Definitions
- the invention relates to an antenna for receiving and transmitting of electromagnetic microwaves of wavelengths ⁇ from a substrate layer made of low dielectric Material that has a conductive ground plane on one side has and the opposite side conductive in the form of Microstrip lines is structured.
- the scope of the invention extends ostensibly in the mobile and handheld technology sector within the spectral range between 890 MHz and 960 MHz or 1710 MHz and 1890 MHz by the component according to the invention into the corresponding end device and handheld technology is integrated.
- Known antenna solutions for the field of mobile radio applications are based on linear antenna designs in form of monopole arrangements in a shortened or unabridged version. These linear antennas are both externally mountable On-board antennas as well as directly with the end device coupled components known, as well as with different Indicative factor and efficiency, where these components in the azimuthal plane are only round strands are.
- Known flat antenna solutions are based on two-dimensional, dipole-like configurations, whose directional diagram is irregular and in connection with the the respective antenna carrier or antenna body have a significant radiation field deformation. The radiation properties related to the area of application are clear from those of the classic linear antennas inferior. There are also targeted blanking properties of the radiation diagram undetectable. Farther no solutions are known whose electromagnetic or radiation properties based on asymmetrical and open waveguide technology, especially microstrip technology, using foil conductors or foil-like guide surfaces can be achieved.
- the one shown in the patent DE 41 13 277 and azimuthal omnidirectional antenna configuration is only possible from a film as a mechanical structural support, said antenna component having an outside of the terminal equipment arranged head capacity is.
- the main radiation direction an inclination with respect to the elevation values of approx. (minus) -30 ° (angular degree), that is, a negative one Has elevation angle.
- a disadvantage of the known antenna configurations is hence that they are either in the azimuthal plane exclusively are omnidirectional or only within the negative Radiate elevation angle range.
- the object of the present invention is a system integrable Antenna component with the smallest possible area Expansion with azimuthal as possible one-sided Directionality, that is the preferred illumination of a Spatial hemisphere and a limited angular displacement of the elevation-related directivity within the positive To provide elevation angle range.
- the antenna according to the invention which can also be referred to as a foil radiator, is a modified ⁇ / 4 radiator which is short-circuited to ground on one side.
- the elongated conductor section which serves as a resonator, is made shorter than ⁇ ⁇ / 4.
- the resonator becomes inductive and the vibration condition is not met.
- an end capacitance is generated at the end of the resonator opposite the short-circuited side.
- This end capacitance is generated by at least one additional additional conductor section, one end of which connects to the end of the resonator opposite the short-circuited side and the other end of which forms an open circuit.
- the length of the additional further conductor sections determine the vibration condition and thus the resulting resonance frequency of the entire structure.
- Various embodiments of the conductor sections at the end of the resonator are conceivable for realizing a defined end capacitance for maintaining the vibration condition.
- the end capacitance can be realized by one or more lines of appropriate length, which do not necessarily have to run parallel to one another or to the resonator. All lines can also be designed in any curved shape and not just in a straight shape.
- the electrical properties of this antenna e.g. Quality, Impedance bandwidth, efficiency and gain depend on the size of the mechanical reduction (reduction) achieved, the width of the resonator, the distance between the resonator and the end capacitance sections, the effective permittivity constant, the substrate thickness or of the dielectric loss angle.
- an essential feature of the invention is that the resonators implemented in microstrip technology for receiving the microwaves are shorter than ⁇ ⁇ / 4, which enables a particularly compact and small construction to be achieved. Because the resonator length is chosen to be shorter than ⁇ ⁇ / 4, the oscillation condition is no longer met, as already explained. The required end capacities are realized by further line sections. An increase in the frequency bandwidth can be achieved by additional radiator elements through electromagnetic coupling. This is done by additional microstrip lines, which are arranged at certain distances from the resonator and its end capacitors.
- resonators can be arranged spatially nested in one another and matched to the required frequency bands.
- the individual antennas do not have to be in one plane but can also be arranged in layers one above the other. It is also possible that several antenna arrangements are provided per layer, so that more than two different frequency bands can be operated. This makes it possible for a mobile radio telephone to be able to communicate with different mobile radio networks.

- FIG. 8 shows antennas in which the frequency bandwidth the antenna through electromagnetic coupling with additional conductor elements, which on the same dielectric carrier substrate are arranged, is adjusted or enlarged.
- the antenna according to FIG. 8 corresponds in its basic structure to the antenna according to FIG. 3, a U-shaped conductor section 19, 20, 21 with its one leg 21 in the gap between the resonator conductor section 3 and the final capacity. Head section 2 engages.
