れる無指向性アンテナをもつアンテナ装置に関するもの
である。[Detailed Description of the Invention] [Industrial Application Field] This invention has an omnidirectional antenna that is used for communication and direction finding assistance in combination with a direction finding antenna in the VHF-UHF-HF band. This invention relates to an antenna device.
この種の無指向性アンテナは、一般に、アンテナ支柱の

各アンテナ素子の受信出力を合成して得られる疑似的な
蕉指向性出力を無指向性アンテナの出力として代用する
方法が採られている。This type of omnidirectional antenna is generally constructed by placing a discone antenna or dipole antenna on the top of the antenna column, or by combining the receiving outputs of each antenna element of the direction-finding antenna. A method has been adopted in which the directional output of the antenna is substituted for the output of an omnidirectional antenna.
ブラ一方式方向探知装置においてはＦＭ変調キャンセル
用と通信音受信用とに使用する無指向性アンテナとして
用ちれている。In the BRA one-way direction finding device, it is used as an omnidirectional antenna for canceling FM modulation and for receiving communication sound.

その各方向探知用アンテナと岨み合わせて各１対とし、
それぞれ異なる支柱に装備して分散配置する方法が採ら
れている。However, in cases where the frequency band used for radio direction finding is very wide, multiple direction finding antennas are provided to share appropriate bands, and direction finding auxiliary antennas are also used.
Combined with each direction detection antenna, one pair each,
The method used is to equip each on different pillars and distribute them.

う不都合があるため、各アンテナを１つ支柱に縦列状態
に配置して、この不都合を解消させたものの出現が期待
されているという問題点がある。As mentioned above, if the bands are divided and arranged, mutual interference between the seven branch offices will result in the inability to receive reception or direction detection, so it is necessary to distribute the networks to the extent that this can be avoided. A considerably large site is required, and there is the disadvantage that it cannot be installed on narrow sites, on ships, on rooftops, etc., so each antenna was arranged in tandem on one support, which solved this problem. The problem is that it is expected to appear.

信出力が得られるようにして上記の解決したものの出現
が期待されているという問題点がある。To arrange these antennas in tandem on one column, one omnidirectional antenna placed at the top provides an omnidirectional antenna output that covers the entire frequency band, and this is used for each direction-finding antenna. However, in this case, there is a problem that reception sensitivity is insufficient in low frequency bands, and on the other hand, it is possible to combine the reception outputs of each antenna element of the direction finding antenna. When using a method of substituting the pseudo omnidirectional output generated by the omnidirectional antenna as the output of the omnidirectional antenna, the problem arises that the received output to the direction finding side is reduced and the direction finding sensitivity is insufficient. Therefore, there is a problem in that it is expected that a method that solves the above problem by obtaining omnidirectional reception output for a low frequency band without relying on these methods will emerge.

。In this invention, a direction-finding antenna is placed above the midsection of one column, and a fan-shaped dipole antenna is placed on the middle section of the bottom column, thereby achieving omnidirectionality where the influence of the column is almost negligible. Even if you form an antenna with a polarity and occupy the top of the above-mentioned pillar as the location for placing the pond antenna, it is not possible to place the intended non-directional auxiliary antenna on one of the pillars and influence the pond antenna. This solves the above problem by making it possible to install them together without having to do so.

がある。According to this invention, as described above, the fan-shaped antenna is arranged in the midsection of the pillar below the position where the direction finding antenna is arranged to form an omnidirectional auxiliary antenna,
As shown, the antenna element 7A and the strut IA
The distance D1 between the parallel parts of the antenna element is set to be as close as possible within the range of 1/10 to 1/40 of the wavelength of the highest frequency in the frequency band that this antenna is responsible for. Since the upper end of 7A is placed at a distance that does not interfere with the lower end of the direction finding antenna element 6A above it, radio waves in the frequency band may cause interference errors or create dead frequency bands. In addition, as the antenna element 7A reaches the tip, it becomes larger than the diameter of the support column IA and protrudes on both sides of the support column IA, so that the direction of arrival of radio waves is on the side where the fan-shaped antenna is arranged. Almost the same reception sensitivity can be obtained for radio waves coming from the opposite side, that is, from the direction behind the pillar IA, so it can be operated as an omnidirectional antenna, and it can achieve the intended purpose. can be reached. Further, like the low frequency band direction finding antenna 6, the main body 6 is attached to the opening of the support arm 6B.
Place strut IB close to C, as shown,
The diameter D3 of the pillar IA is set to about 1/10 or less of the arrangement diameter of the antenna element 6A, that is, the span D2, and
The center of the main body 6C, that is, the center of the antenna 6 and the pillar I
Since the distance D4 to the center of A and IB is set to about 1/8 or less of the span D2, there is a useful effect that there is no adverse effect such as thickening the direction finding error. It has the advantage of being able to construct a pole-mounted radio direction finding antenna device at low cost and with small equipment.
