Embodiment Construction

[0028] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, a large gap is generated at the central conduction band of the coplanar waveguide, which is the innovative coupling structure of this design. The quasi-TEM wave energy of the coplanar waveguide structure propagates in two conduction band slots, and the two conduction band slots are gradually coupled into the conduction band slots (outer) of the two sub-nodes, and the wide conduction band slots generated by the coupling structure are also gradually coupled to the conduction band slots (inner) of the two sub-nodes, the quasi-TEM wave is formed by the two The transmission in the conduction band slot becomes the transmission in the four conduction band slots of two sub-branch coplanar waveguides, thus forming a power...

Abstract

The invention discloses a grounding coplanar waveguide power distribution / synthesis network based on a coupling structure, is applied to the field of millimeter waves and sub-millimeter waves, and inorder to solve the problem that an existing power distribution / synthesis network cannot give consideration to broadband, low insertion loss and good phase consistency. According to the invention, twopaths of energy synthesis are formed in a back-to-back mode by adopting a grounding coupling coplanar waveguide one-to-two circuit structure. Signal energy is transmitted through the two conduction band gaps of the grounding coplanar waveguide, is divided into two parts through the coupling structure, and is finally subjected to back-to-back output power synthesis; compared with the prior art, thepower distribution / synthesis network has the characteristics of small structure, good heat dissipation, low insertion loss, wide frequency band and the like.

Description

technical field [0001] The invention belongs to the field of millimeter waves and submillimeter waves, and in particular relates to a broadband and high-efficiency on-chip power synthesis technology. Background technique [0002] Electromagnetic waves with a wavelength of 0.1 to 1 millimeter are called submillimeter waves, which are located in the wavelength range where microwaves and far-infrared waves overlap, so they have the characteristics of both spectra. Compared with microwaves in lower frequency bands, their characteristics are: 1. The spectrum range used is wide and the information capacity is large. 2. It is easy to realize narrow beam and high-gain antenna, so it has high resolution and good anti-interference. 3. Strong ability to penetrate plasma. 4. Large Doppler frequency shift, high speed measurement sensitivity. Submillimeter waves are of great significance in communication, radar, guidance, remote sensing technology, radio astronomy and spectroscopy. ...
