Definitions
- the invention relates to a dual polarization dielectric resonator antenna.
- the invention also relates to a network antenna consisting of elementary antennas arranged in the form of N lines and M columns, each elementary antenna of the network antenna being a double polarization dielectric resonator antenna according to the invention.
- An application field of the antenna of the invention is to transmit / receive signals from a satellite to mobile platforms such as, for example, planes, trains, boats, etc.
- the antenna of the invention is intended to be used in phased array antennas.
- the phased array antennas use the principle of semi-electronic scanning in which a small fraction of the angular variation of the transmitted wave is effected by electronic scanning, the remainder of the variation being performed by mechanical means.
- a limitation of the sweep is due to the geometry of the pattern of the radiating element.
- Phase controlled array antennas have been developed that use planar microstrip antennas with printed dipoles.
- the gain of a planar microstrip antenna with printed dipoles decreases when the scanning angle deviates from the direction perpendicular to the axis of the dipoles. This results in a decrease in the equivalent isotropically radiated power for large scanning angles.
- Mechanical devices are then designed to tilt the structure of the antenna.
- the microstrip antennas are inherently low bandwidth because of the very high Q factor of the resonators. This is another disadvantage.
- the dual polarized dielectric resonator antenna of the invention does not have the disadvantages of the antennas mentioned above.
- the invention relates to a dual polarization antenna comprising:
- microstrip substrate having a first face covered with a metallization and a second face, opposed to the first face, covered with two microstrip lines having axes substantially perpendicular to each other, an etching being practiced in the metallization, the etching having a rectangle-shaped cross section having a large side and a small side the projection, on the second face, of the axis of symmetry of the rectangle which is parallel to the long side being substantially aligned with the axis of a first line of the two lines;
- a dielectric resonator having the shape of a cylinder of revolution fixed, substantially centered, on the etching made in the metallization, the axis of the first line and the axis of the second line having a point of intersection on the axis of the cylinder of revolution, a first end of the first line forming a first port of the antenna and a first end of the second line forming a second port of the antenna;
