One such attempt is to use polarized antennas to increase the capacity of a wireless channel. Types of polarization antennas include vertical polarization antennas, horizontal polarization antennas, and circular polarization antennas. In addition to extending the vertical and horizontal polarized antennas more than two dimensions to increase the channel capacity, there is a method using a mixture of electric field dipole and magnetic loop antenna. Such methods have many problems in effectively increasing the capacity of a wireless channel due to an increase in noise due to interference between antennas.

These types of polarized antennas have a disadvantage in that performance is degraded due to cross-polarization resulting from interference between each antenna.

이런 문제를 해결하기 위해 혼 안테나(horn antenna)와 반사기(reflector)를 사용하여 지향성을 증가시키는 방안이 제안되었다. 그러나 제안된 방안은 수직 편파와 수평편파에 제한되어 있어 한계를 갖고 있는 문제점이 있었다.To solve this problem, a method of increasing the directivity by using a horn antenna and a reflector has been proposed. However, the proposed method is limited to vertical polarization and horizontal polarization.

도 2는 혼 어레이 안테나(horn array antenna)와 반사기(reflector)를 이용한 송신단의 다차원 편파 안테나를 도시한 도면이다.FIG. 2 is a diagram illustrating a multi-dimensional polarization antenna of a transmitter using a horn array antenna and a reflector.

송신단에서 서로 독립적인 채널을 형성하는 다차원 편파 채널은 다수의 혼 안테나로 구성된 혼 어레이 안테나(210)를 통해 빔(beam)(21)이 형성된다. 본 도면의 실시예에서는 9개의 혼 안테나로 9개의 채널을 형성하는 혼 어레이 안테나(210)가 도시되어 있다. 강한 지향성(directivity)에 의해 서로 간섭을 일으키지 않는 각 채널별 독립적인 빔(21)들은 혼 어레이 안테나(horn array antenna)(210)를 통해 방사되어 파라볼라 반사기(parabola reflector)(220)에서 지향성(directivity)을 유지하면서 반사되어 송신된다(22). 도면을 참조하면, 파라볼라 반사기(220)에서 반사된 각 채널별 신호 빔(beam)(22)은 서로 평행하게 지향성을 유지하며 수신단으로 송신된다. 이러한 지향성 성질을 이용하여, 파라볼라 반사기(220)는 이동전화 기지국 간의 무선통신에 이용된다. 예를 들어, 일정 거리 떨어져 있으나 중간에 장애물이 없는 두 기지국 간의 무선통신(LoS, line of sight)에 있어서, 파라볼라 반사기(220)의 이러한 지향성 성질은 매우 유용하게 이용된다. 즉, 파라볼라 반사기(220)는 지향성을 향상시키는 웨이브 가이드(wave guide)로 사용된다.In the multi-dimensional polarization channel forming channels independent from each other at the transmitting end, a beam 21 is formed through the horn array antenna 210 composed of a plurality of horn antennas. In the embodiment of this figure, a horn array antenna 210 is shown that forms nine channels with nine horn antennas. Independent beams 21 for each channel that do not interfere with each other by strong directivity are emitted through a horn array antenna 210 to directivity in the parabola reflector 220. Is reflected and transmitted (22). Referring to the figure, the signal beams 22 for each channel reflected by the parabola reflector 220 are transmitted to the receiving end while maintaining directivity in parallel with each other. Using this directivity, the parabola reflector 220 is used for wireless communication between mobile phone base stations. For example, in wireless communication (LoS, line of sight) between two base stations at a distance but without obstacles in between, this directional property of the parabolic reflector 220 is very useful. That is, the parabola reflector 220 is used as a wave guide to improve the directivity.

혼 어레이 안테나(210)에 입력되는 신호들은 전송 채널들의 독립성을 최대로 유지하기 위해 수직/수평(vertical/horizontal) 편파 및 다차원 편파의 속성을 갖도록 한다.
Signals input to the horn array antenna 210 have properties of vertical / horizontal polarization and multi-dimensional polarization to maintain maximum independence of transmission channels.

도 3은 혼 어레이 안테나(horn array antenna)와 반사기(reflector)를 이용한 수신단의 다차원 편파 안테나를 도시한 도면이다.FIG. 3 is a diagram illustrating a multi-dimensional polarization antenna of a receiver using a horn array antenna and a reflector.

도 2의 송신단과 대응하는 도 3의 수신단에서는, 송신단의 파라볼라 반사기(220)에서 반사되어 송신된 지향성을 가진 편파 신호(32)를 수신하여, 수신 파라볼라 반사기(parabola reflector)(320)에서 반사(31)하여 다수의 혼 안테나로 구성된 혼 어레이 안테나(310)에서 수신하도록 한다. 즉, 수신 파라볼라 반사기(parabola reflector)(320)는, 서로 평행하며 지향성을 유지한 신호 빔(32)을 수신하여 서로 간섭을 일으키지 않도록 지향성(directivity)을 유지하면서 상기 혼 어레이 안테나(310)의 각 혼 안테나로 각 채널별 신호빔(31)을 전달하게 된다. 이로부터, 지향성을 가지고 서로 간섭을 일으키지 않는 독립적인 편파 신호들이 상호간섭(mutual coupling) 없이 수신되고 복원될 수 있게 된다.
In the receiver of FIG. 3, which corresponds to the transmitter of FIG. 2, the polarization signal 32 having the directivity reflected and transmitted by the parabolic reflector 220 of the transmitter is received and reflected by the receiving parabola reflector 320. 31) to be received by the horn array antenna 310 composed of a plurality of horn antennas. That is, the receiving parabola reflector 320 receives the signal beams 32 that are parallel to each other and maintains directivity, and maintains the directivity so as not to cause interference with each other. The signal beam 31 for each channel is transmitted to the horn antenna. From this, independent polarized signals that are directional and do not interfere with each other can be received and recovered without mutual coupling.

도 4는 E-플레인 형 혼 안테나(410)와 H-플레인 형 혼 안테나(420)를 도시한 도면이다.4 illustrates an E-plane horn antenna 410 and an H-plane horn antenna 420.

혼 안테나는 E-플레인 형(E-plane type) 혼 안테나(410) 또는 H-플레인 형(H-plane type)혼 안테나(420)으로 구현될 수 있다. E-플레인 형 혼 안테나(410)는 자기파 H를 최대한 억제하여 전기파 E로만 구성된, 상하 진동파를 방사하게 되며, 반대로 H-플레인 형 혼 안테나(420)는 전기파 E를 최대한 억제하여 자기파 H로만 구성된, 수평 진동파를 방사하게 된다.The horn antenna may be implemented as an E-plane type horn antenna 410 or an H-plane type horn antenna 420. The E-plane horn antenna 410 suppresses the magnetic wave H as much as possible to radiate the up and down vibration wave consisting of the electric wave E only, and the H-plane horn antenna 420 suppresses the electromagnetic wave E as much as possible. It consists of only a horizontal vibration wave to be emitted.

이러한 설계를 확장시켜, E-플레인 형(E-plane type) 또는 H-플레인 형(H-plane type)의 다수의 혼 안테나를 이용하여 다차원(N차원) 편파 안테나를 혼 어레이 안테나로써 설계할 수 있는데, 이는 도 2 및 도 3을 참조하여 전술한 바와 같다.
