Definitions
- the invention relates to an antenna for radiating high-frequency radio signals according to the preamble of the main claim.
- an antenna for radiating high-frequency radio signals From the publication "Investigations of antennas for an indoor wideband communication system at 60 GHz” Zimmermann, MMMCOM, Dresden 12-13.5. 1997 it is known to design antennas for the communication between a base station and several mobile stations in a closed space as a lens antenna
- the antenna is to establish radio connections in a system for high-bit data transmission in the frequency range of 60 GHz from a base station installed under the ceiling to several mobile stations located in a closed room.
- the high-frequency signal of the base station present at the input of an antenna is radiated into the room to be supplied with the aid of the antenna.
- the radiation pattern of the antenna enables uniform coverage of the entire room area at a defined working height.
- mobile stations are supplied with more transmission power at a greater distance than mobile stations located at short distances below the transmitting antenna.
- the signal directly perpendicular to the ground has a lower power level than the signal that is radiated against the boundary walls of the room.
- reflections due to multipath propagation should be avoided. Otherwise, individual waves overlap at the receiving location, so that depending on the phase position, bs can be canceled by interferences of the total field strength.
- the proposed antenna for radiating the high-frequency signal from the base station consists of a lenticular plexiglass shape, which is fed by a waveguide.
- the geometry of the outer shell of the lens is similar to that
- the radio signals emitted are linearly polarized. Due to the geometry of the outer shell of the lens, reflection losses occur in the transition between lens material and air. In addition, the antennas of the mobile subscribers must be aligned so that they receive the linearly polarized signals appropriately.
- the antenna according to the invention with the characterizing features of the main claim has the advantage over the fact that the inner shell of the dielectric lens has a geometry adapted to the space, while the outer shell consists of a hemisphere. This makes it easier to apply an anti-reflective layer and to avoid reflection losses when the lens material and air pass.
- a primary radiator consisting of a waveguide with a helical antenna
- lenses are possible to design with small ⁇ r in small dimensions. This makes it possible, for example, to manufacture the lens material from polyethylene. Such an advantage can also be achieved if the primary radiator is formed from a carbon conductor with a patch antenna.
- Circular polarization of the radio signals is advantageously achieved by using such primary radiators. As a result, it is no longer necessary for the antennas of the mobile stations to have a specific orientation.
- the use of radio signals with circular polarization also mitigates the effects of multipath propagation. This minimizes interference effects.
- the electrical lens is advantageously anti-reflective by suitable measures. For this purpose, a ⁇ / 4 layer made of a suitable dielectric is advantageously applied or achieved by means of scoring.
- FIG. 1 shows the communication system and FIG. 2 shows the antenna according to the invention.
- FIG. 1 shows a base station 1 and a plurality of mobile stations 2 which communicate with one another via radio signals.
- the mobile stations 2 are in a closed
- the radio signals emitted by the base station are shaped into a steel cone 5. It can be seen that the radiation cone is shaped in such a way that reflections on the wall 4 are avoided as far as possible.
- the transmission power is different within the radiation cone, it is higher in the cladding area of the cone in order to be able to supply more distant mobile stations with transmission power and is reduced in the middle of the radiation cone.
- FIG. 2 shows the antenna 6 according to the invention, which consists of a primary radiator 13 and a dielectric lens 12.
- the primary radiator 13 consists of a waveguide 7, on which a helical antenna 8 is attached.
- the primary radiator projects into the inner shell of the dielectric lens 12.
- the outer shell 10 of the dielectric lens 12 is hemispherical.
- the anti-reflective layer 11 is located on the hemispherical surface of the outer shell 10.
- the antenna of the base station consists of a primary radiator and the dielectric lens.
- the primary radiator 13 is excited directly by the waveguide, so that no transitions and additional interfaces are necessary.
- the primary radiator generates a 60 ° wide radiation diagram with circular polarization, which is shaped by the dielectric lens 12 to form the target diagram.
- the shape of the dielectric lens depends on the spatial geometry and can be adapted to any room situation. Since the outer and inner shell of the lens can be used for beam shaping, there are two degrees of freedom. In order to be able to implement the simple anti-reflection layer, it is necessary that the wavefronts of the
- the lens itself is made of a dielectric material that is easy to machine.
- As a ⁇ / 4 anti-reflection layer for the dielectric-air transition grooves are screwed symmetrically into the material of the lens. These grooves must be smaller than the wavelength in the substrate. With these grooves of suitable depth and in a suitable duty cycle, a simple anti-reflective layer is possible without additional layering. For example, with a duty cycle of 1: 1, grooves of 0.5 mm wide and 1 mm deep are cut into the lens. This avoids reflection losses and improves the efficiency of the antenna. In addition, the radiation characteristics of the antenna are smoothed.
