問題があった。Conventionally, the above-mentioned shared antennas include those shown in FIGS. 1 to 3. Both of these are intended to prevent UHF radio waves from being carried by the VHF receiving element to prevent the influence of the VI (F receiving element) on UHF reception. However, the one shown in FIG. VH
F-receiving folded dipole antenna 10 is provided with an auxiliary element 2.2.2.2 having the length of the first-order line 1a and the second-order line lb, and the above-mentioned specific U) IP radio wave. Near the frequency, the folded dipole outside of the auxiliary elements 2, 2...
Since HF radio waves become difficult to propagate, both IJ and ■ work well, but as mentioned above, they are quite far from my specific U HF radio waves.
There was a problem that the function did not work well at the high frequency, and the frequency bandwidth became narrow.Furthermore, since the auxiliary element 2. The one in Figure 2 used a lumped constant circuit 3 instead of the auxiliary elements 2, 2, and had the same problem as in Figure 1. The one in Figure 3 used UHF
, VHF are both configured with 4.5 dipole antennas, and VH
A capacitor 6 is connected between the feeding points of the dipole antenna 5 for F, and the value of the capacitor 6 is appropriately selected.
Short-circuit a and 5b and use them to receive UHF radio waves.
It's something new. ``The coil 7 that is parallel to the capacitor 6 is a loading coil. However, this antenna has a narrow bandwidth and requires a filter 8 and a matching device 9 and 10 as shown in Figure 3(b), making the circuit difficult. The problem was that it was complicated.

それぞれ出力端子とした構成である。Therefore, in the present invention, a dipole antenna for UHF band reception and a folded dipole antenna for VHF band reception are arranged facing each other at a predetermined interval, and the two feeding points of the dipole antenna and the folded dipole antenna of the folded dipole antenna are connected to each other. The two feed points are connected through two series circuits consisting of a capacitor with a value that blocks the VHF band signal, and a coil with a value that slightly delays the phase of the UH'F band signal and somewhat reduces the amplitude. The configuration is such that the connection points between the capacitor and the coil of the measurement array circuit are used as output terminals.

ルアンテナと。With this configuration, it is possible to prevent UHF radio waves from riding on the folded dipole antenna for the following reason. In other words, due to mutual induction with the UHF receiving dipole antenna, when U i (F radio waves are carried on the UHF receiving dipole antenna, the UHF radio waves are returned for VHF reception with a slight phase delay and a slight decrease in amplitude.) Rides on a dipole antenna.At this time, the phase is slightly delayed by the coil,
The UHF radio waves whose amplitude has been made somewhat smaller are VHF.
Reception) [Monday] The signal is supplied to the reverse dipole antenna in opposite phase. The series circuit supplies V in opposite phase.
This is because the feed points of the folded dipole antenna for VHF reception and the dipole antenna for UHF reception are cross-connected. Therefore, the UHF radio waves riding on the folded dipole antenna for VHF reception are canceled and have a negative effect on UHF reception. It is possible to realize a wideband U and V shared antenna without giving any additional energy to the antenna.Furthermore, it can be used as a folded dipole antenna for VHF reception.

2 also has UHF radio waves. This UHF radio wave is
The phase of the UHF radio wave carried on the receiving dipole antenna 18 is slightly delayed, and its amplitude is also slightly smaller. Therefore, the U HF of the opposite phase with the phase delayed by the coils 26a and 26b and the amplitude slightly reduced is applied to the feed point 20a side from the feed point 22b side and to the feed point 20b side from the feed point 22a side. The J wave is supplied and the U rides on the folded dipole 12 for HF reception.
HF radio waves are canceled. Therefore, UHF radio waves can be received well.

There is a gain of about 1 dB near the lowest frequency of the HF band, about 2.5 dB near the same center frequency, and about 0.2 dB near the highest frequency, and a higher gain can be obtained than when using the UHF dipole antenna 18 alone. Furthermore, Fig. 7 shows the gain-frequency characteristic diagram of this shared antenna in the VHF band.
