12 : 제2안테나 13 : +피더선12: 2nd antenna 13: + feeder ship

20 : 스위칭 수단20: switching means

본 고안은 편파(Polarized Wave) 선택형 안테나에 관한 것으로, 특히 제1 및 제2안테나와 스위칭 수단이 세트로 이루어져 좌원편파, 우원편파 및 직선편파를 스위칭수단에 의해 선택하여 송수신 할수 있도록 한 것이다.The present invention relates to a polarized wave (Polarized Wave) selective antenna, in particular the first and second antennas and the switching means is a set so that the left circular polarization, right circular polarization and linear polarization can be selected and transmitted and received by the switching means.

일반적으로 차량용 무선 수신시스템 등에서는 헤리칼 안테나를 사용하여 송수신하고 있는바, 도체를 난선형으로 감은 구조를 이룬다. 이는 도체를 나선형으로 감으면 둘레의 길이가 파장의 3/4∼4/3배로 되어(나선의 피치가 λ/10∼λ/2 일때)도선을 따라서 진행파가 실리고 방사의 메인빔이 축방향을 향하게되어 거의 원편파에 가까운 전파가 방사된다.In general, a wireless reception system for a vehicle is used to transmit and receive using a helical antenna, and thus the conductor is wound in an ovoid shape. When the conductor is wound in a spiral, the length of the circumference becomes 3/4 to 4/3 times the wavelength (when the pitch of the spiral is λ / 10 to λ / 2), and a traveling wave is carried along the wire and the main beam of radiation is axially oriented. And radio waves are emitted that are nearly circularly polarized.

이 안테나는 100∼1,000MHz 정도의 광대역 특성이 있음으로 TV방송, 초단파(VHF) 차량용 무선통신 등에 사용된다.This antenna has a broadband characteristic of about 100 ~ 1,000MHz and is used for TV broadcasting, VHF vehicle wireless communication and so on.

그런데 전자기파의 송수신 시스템에서는 송수신의 편파형태와 수신기가 잘 매칭되어야 필요한 능률을 획득할 수 있으며, 직선편파의 수신을 위해서는 직선편파의 수신기(일반적 이동통신 시스템 편파의 경우)가 필요하고, 원형편파의 수신을 위해서는 원형편파의 수신기(위송방송의 경우)가 필요하다.However, in the transmission / reception system of electromagnetic waves, the required polarization type and receiver must be well matched to obtain the required efficiency.In order to receive the linear polarization, a linear polarization receiver (in the case of a general mobile communication system polarization) is required. For reception, a circularly polarized receiver (in case of a broadcast broadcast) is required.

예를들면 제1a도는 좌원편파용 해리칼안테나를 도시하고, 제1b도는 좌원편파의 일예를 도시한 것으로, 기판(1)에 좌원편파용 혜리칼 안테나(2)가 설치된 것이다.For example, FIG. 1A shows a helical antenna for left circular polarization, and FIG. 1B shows an example of a left circular polarization, in which a left circular polarization hyelic antenna 2 is provided on a substrate 1.

제2a도는 우원편파용 헤리칼 안테나를 도시하고, 제2b도는 우원편파의 일예를 도시한 것으로, 기판(1)에 우원편파용 헤리칼 안테나(3)가 설치된 것이다.FIG. 2A shows a right circularly polarized helical antenna, and FIG. 2B shows an example of a right circularly polarized wave, and the right circularly polarized helical antenna 3 is provided on the substrate 1.

제3a도는 직선편파용 헤리칼 안테나를 도시하고, 제3b도는 직선편파의 일예를 도시한 것으로, 기판(1)위에 우원편파용 헤리칼 안테나(3)와 좌원편파용 헤리칼 안테나(2)가 차례로 연결되어 직선편파용 헤리칼 안테나(4)를 구성하도록 이루어진 구조이다.FIG. 3A shows a linearly polarized helical antenna, and FIG. 3B shows an example of linearly polarized light. A right circularly polarized helical antenna 3 and a left circularly polarized helical antenna 2 are placed on a substrate 1. It is connected to one another in order to form a linear polarized helical antenna (4).

이는 수신기의 종류에 따라 좌원편파 헤리칼 안테나 우원편파 헤리칼 안테나 및 직선편파용 헤리칼 안테나를 지역에 따라 또는 용도에 따라 각각 별도로 설치사용하여야 하는 불편함에 있다.This is inconvenient to install the left circularly polarized helical antenna and the right circularly polarized helical antenna and the linearly polarized helical antenna according to the type of region or the purpose according to the type of receiver.

본 고안은 이를 해결코자 하는 것으로, 하나의 안테나로써 좌, 우원편파 및 직선편파 형태로 송수신이 가능한 안테나를 제공함을 특징으로 한다.The present invention is to solve this problem, it is characterized by providing an antenna capable of transmitting and receiving in the form of one, left and right polarization and linear polarization as one antenna.

즉, 기판위에 설치되는 헤리칼 안테나에 있어서, 기판위에 우원편파용 제1안테나와, 좌원편파용 제2안테나가 차례로 위치되며, 스위칭수단에 의해 제1, 제2안테나 및 + 피더선이 선택 연결되어 좌원편파, 우원편파 및 직선편파용 안테나로 선택작동되도록 이루어진 것이다.That is, in the helical antenna installed on the substrate, the first antenna for the right circular polarization and the second antenna for the left circular polarization are sequentially positioned on the substrate, and the first, second antenna and the + feeder line are selectively connected by switching means. The left circular polarization, right circular polarization and linearly polarized antennas are made to operate selectively.

이하 도면을 참조하여 상세히 설명하면 다음과 같다.When described in detail with reference to the drawings as follows.

제4도는 본 고안의 구조도, 제5도는 본 고안에 의해 직선편파용 안테나로 사용되는 경우의 구조도로, 기판(1)위에 우원편파용 제1안테나(11)와 좌원편파용 제2안테나(12)가 차례로 위치되며 제1 및 제2안테나(11,12)와 제1안테나(11) 및 + 피더선(13)은 스위칭수단(20)에 의해 선택연결되도록 이루어진다. 상기 스위칭수단(20)은 제1안테나(11)의 상부접점(b)과 제2안테나(12)의 하부접점(a)과, 제1안테나(11)의 하부접점(c)과 기판(1)과 절연되어 위치되는 + 피더선(13)의 접점(d)을 각각 선택하도록 연결되는바, 이는 릴레이등에 의해 구현가능함은 알 수 있을 것이다.FIG. 4 is a structural diagram of the present invention, and FIG. 5 is a structural diagram when it is used as a linearly polarized antenna according to the present invention. The first antenna 11 for right-circular polarization and the second antenna for left-circular polarization on the substrate 1 are shown in FIG. 12 are sequentially positioned, and the first and second antennas 11 and 12 and the first antenna 11 and the + feeder line 13 are configured to be selectively connected by the switching means 20. The switching means 20 includes an upper contact b of the first antenna 11 and a lower contact a of the second antenna 12, a lower contact c of the first antenna 11, and a substrate 1. It is connected to select the contact (d) of the + feeder line 13 is insulated from the (), it will be appreciated that this can be implemented by a relay or the like.

이와 같이 구성된 본 고안을 사용할 때 제1도와 같이 좌원편파용 헤리칼 안테나로 사용함에 있어서는, 제2안테나(12)의 접점(a)을 + 피더선(13)의 접점(d)에 연결되도록 스위칭수단(20)을 조작하여 사용하면 된다. 물론 이때 제1안테나(11)는 제2안테나(12) 및 접점(d)과 차단된다.When using the present invention configured as described above, in using as a left circular polarized helical antenna as shown in FIG. 1, the switching means is connected to the contact a of the second antenna 12 to the contact d of the + feeder line 13. What is necessary is just to operate (20). Of course, at this time, the first antenna 11 is cut off from the second antenna 12 and the contact d.

이어 우원편파용 헤리칼 안테나로 사용할 때에는, 스위칭수단(20)에 의해 제2안테나(12)의 접점(a)를 차단하고 제1안테나(11)의 접점(c)을 접점(d)과 연결시키면 우원편파용 헤리칼 안테나인 제1안테나(11)만 구동된다.Subsequently, when used as a helical antenna for right circular polarization, the contact means (a) of the second antenna 12 is cut off by the switching means 20 and the contact point c of the first antenna 11 is connected to the contact point d. In this case, only the first antenna 11 which is a helical antenna for right circular polarization is driven.

또한 직선편파용 헤리칼 안테나로 사용할때에는 제1안테나(11)의 접점(b)과 제2안테나(12)의 접점(a)을 도통시키고, 제1안테나(11)의 접점(c)과 접점(d)을 도통시켜 제5도와 같이 연결되게 하고, + 피더선(13)에 + 극성을, 기판(1)에 - 극성을 인가하면 된다.In addition, when used as a linearly polarized helical antenna, the contact b of the first antenna 11 and the contact a of the second antenna 12 are conducted, and the contact c and the contact of the first antenna 11 are conducted. (d) is conducted so as to be connected as shown in FIG. 5, + polarity is applied to the + feeder line 13, and-polarity is applied to the substrate 1.

이상과 같이 본 고안은 기판위에 제1 및 제2안테나를 직렬로 위치시키고 각 안테나는 스위칭 수단으로 스위칭시켜 필요한 편파를 송수신 함으로써, 각 편파에 따른 안테나를 별도로 설치할 필요가 없다.As described above, the present invention places the first and second antennas on a substrate in series, and switches each antenna by a switching means to transmit and receive necessary polarizations, thereby eliminating the need to separately install an antenna according to each polarization.
