Definitions

  • the present invention relates to a microwave directional coupler with four transmission lines, as well as a passive power distributor circuit produced in a similar manner.
  • a power distribution circuit with four transmission lines, passive, reciprocal and without loss, further constitutes a directional coupler if each of the accesses to the lines. transmission is suitable.
  • a directional coupler with very flat coupling published in the journal IEEE Transactions on Microwave Theory and Techniques, vol. MTT-26, n ° 2, February 1978, p.
  • GP Riblet offers for the adaptation of a coupler in triplate lines a set of four short-circuited quarter-wave sections or four open-circuit half-wave sections, located at a quarter wavelength coupler inputs (sections ⁇ / 4: see Figure 3 of the cited document; sections X / 2: see Figure 4 of this same document where these elements are further folded to make the coupler more compact; we can also refer Figures 3 and 5 of English Patent No. 1,582,285 filed by GP Riblet). In all cases, it should however be noted that this is an adaptation carried out outside the coupler.
  • a first object of the invention is to propose a directional coupler which is both compact and suitable over a frequency band greater than what is obtained with the previous embodiments.
  • the invention relates to a structure coupler such that it comprises, for the connection of transmission lines, four line sections of width less than that of the transmission lines and electrically connected in their central zone and, superimposed so symmetrical to these line sections to achieve capacitive coupling with them in four zones or, in an alternative embodiment, an electrical connection, a resonant ring of width substantially equal to that of the transmission lines and of average perimeter such as the frequency of resonance is located just below the bandwidth of the coupler.
  • Another object of the invention is to propose a passive power distributor circuit produced in a similar manner, with a structure also in accordance with the invention, and which, for this purpose, comprises n sections of transmission line of width less than that transmission lines and arranged radially between the end of these lines and the central zone common to these sections, as well as a ring of width close to that of the transmission lines and superimposed symmetrically on these line sections in zones located in the vicinity of the end thereof to perform capacitive coupling with them in these zones or, in an alternative embodiment, connected to the line sections in zones situated in the vicinity of the end thereof , so as to surround them symmetrically.
  • FIGS. 1 to 4 show, by way of nonlimiting examples, four distinct embodiments of the present invention.
  • the directional coupler described with reference to FIGS. 1 and 2 in two embodiments in triplate lines comprises on the one hand two sections of transmission lines 10b and 20b for the two-to-two connection of the opposite transmission lines 10a, 10c and 20a, 20c.
  • these two sections which are here perpendicular have a width less than that of the lines so as to constitute two sections of higher impedance, and are moreover electrically connected together in their central zone 40.
  • the coupler also comprises a resonant ring 30, here substantially equal (or less) in width than that of the transmission lines and superimposed symmetrically on the two line sections 10b and 20b (without electrical connection with them) to achieve with them a capacitive coupling in the four zones 11a, 21a, 11b, 21b where the ring and the two line sections are opposite.
  • the circumference of this ring is chosen such that its resonant frequency is just below the passband of the coupler.
  • the structure thus adapted using the principle of duality mentioned above is completely symmetrical, in the sense that, despite the presence of the electrical connection zone 40, there is no coupling between the elements 10a, 10b, 10c located on one axis and the elements 20a, 20b, 20c located on the other perpendicular axis, and this on about an octave since the line sections 10b, 20b and the ring 30 have inductive and capacitive behaviors which compensate each other very satisfactory on such a frequency band.
  • the line sections 10b and 20b are straight and the ring 30 is circular.
  • an optimization of the adaptation can be obtained by increasing the length of the line sections 10b and 20b by approximately 10% and by reducing the on the contrary, the average perimeter of the ring 30.
  • the line sections are now curvilinear, while remaining perpendicular in their central zone, and a square shape is adopted for the ring 30, by replacing the four arcs of circle composing this ring by the ropes which underlie them (one can also adopt only one of these two provisions); in this way, the ends of the sides of the square ring coincide with the zones of capacitive or galvanic coupling between this ring and the line sections.
  • the present invention is not limited to the previous exemplary embodiments, from which variants can be proposed without thereby departing from the scope of the invention.
  • the coupling between the ring and the line sections must be galvanic, which leads to an arrangement such that that of FIG. 3, in which the connection is now electrical between the ring 30 and the line sections 10b and 20b, the four zones 11a, 21a, 11b, 21b now being common to this ring and these sections line, and the average perimeter of the remaining ring such that its resonant frequency is located just below the passband of the coupler; this change occurs at the cost of a slight reduction in bandwidth.
  • the line sections in any of the embodiments proposed, a variable width, increasing or decreasing from one end to the other, for the purpose of impedance transformation.
  • a passive power distributor circuit here with five transmission lines 50a to 50e. As shown in Figure 4, these lines are distributed symmetrically and five sections of lines.
  • transmission 60a to 60e of width less than that of the lines to form sections of impedance greater than that of the lines, are arranged radially; between the end of the lines and the central connection area 80 common to these sections.
  • a ring 130 of width here substantially equal to or slightly less than that of the transmission lines is connected in the vicinity of their end to the line sections 60a to 60e in the zones 70a to 70e, so as to surround these sections symmetrically (l 'ring could also as previously be capacitive coupling with the line sections, always in areas located near the end thereof.
  • couplers described above can be implemented in other types of couplers, and in particular in impedance transformation couplers such as that described in the patent.
  • the invention is also not limited by the technological aspects of its production. Specific examples of implementation have been given in triplate lines or in microstrip, but the invention is also applicable in the case of so-called coplanar structures, or in the case of periodic transmission structures for monolithic microwave circuits, such as that described in English Patent No. 2,056,783, or in the case of structures made of localized elements.
