
A circuit with non-radiative dielectric waveguides held between two parallel metal plates which are multi-layered. Since the circuit has different heights of spacers between the plates owing to multiple layers, different sizes of non-radiative dielectric waveguides that are designed according to their using frequencies, are all inserted into a single circuit. By use of the present invention, we are capable of constructing a super-heterodyne receiver, which has the characteristic of mixing received waves through a local oscillator to produce an intermediate frequency. With the intermediate frequency, it is a lot easier to enhance amplitude and consequently reception sensitivity is improved.
Claims6
