The present invention will be described according to the accompanying drawing of representing example of the present invention below.
At first the principle to this example describes.About as described in the paragraph of prior art, existing antenna as unipole antenna, exerts an influence to antenna performances such as direction gains as the vehicle body of conductor ground plate under situation about being provided with near the conductor ground plate as top.The present invention utilizes the influence of this conductor ground plate to antenna conversely, and it is non-directional to realize that directivity is become, and improves directive gain, can obtain the antenna of high selectivity.
Example 1
Fig. 1 is the general structure chart of the antenna assembly of expression the present invention the 1st example.That is Fig. 1 (a) constitutes antenna element 101 with the linear conductor with two places bendings, and current feed terminal 102 is set on the assigned position of this antenna element 101, and with the antenna assembly of an end 103 ground connection.And Fig. 1 (b) constitutes antenna element 104 with the linear conductor with 4 places bendings, and current feed terminal 102 is set on the assigned position of this antenna element 104, and with the antenna assembly of an end 103 ground connection.The antenna assembly of this example can reduce to be provided with area owing to like this antenna element of unipole antenna is made the shape of bending.
Fig. 2 is the simple structure chart with the example that disposes with the close conductor ground plate of the antenna assembly of top described same structure.That is to say, Fig. 2 (a) constitutes antenna element 201 with the linear conductor with the bending of 2 places, with this antenna element 201 and the 205 close configurations of conductor ground plate, make the latter parallel with antenna plane, and current feed terminal 202 is set, on the assigned position of antenna element 201 with the antenna assembly of end 203 ground connection on conductor ground plate 205.And Fig. 2 (b) constitutes antenna element 204 with the linear conductor with the bending of 4 places, with this antenna element 204 and the 205 close configurations of conductor ground plate, make the latter parallel with antenna plane, and current feed terminal 202 is set, on the assigned position of antenna element 204 with the antenna assembly of end 203 ground connection on conductor ground plate 205.Like this, the antenna assembly of this example can reduce to be provided with area, owing to the antenna assembly of above-mentioned the 1st example and the 205 close configurations of conductor ground plate, make the latter parallel with antenna plane, directive gain is improved simultaneously.And the number in the bending place of antenna element also is not limited to above-mentioned illustrative number.This point for example described below too.
The object lesson of the antenna of Fig. 2 (a) is shown in Figure 85.In Figure 85, antenna element 8501 and the arranged spaced of conductor ground plate 8504 that the linear conductor of bending is arranged in two places with regulation, make the latter parallel with antenna plane, an end of antenna element 8501 be connected in be provided with the end of conductive plate 8503 conductor ground plate 8504 approximate vertical, that antenna ground is used.Here, the area that makes the area on the plane that antenna element 8501 forms and conductor ground plate 8504 about equally.In the centre of antenna element 8501 current feed department 8502 is set again.
Conductive plate 8503 is compared with the width of antenna element 8501 has sufficient width, that is has and make the width that is disappeared when the practicality by the reactance influence of the tuned frequency of antenna element 8501 decision.Therefore work as ground connection.Be coupled with antenna element 8501 if width is little, the whole antenna element that becomes, different with antenna element of the present invention.For example under wavelength was 940 millimeters situation, antenna element 8501 its total lengths were 220 millimeters, and 2 millimeters of width can be done compactly.Here, the mutual inclination of face of antenna plane and conductor ground plate is also passable, so long as produce the scope of effective potential difference between antenna element and ground plate.And under the situation of the area big (for example 4 times) on the area ratio antenna plane of conductor ground plate, identical for the vertically polarized wave gain, for horizontal polarized wave gain turn down then.
Different as for the antenna of saying this example and existing antenna, for example existing inverse F antenna, if make antenna element and ground plate near decreased performance, antenna assembly of the present invention then performance improves on the contrary.
The impedance operator of the antenna of Figure 85 and VSWR characteristic are shown in Figure 86.And the directive gain characteristic is shown in Figure 87.Shown in Figure 87, the antenna of Figure 85 demonstrates for vertically polarized wave and is roughly circular directivity.
Also have, the shape of antenna element and number of antenna elements are in this example certainly without limits.
Be spaced apart the then better more than 1/40 of wavelength between conductor ground plate and the antenna element again.
