Abstract
The invention provides an aperture suture array speed compensation method and aperture array curved coplanar waveguide. The aperture array curved coplanar waveguide functions in perforating on media substrate on which the longer aperture of the conventional curved coplanar waveguide is positioned to reduce its effective dielectric constant, so as to fasten the transmission speed of electromagnetic wave in the longer aperture and compensate space distance difference using the speed difference of electric waves in the two apertures, then the electromagnetic waves in the two apertures has same phase after passing the curve, and the signal is synchronously outputted. The method not only can reduce production process and process cost, but also keeps the volume of original circuit and is in favor of integration and miniaturization of the circuit. The method can be used in microwave circuit and microwave integrated circuit of various electronic equipments, and can be used for volume production in printed circuit technique.
Description
Technical field
The present invention relates to microwave technical field, is the crooked co-planar waveguide of a kind of hole slot array speed compensation method and hole slot array specifically.
Background technology
Co-planar waveguide has the connection in series-parallel of being easy to, low radiation, low chromatic dispersion and is convenient to advantages such as integrated, so be widely used in the monolithic integrated microwave circuit.But because coplanar waveguide structure comprises two slits as transmission path, when coplanar waveguide structure is crooked, the situation that two gap lengths do not wait will appear, so electromagnetic wave phase difference can occur by after two slits, it is no longer synchronous to show as two signals in the slit in time, thereby the phenomenon such as chromatic dispersion, broadening of bigger reflection of electromagnetic wave, radiation, signal occurs, be unfavorable for the transmission of energy, the integrality of signal also is damaged.Discontinuous coplanar waveguide structure commonly used has: warp architecture, T type structure, hierarchic structure etc.Electromagnetic wave transmits in these structures all above-mentioned phenomenon can occur, becomes the problem that researcher falls over each other to study so how these structures are improved.
In research process, the someone has proposed to set up at the two ends in knee the method for air bridges, and this method has obtained using widely in microwave circuits.Its principle is two floors of co-planar waveguide to be coupled together with air bridges at the two ends of discontinuous construction respectively to make that the electromagnetic wave phase place is identical, signal Synchronization.But because the air bridges of being set up and co-planar waveguide be or not same plane, so increased the operation of setting up air bridges on manufacture craft, cost is increase to some extent also, and the increase of volume causes integrated level to descend to some extent from integrated angle.
Summary of the invention
Purpose of the present invention just provides a kind of hole slot array speed compensation method and the crooked co-planar waveguide of hole slot array.The function of the crooked co-planar waveguide of this hole slot array be by the conventional bending co-planar waveguide than the dielectric substrate at place, slit crack on perforate reduce its effective dielectric constant, thereby accelerate than electromagnetic wave propagation speed in the slit crack, utilize the speed difference compensation space path length difference of electric wave in two slits, make electromagnetic wave homophase after in two slits through the knee, show as signal Synchronization output on time, thus avoid because of the electromagnetic wave in two slits and signal can not homophase with can not export problems such as caused reflection, radiation, chromatic dispersion, broadening synchronously.
Technical scheme of the present invention is as follows:
1. provide hole slot array velocity compensation type crooked co-planar waveguide:
The version of the crooked co-planar waveguide of hole slot array velocity compensation type comprises:

4) the asymmetric co-planar waveguide of various distortion of hole slot array velocity compensation class: the inboard gap structure of crooked co-planar waveguide is constant, the hole slot array structure and above-mentioned 1 of the outside on the slit), 2), 3) described in hole slot array structure identical, but the sweep of co-planar waveguide is different shape.(as becoming 90 ° of camber line shapes bending or the like) by 90 ° of right-angle bendings.
2. the hole slot array speed compensation method of crooked co-planar waveguide may further comprise the steps;
1) selection is used for the hole slot array structure of co-planar waveguide velocity compensation.
2) slit that discontinuous co-planar waveguide upper pathway is long is set to the hole crack structure.
Beneficial effect of the present invention; Design the hole slot array structure of co-planar waveguide according to actual demand, the proposition of this structure is exactly in order to solve the problem of above-mentioned discontinuous co-planar waveguide path length difference, its principle is by the medium on the slit, longer path of crooked co-planar waveguide being made pore-forming slot array structure, can reduce the effective dielectric constant on this path like this, thereby accelerate slit, outside electromagnetic wave propagation speed, make through the phase place on two paths after the warp architecture identically, it is synchronous that signal keeps in time.Experiment and software emulation result show that this structure can effectively be accelerated crooked co-planar waveguide than electromagnetic wave propagation speed in the slit crack, make two slit output electromagnetic wave homophases, signal Synchronization, and change its structural parameters, reach different compensation effects.Again because this structure is directly to do perforation at the place, slit, the outside of co-planar waveguide to handle, so this method not only can reduce production process with respect to the method for air bridges, reduce manufacturing cost, nor can increase the volume of primary circuit, help the integrated and miniaturization of circuit, can be used for also being suitable for the production in enormous quantities of printed circuit technique in the microwave circuit and microwave integrated circuit of various electronic equipments.
