Definitions
- the invention relates to a radio antenna as a transmitting antenna or receiving antenna according to the preamble of claim 1 and a mobile radio system the preamble of claim 13.
- Radio frequencies for radio communication start in a frequency range of a few kHz.
- frequencies between 520 kHz and 1,605.5 kH in the shortwave range between 5.9 MHz and 26.1 MHz and in the ultra-shortwave range used between 87.5 MHz and 108 MHz.
- frequencies between 124 MHz and 790 MHz are used.
- Ultra-high frequency ranges are used, among other things, for mobile phones with analog Technology from 450 MHz to 465 MHz) and for digital GSM (Global System for Mobile Communication) from 890 MHz to 960 MHz and 1,710 MHz used up to 1.880 MHz.
- Cordless phones work in an overlying one Frequency range from 1,180 MHz to 1,900 MHz. These ultra high frequencies allow relatively small antennas to be used and guarantee one comparatively reliable connection for mobile communication.
- Directional microwave links currently use frequencies between 2 GHz to 40 GHz.
- Radio frequencies are scarce resources and all useful radio frequencies can be used are practically already occupied nowadays. There is a constant task thus in that these radio frequencies are only available to a limited extent through improvements in transmission techniques and through improvements the modulation techniques for the highest possible rate of information transmission to use better with good transmission quality.
- a mobile radio system comprises mobile stations in a generally known manner (MS, Mobile Station) as cell phones for participants.
- a mobile radio system also includes Base stations (BTS, Base Transceiver Station) in one each local area as a radio cell, with larger local areas in adjacent Radio cells are divided.
- the base stations handle radio communication with the Mobile stations.
- Multiple base stations (BTS) are each a base station control station (BSC, Base Station Controller) assigned to it are connected via a data transfer and the assigned base stations (BTS) control and coordinate.
- the data transfer can be done via Copper lines or by radio, in particular directional radio.
- BSC base station control stations
- MSC Mobile Switching Center
- the data transfer can also be done here via lines or by radio relay.
- the signal quality when sending and / or receiving can be conventional Antennas adversely affected by antenna noise, among other things be, since this is only partially selective and only with a certain sideband noise are operable. Among other things, this makes the previously required Protective distances cannot be reduced arbitrarily.
- An object of the invention is to use a simply constructed radio antenna Propose broadband antenna that has a large usable radio frequency range covers and highly accurate in the transmit and receive mode can be operated frequency-selectively. Another object of the invention is in proposing a cellular system using one Radio antenna.
- the first object has the features of claim 1 and the second Task solved with the features of claim 13.
- the radio antenna is a surface antenna that consists of a Carrier part, a coating attached to it and two coating feed lines consists.
- the carrier part consists of insulating material.
- the coating feed lines are at least two spaced apart electrical conductors made of electrically highly conductive material, which is an electrical Have connection to the coating in the intermediate distance.
- the coating leads are covered with other electromagnetic elements Connected resonant circuit, with the coating via the surface area of which can emit or receive electromagnetic waves are.
- the binder comprises for applying a uniform coating distilled water, which makes the individual components work well together be mixed.
- the sulfurized oil and possibly a leveling agent serve as Solution mediators and cause an even distribution of the individual Substances in the binder and good film formation of the coating material on the carrier part.
- the phenols or benzisothiazolinone contained in the binder the accumulation of particles even in small quantities.
- the casein is as To view the binder in the binder and causes the individual to accumulate Components within the binder.
- the urea is in the binder also used as a solubilizer and favors the uniform Distribution of the individual components.
- the basic substance comprises the main constituent of the binding agent accumulate the particles of the insulation agent.
- the dispersant makes it easier the dispersion and thus the even distribution of the binder together with the particles of the insulating agent in the basic substance.
- the admitted Graphite with its individual particles also attaches to that the binding agent binding binder. Together with the insulation agent a large number of the smallest electrical dipoles are thus formed evenly in the coating material and thus in the finished applied Coating are distributed.
- the arrangement provides a large number of coupled, smallest harmonic and aharmonic oscillators in the form of Dipoles. This results in a high degree of transmission and reception for electromagnetic Radiation in the entire usable radio frequency range of a few KHz to the GHz range with extremely high frequency selectivity.
- the radio antenna according to the invention surprisingly has a spherical radiation pattern without pronounced directivity. This too can lead to a reduction of the operating energy can be used. This leads to cell phones also advantageous to improve the electromagnetic compatibility, since a certain predetermined radiation power affects all spatial directions distributed and thus a concentration of radiation power on the Head area of a user is avoided.
- the radio antenna according to the invention can be advantageous in all radio systems and radio systems with the advantages mentioned above, such as in radio or television, because of the broadband and the high frequency selectivity practically across the entire bandwidth all usable radio frequencies can be covered. Adjustments to different Achievements can be easily done through dimensional adjustments become.
- the carrier part is simple and inexpensive from electrical insulating, stable plastic.
- the radio antenna or the carrier part can have different shapes have, because the antenna effect over a variety in the coating contained dipoles is effected.
- An active coating can then, depending on the circumstances be attached to one and / or both surface sides.
- one Planar antenna has a spherical radiation pattern. The possible radiation and reception power is essentially determined by the between area of the coating lying to the assigned coating feed lines given, whereby the layer thickness has a smaller influence, however, also to be strengthened for larger performances.
- the carrier part can be an integral part of a part Be outer wall of the housing, especially one made of plastic Mobile station housing, which is an advantageously compact structure and simple Manufacturing are possible. It is no longer necessary as before usual to protrude a rod antenna, for example from a cell phone housing to let.
- sulfated oils can be used as sulfurized oils for the coating Olive oil, sulfated sesame oil or sulfated palm oil can be used.
- sulfated castor oil is used is known as sulforicinate or as Turkish red oil. This is special well suited for its surfactant properties.
- the phenols are preferably carbonized by cracking manufactured phenols, which are particularly suitable for particle attachment exhibit.
- benzisothiazolinone should preferably be used.
- the diluent is an aromatic-based solvent and / or alcohol base and / or ester base and / or ketone base, e.g. B. Terpenes.
- the insulation is preferably an insulating Soot.
- This soot is advantageously already in the ground state with a very small particle size added. This will create an even distribution of the soot in the basic substance and thus overall the training favored a variety of electrical dipoles in the coating material.
- the coating material in a preferred embodiment contains a thixotropic agent.
- This thixotropic agent has the effect that the coating material has a viscous consistency, ie it is easy to spread while being applied to the carrier part, but is so tough when at rest that no drops or tears form on the surface. This makes it possible to apply the coating material to the carrier part with precise contours.
- the coating feed lines are copper foil tapes aligned in parallel and the coating is applied below or above the copper foil tapes for the purpose of establishing an electrical connection or these are embedded in the coating. An inductive and / or capacitive coupling is thus achieved in particular.
- a protective layer thereon to install This can be the last top layer of the coating be or consist of a protective film known per se. The antenna effect Such a cover is not affected by this.
