Definitions
- the present invention relates to a flat microwave antenna for receiving or transmitting right and left circular polarization signals according to the principle of reciprocity of antennas, comprising on the one hand radiating elements juxtaposed, and comprising on the other hand at least one printed circuit board. by means of which radiating elements are supplied in phase from a common connection point because these lines are of equal length and arranged in a tree-like pattern.
- This invention finds its application in the field of reception of 12 gigahertz television signals retransmitted by means of satellites.
- This document describes a planar antenna consisting of a thick plate of dielectric material on which a printed network of supply lines is made, connected to dipoles.
- Each dipole forms a radiating element (transmitter or receiver) of the antenna, and is formed of two planar plots in the form of fans placed head to tail.
- Each of the faces of the thick dielectric plate is provided with one of the halves of each dipole.
- the dipole supply lines are made using the so-called “triplate” technology.
- a supply line is formed of a said first plate constituted by a first conductive tape produced on the first face of the thick dielectric plate, of a said second plate constituted by the thick dielectric plate itself same, and of a said third plate constituted by a second conductive tape placed opposite the first conductive tape on the second face of the dielectric plate.
- Each half of the dipole is connected to that of the two ribbons forming the lines, which is produced on the same face of the dielectric plate.
- the supply network is of the so-called "parallel" type, so that the dipoles are supplied in phase and that the supply path is the same length for each dipole.
- This supply network is of the type previously named "arborized”.
- the thick dielectric plate fitted with dipoles and supply networks is protected on each side by a foam plate.
- One side of the antenna thus formed is finally protected by a dielectric plate, while the other side is provided with a reflective metal plane (or ground plane).
- Such an antenna is not capable of receiving a circular polarization signal.
- the “triple plate” technology used in this document is an expensive technology since the quality of the antenna depends essentially on the quality of the dielectric forming the dielectric plate, and that a good quality dielectric constitutes the most expensive part the antenna.
- the object of the invention is to propose a more economical antenna.
- the invention also relates to such an antenna characterized in that there is added to it a depolarizing structure, chosen for example from a 3 dB phase shifter or else a depolarizing device of the known type with meanders so that, on one of the terminals There is a left circular polarization signal at the output of the system thus formed, while at the same time on the other output terminal of the thus formed system is a right circular polarization signal.
- a depolarizing structure chosen for example from a 3 dB phase shifter or else a depolarizing device of the known type with meanders so that, on one of the terminals There is a left circular polarization signal at the output of the system thus formed, while at the same time on the other output terminal of the thus formed system is a right circular polarization signal.
- FIG. 1 in perspective, an example of planar microwave antenna comprising a whole array of receiving elements in accordance with the invention
- Figure 2 a section showing the. arrangement of the supply networks
- FIGS. 3a and 3b two diagrams showing the installation of the depolarization device for obtaining the signals with right and left circular polarizations.
- Each of these two supply networks consists of a series of successive stages of combination of the signals received by each receiver element, according to a conventional geometric arrangement such as for example that shown in FIG. 1 of the United States patent. 'America No. 3,587,110 issued June 22, 1971 in the name of the transferee RCA Corporation. Recesses can be provided (see FIG. 2) in the layers adjacent to the plane of the supply networks so as to allow, in a balanced arrangement such as that of FIG. 4 of this same cited patent, the progression of the lines of these networks from each of the individual receiver elements of the antenna to the single output connection of each of the two networks, passing through the successive combination stages.
- a 3 dB hybrid coupler is provided at the output of the two supply networks, the single output connection of one of these networks being connected to an input. of the coupler and the single output connection of the other network to the other input, and the two outputs of this coupler supplying said signals with right or left circular polarization (see the diagram in FIG. 3a).
- obtaining signals with right or left circular polarization can be carried out not with a 3 dB hybrid coupler placed downstream of the antenna, at the output of the supply networks, but with a depolarizer device, of the known type. meandering for example, placed in front of the antenna as shown in the diagram in Figure 3b.
