In order to realize that the antenna can receive a plurality of different signals simultaneously, preferably, the utility model discloses an at isosceles trapezoid receiving bottom plate 4 a plurality of oscillator pieces of installation.
Wherein each of the dipole pieces is operable to receive a signal.

The utility model provides a oscillator piece can simultaneous working, but when oscillator piece simultaneous working, probably produce mutual interference between the signal of receipt. Therefore, in order to avoid mutual interference of signals received by different oscillator pieces, the utility model discloses the mounted position to oscillator piece is injectd. That is, the installation positions of the low-frequency oscillator piece, the high-frequency oscillator piece and the GPS oscillator piece 7 are determined by the number of oscillator pieces on the isosceles trapezoid receiving base 4 and the frequency of the signal received by each oscillator piece.
Because the GPS signal has strong anti-interference performance, the GPS oscillator piece 7 can be installed at any position of the isosceles trapezoid receiving base plate 4.

In addition, when the installation positions of the oscillator pieces are determined, the installation positions of the oscillator pieces are obtained by adjusting according to multiple experiments, for example, the signal ranges received by the oscillator pieces are determined, then the positions of the oscillator pieces are simulated through the experiments, the oscillator pieces are started to work simultaneously, the interference and isolation between the oscillator pieces are judged through the experiment results, and the installation position of each oscillator piece is determined until the minimum interference exists among the oscillator pieces.
As shown in fig. 2, in the antenna for receiving multiple signals provided in this embodiment, since the transmission base is an isosceles trapezoid, based on the above principle, the high-frequency oscillator pieces in this embodiment are respectively denoted as a first high-frequency oscillator piece 61, a second high-frequency oscillator piece 62, and a third high-frequency oscillator piece 63; and the low-frequency oscillator pieces are respectively marked as a first low-frequency oscillator piece 51 and a second low-frequency oscillator piece 52.
Specifically, the shape of the isosceles trapezoid receiving base plate 4 is isosceles trapezoid, and therefore, the isosceles trapezoid receiving base plate 4 includes an upper base, a lower base, a first waist and a second waist, wherein the first waist and the second waist are equal and symmetrical about the central axis of the isosceles trapezoid receiving base plate 4. The central axis of the isosceles trapezoid receiving base plate 4 is perpendicular to the median line of the isosceles trapezoid receiving base plate 4, and the intersection point of the central axis of the isosceles trapezoid receiving base plate 4 and the median line of the isosceles trapezoid receiving base plate 4 is the same as the intersection point of the diagonal lines of the isosceles trapezoid receiving base plate 4. That is, the first high-frequency oscillator piece 61 is attached to the middle point of the upper base of the isosceles trapezoid receiving base plate 4, and the second high-frequency oscillator piece 62 and the third high-frequency oscillator piece 63 are symmetrically attached to the middle point of the first waist and the middle point of the second waist of the isosceles trapezoid receiving base plate 4, respectively, with respect to the central axis of the isosceles trapezoid receiving base plate 4. The first low-frequency oscillator piece 51 and the second low-frequency oscillator piece 52 are respectively and symmetrically installed at two ends of the lower bottom of the isosceles trapezoid receiving base plate 4 by the central axis of the isosceles trapezoid receiving base plate 4.
Further, the isosceles trapezoid receiving base plate 4 is provided with a welding point at a corresponding position, and the low-frequency oscillator piece and the high-frequency oscillator piece are mounted on the isosceles trapezoid receiving base plate 4 in a welding manner.
In addition, since the signals received by the dipole pieces have different frequencies and different wavelengths, the size of each dipole piece is different, and the size is specifically set according to the received frequency and wavelength.
For example, the smaller the frequency of the low-frequency signal received by the low-frequency oscillator piece, the longer the wavelength of the low-frequency signal, and the larger the size of the low-frequency oscillator piece. Therefore, the size of each low-frequency oscillator piece is set according to the frequency and wavelength of the signal received by each low-frequency oscillator piece.
In addition, since the antenna device provided in this embodiment is provided with two low-frequency oscillator pieces, the frequency range of the signal received by each low-frequency oscillator piece in this embodiment is different in order to avoid the repetition of the signal received by the low-frequency oscillator piece. Since the first and second low- frequency oscillator pieces 51 and 52 receive different frequency ranges, the first and second low- frequency oscillator pieces 51 and 52 have different sizes. Similarly, the dimensions of the high-frequency oscillator piece are also set.
Preferably, in general, the lower the frequency of the signal received by the low-frequency oscillator piece, the longer the wavelength of the signal, the larger the size of the low-frequency oscillator piece is required. As shown in fig. 4, under the condition that the volume structure of the antenna is unchanged, that is, the size of the isosceles trapezoid radome is unchanged (generally, the size of the isosceles trapezoid radome is fixed, such as height), in order to ensure that the range of the signal received by the low frequency oscillator piece is wider, the present invention installs a copper sheet 10 on the first low frequency oscillator piece 51, and the copper sheet 10 and the first low frequency oscillator piece 51 form a standing wave effect, that is, the wavelength of the signal that can be received by the first low frequency oscillator piece 51 is lengthened, so that the frequency of the low frequency signal received by the first low frequency oscillator piece 51 is lower, and further the frequency range of the low frequency signal received by the first low frequency oscillator piece 51 is widened, and under the condition that the volume of the isosceles trapezoid radome is unchanged, that is, the size of the first low frequency oscillator piece 51 is within a reasonable range, so that the wavelength of the low frequency signal received by the first low frequency oscillator piece 51 is longer, the frequency range is wider. Similarly, the corresponding copper sheet 10 is also installed on the second low-frequency oscillator piece 52, so that when the size of the second low-frequency oscillator piece 52 is ensured to be within a reasonable range, the wavelength of the received low-frequency signal is longer.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
