Embodiment Construction

[0023] The most notable feature of the present invention is that a single circuit has non-radiating dielectric waveguides of different sizes, each size of waveguide producing a corresponding frequency. Another feature is that there are spacers of different heights between the two plates to allow each of the different non-radiating dielectric waveguides to fit properly. Doing this allows us to handle more than one frequency in a single circuit.

[0024] It will be helpful to understand the objects, features and advantages of the invention to study the embodiments of the invention with reference to the accompanying drawings. Figure 4 A non-radiating dielectric waveguide having the features described above is shown. As can be seen in this figure, the stacked metal plates (10, 11) allow a variety of spacers between them, so that a variety of non-radiating dielectric waveguides (20, 21) of different sizes can be inserted between the metal plates so that different frequencies can...

Abstract

A non-radiating dielectric waveguide circuit between two multilayer parallel metal plates. Due to the multiple layers, the circuit has spacers of different heights between the boards, so non-radiating dielectric waveguides of different sizes designed according to their frequency of use are all inserted into a single circuit. By utilizing the present invention, we are able to construct a superheterodyne receiver which has the property of being able to mix received waves by a local oscillator to produce an intermediate frequency. The amplitude can easily be increased by means of the intermediate frequency, thus improving the reception sensitivity.

Description

technical field [0001] The present invention relates to a non-radiative dielectric waveguide circuit capable of generating multiple frequencies, whereas conventional non-radiative dielectric waveguide circuits can only generate a single frequency. Background technique [0002] In the multimedia era, the transmission form of information content has changed from text to text plus graphics, and is currently developing towards the direction of including moving images. And the technology that utilizes moving images has been further improved to provide high resolution and detailed colors. Thus, computer communication has assumed the burden of delivering multimedia information. [0003] As a way to solve this problem, computer communication has been upgraded from T1 level to T3 level. However, this upgrade comes with some drawbacks; for example, it is an expensive form of communication since fiber optics are very expensive to build. In addition, in some places where there are al...
