"With more than two years of continuous efforts, Luneburg Lens antenna has been recognized by more and more users, and has been officially landed in more than 10 provinces across the country." On June 4, the opening day of the 31st China International Information and Communication Exhibition, Zheng Hongzhen, director of the Technology Research Institute of Foshan EAHISON Communications Co., LTD., walked into the "Communications Industry News" all-media news center and accepted the "Communications Industry News" all-media reporter interview when he made the above statement.

        EAHISON is a new generation of metamaterial information technology company. It has made original achievements in the basic research direction of electromagnetic black holes, metamaterial stealth technology medium materials, and has taken the lead in the field of metamaterial technology in the world. Metamaterial communication antennas, radar antennas, wave-transmitting materials, space-borne radar, maritime beacons, space communications, inter-satellite communications and other products and solutions have been initially developed. Moreover, it reserves a lot of technology in high-gain antenna lenses, scalable and reconfigurable metamaterial lenses, and has realized the industrialization of metamaterial lens antennas, which are widely used in the Chinese operator market and are being promoted and sold to global operators.

        Luneburg Lens antenna is one of the main products independently developed by EAHISON with independent intellectual property rights. Zheng Hongzhen said that in the past two years, the promotion of Luneburg Lens technology has many highlights. For example, the official supply in more than a dozen provinces in the country; In addition, the EAHISON Luneburg Lens antenna has been tested in more than 300 trials across the country, and the results show that the application of the lens can help operators solve pain points such as network coverage blind spots.

        From the current market promotion point of view, the market has changed the view of Luneburg Lens technology. Zheng Hongzhen stressed that two years ago, EAHISON was mainly popular science when promoting Luneburg Lens technology, such as telling potential customers what is Luneburg Lens technology and what technical characteristics of Luneburg Lens technology. "Through the promotion of these two years, we have a certain understanding of the technology, there is no need to do science popularization, obviously Luneburg Lens technology has been recognized by everyone." Zheng Hongzhen proudly said.

        However, EAHISON's in-depth development of Luneburg Lens never stopped. Zheng Hongzhen said that EAHISON has brought a number of new products this year, and these new products have upgraded the original Luneburg Lens antenna from both technology and product.

        Among them, there are two main features of multi-frequency and multi-beam Luneburg Lens antenna. One is to support the 700MHz to 3.5GHz band, and the other is to achieve multi-beam progressive under the condition of ensuring multi-frequency. Not only that, the support for multi-beams is also very flexible, horizontal multi-beams, vertical multi-beams are supported, and the number of beams can be advanced from three waves to six waves, or even more. At present, the product has achieved small batch delivery in some European markets, and customer reviews are good.

        The shaped beambeam Luneburg Lens antenna mainly solves the signal coverage problem of ultra-dense scenes such as sports venues and schools. The antenna can achieve accurate coverage and partition cutting effect through beamforming, which not only reduces the number of antennas used, but also reduces the coverage area, so that the carrying capacity of RRU is improved, and effectively solves the problem of good wireless network signal but slow network speed in dense areas.

        Multi-frequency fusion Luneburg Lens antenna, mainly for sea coverage scenes. This type of antenna can achieve 700MHz, 2.6GHz and 4.9GHz of China Mobile and China Radio and Television, or 800MHz, 1.8GHz, 2.1GHz, 3.5GHz and other multi-band integration of China Telecom and China Union, which can not only solve the problem of long-distance coverage of the sea area, but also solve the problem of long-distance transmission.

        For the future direction of development, EAHISON also put forward a clear plan. Zheng Hongzhen said that in the future, EAHISON is still based on Luneburg Lens technology to do some industrial planning, mainly to enrich product categories and application scenarios, and now it is mainly for high-speed rail scenes, and then it will provide cell expansion, three-dimensional multi-beam and other solutions for sea coverage, sports venues, airspace coverage and star chain connection.

        It is worth noting that in EAHISON's technical planning route, millimeter wave and satellite communication are also the application research directions of Luneburg Lens antenna.

        Zheng Hongzhen said that in millimeter wave, Luneburg Lens can converge multiple beams through refraction, improve radio wave gain and penetration ability, and effectively improve the coverage ability of millimeter wave.

        In the field of satellite communication, the Luneburg Lens antenna supports the transmission of multiple beams into space by virtue of the performance characteristics of three-dimensional multi-beam, and realizes the simultaneous communication with multiple satellites. Zheng Hongzhen believes that this mode of communication is more in line with the future trend. Because in low-orbit satellite communication, the communication capacity of a single satellite is limited, multi-star communication will be the future development direction. The multi-beam technology of Luneburg Lens antenna just matches it, and compared with the phased array antenna, Luneburg Lens antenna has a higher cost advantage.
