Description

RDSS、VSAT复合抛物面天线装置RDSS, VSAT compound parabolic antenna device

技术领域technical field

本公开属于卫星通信技术领域,本公开尤其涉及一种RDSS、VSAT复合抛物面天线装置。The present disclosure belongs to the technical field of satellite communication, and in particular, the present disclosure relates to an RDSS and VSAT compound parabolic antenna device.

背景技术Background technique

VSAT(Very Small Aperture Terminal)天线和RDSS(Radio DeterminationSatel-lite System)天线都为船载通信系统的重要组成部分,两者各成系统,各有应用。The VSAT (Very Small Aperture Terminal) antenna and the RDSS (Radio DeterminationSatel-lite System) antenna are both important components of the shipborne communication system, and they each form a system and have their own applications.

VSAT天线负责跟踪地球同步通信卫星,通过卫星与地面公共网连接,负责高速信号传输,用于渔船视频监控、信息娱乐等。The VSAT antenna is responsible for tracking geostationary communication satellites, connecting with the ground public network through satellites, and responsible for high-speed signal transmission for video surveillance of fishing boats, infotainment, etc.

RDSS负责跟踪RDSS地球同步卫星,以短报文形式直接与指挥中心或特定用户通信,负责低速信息传输,在渔业船位监控和救援系统中得到广泛应用。RDSS is responsible for tracking RDSS geostationary satellites, communicating directly with the command center or specific users in the form of short messages, and is responsible for low-speed information transmission, which is widely used in fishing vessel position monitoring and rescue systems.

天线形式上,VSAT天线一般都为0.6~2.4米抛物面所组成(C、Ku或Ka频段),其频率较高,波束较窄(1~3°),因此一般会增加天线伺服稳定底座,用于将波束固定跟踪同步卫星。In terms of antenna form, VSAT antennas are generally composed of 0.6-2.4-meter paraboloids (C, Ku or Ka frequency bands), and their frequencies are higher and the beams are narrower (1-3°). It is used to fix the beam to track the geostationary satellite.

而传统的RDSS天线一般为微带型和振子型天线。微带型天线的圆极化合成一般由两个线极化功分器加90度移相器的微带电路组成,具有体积小,重量轻,集成度较高,成本低的特点。而振子型天线主要利用单元振子作为馈源的辐射单元,避免了微带天线介质带来的损耗,因此馈源效率较高。The traditional RDSS antennas are generally microstrip and dipole antennas. The circular polarization synthesis of the microstrip antenna is generally composed of two linearly polarized power dividers and a microstrip circuit with a 90-degree phase shifter. It has the characteristics of small size, light weight, high integration and low cost. The oscillator type antenna mainly uses the unit oscillator as the radiating element of the feed source, which avoids the loss caused by the medium of the microstrip antenna, so the feed efficiency is higher.

上述两种天线,由于体积受限(一般为

Figure BDA0002616003630000011
左右),其增益不高(-3~5dBi),旁瓣和后瓣较大,易受到其它船载设备的干扰,导致其一般只能近海使用,应用受限。The above two antennas, due to the limited size (usually
Figure BDA0002616003630000011
around), its gain is not high (-3 ~ 5dBi), the side lobes and back lobes are large, and it is easy to be interfered by other shipborne equipment, so that it can only be used offshore and its application is limited.

随着远洋渔业和运输发展,此外,北斗RDSS天线的应用范围,已经逐步由近海向中远海方向扩展。如前所述,受到低增益天线的限制,传统的北斗RDSS服务区仅限于中国周边的亚太地区,东经80-140度,北纬5-55度区域,已经不能满足需求。如果需要扩展到欧洲、大洋洲等其它周边海域,则需要进一步提高天线增益,加大天线面积和使用天线伺服系统,如果单独实施,将大幅增加RDSS天线的复杂度和成本。另一方面,传统的RDSS和VSAT各成系统,需要安装两副天线才能使用,增加了对使用场地、人员的要求,存在着成本高,占地面积大等缺点,不符合多系统高集成度的船载通信技术趋势发展需求。With the development of distant-water fisheries and transportation, in addition, the application scope of Beidou RDSS antennas has gradually expanded from the offshore to the middle and far seas. As mentioned above, due to the limitation of low-gain antennas, the traditional Beidou RDSS service area is limited to the Asia-Pacific region around China, 80-140 degrees east longitude and 5-55 degrees north latitude, which can no longer meet the demand. If it needs to expand to other surrounding sea areas such as Europe and Oceania, it is necessary to further increase the antenna gain, increase the antenna area and use the antenna servo system. If it is implemented separately, it will greatly increase the complexity and cost of the RDSS antenna. On the other hand, the traditional RDSS and VSAT are separate systems, and two antennas need to be installed before they can be used, which increases the requirements for the use site and personnel. The development needs of shipborne communication technology trends.

随着微波技术的发展,特别是多频复合抛物面馈源设计技术的成熟,使得同时覆盖RDSS(L、S频段)的VSAT(C、Ku、Ka)频段的宽带多频抛物面天线成为可能。With the development of microwave technology, especially the maturity of multi-frequency compound parabolic feed design technology, broadband multi-frequency parabolic antennas covering VSAT (C, Ku, Ka) frequency bands of RDSS (L and S frequency bands) at the same time become possible.
