Definitions
- the present invention relates to a planar antenna from at least one radiator element, which with a Coplanar line is coupled, the radiator element and the coplanar line on the same side of one Substrate.
- planar antenna is from T. Becks, D. Heberling, S. Pan and I. Wolff, "Planar radiator structures with coplanar feeding ", ITG technical report 128 of the ITG conference April 12-15, 1994 in Dresden, pp. 265-270.
- the planar antenna described in this article exists consisting of two slot radiators connected via slot lines with one coplanar feed line are coupled.
- a planar antenna used as a group antenna from a variety consists of radiator elements, is one with all radiator elements coupled, very complex dining network required.
- Such a feed network can be coplanar Barely realize feed lines.
- the invention is therefore based on the object of a planar Specify antenna of the type mentioned, each of which Provide the radiator element with such a feed line which makes it possible for a group antenna to be a complex one To implement the dining network with as little effort as possible.
- the substrate side can be used with a variety of radiator elements design a complex dining network very easily.
- the feed line as a microstrip line the substrate side opposite the radiator element is applied, the ground surface of the radiator element acts as a shield from the feed line so that it does not parasitic radiation occurs. That is why the feed lines carry not worsening with a group antenna the cross polarization properties of the antenna.
- the transition from a microstrip line to one another line type one connected to the antenna Cable can be implemented with little effort.
- the length of the coplanar line and the length of the section overlapping with it the microstrip line so chosen that a desired Coupling between the two lines is set.
- the radiator element can be used as a slit radiator or be designed as a coplanar line element.
- FIG. 1 shows a section of a substrate 1, on the top of which there is a planar antenna is applied from two slot radiators 2 and 3.
- This Both slot radiators 2 and 3 are via slot lines 4 and 5 with a shorted section of a coplanar line 6 coupled.
- On the underside of the substrate, that is the substrate side opposite the radiator elements a microstrip line 7, which as a feed line for the radiator elements 2 and 3 are used.
- the microstrip line 7 runs in sections below the short-circuited Coplanar line 6, so that an electromagnetic between them Coupling exists.
- the length of the coplanar line 6 and the length of the section covering the coplanar line the microstrip line 7 depends on the degree of coupling between the two lines. So you become this Choose both line lengths so that a desired one Coupling between the feed line 7 and the radiator elements 2 and 3 sets.
- the coplanar line can be used 6 also coupled with only one radiator element be.
- a microstrip line 7 as feed line, only proves to be particularly advantageous if the entire planar antenna is made up of a variety of There are radiator elements of the type described. Then can namely the microstrip lines of all radiator elements in a very simple way to a common dining network be summarized.
- the radiator element is a coplanar line element 8, which is applied to the top of a substrate 9.
- This coplanar line element 8 has a short-circuited Section of a coplanar line 10, which as already described in connection with Figure 1, in the same Way with a microstrip line 11 on the back of the substrate 9 is coupled.
- the one belonging to the coplanar line Metallization forms the ground area for the microstrip line.
