NEG’s Lens Antenna Utilized in Self-driving Bus Convoy Demonstration Experiment, Revolutionizing Mobile Communication with Use of Specialized Glass
- Specialized Glass Contributes to Transportation Infrastructure Development -

A lens antenna made with specialized glass, developed by Nippon Electric Glass Co., Ltd. (hereinafter "NEG"), has been used in a self-driving bus convoy experiment conducted in Shiga Prefecture, Japan. In this experiment, the lens antenna played a pivotal role in improving stable information transmission between buses in convoy, successfully addressing the challenges associated with conventional antennas used in standard mobile communication. This technology enables high-speed and high-capacity information communication through millimeter-wave communication.

Addressing Social Challenges: Achieving Stable Communication with Lens Antennas Using Specialized Glass

Self-driving bus convoys, offering increased transportation capacity without the need for additional drivers, are being considered as a way to create region-specific transportation infrastructure and next-generation mobility services. The demonstration experiment aimed to achieve convoying and self-driving of multiple buses through information communication between the leading bus and its followers.

The use of lens antennas made with specialized glass has resolved issues such as communication interruptions during turns in self-driving bus convoying, offering more stable information transmission compared to conventional antennas. Furthermore, it has improved throughput and reduced latency compared to traditional antennas. The lens antenna using specialized glass was developed to meet requirements for self-driving bus convoying.

Requirements for Antennas
- Stable communication during turns
- Compact size for easy installation anywhere
- Resistance to deterioration caused by rain or snow

Advantages of NEG’s Lens Antenna Using Specialized Glass
1. Customizable beam shaping for user needs
In the demonstration experiment, a specialized glass material with suitable dielectric constant and low loss tangent is used for lens design. By reducing loss tangent, radio wave loss was minimized, and the lens shape could be adjusted to send radio waves in one direction or over a broader area.

2. Stable communication even during turn
The lens antenna allowed directing radio waves towards the necessary direction, preventing unnecessary radiation. It achieved communication in a millimeter-wave band with high gain (9dBi) over a wide area, without null points. This innovation prevented communication interruptions during turns and ensured stable communication during convoying.

3. Potential application with beamforming technology
- Expanding the field of view for external vehicle sensors to enhance collision avoidance systems
- Installing sensors inside vehicles to prevent child abandonment
- Placing sensors in homes to monitor the well-being of elderly individuals

The lens antenna utilized in the experiment was designed using materials developed by NEG specifically for this demonstration. These lens antennas are adaptable to various conditions and functions, promising versatile applications in various aspects of daily life. The company is committed to addressing societal issues that go beyond the realm of communication.

Nippon Electric Glass Develops New Products, Expanding 5G Wireless Communication Area

Nippon Electric Glass — Tue, 28 Jun 2022 15:00:00 +0900

OTSU, Japan, June 28, 2022 /Kyodo JBN/ --
Nippon Electric Glass Co., Ltd.
Nippon Electric Glass Co., Ltd., headquartered in Otsu, Shiga Prefecture, Japan, has developed a transparent antenna, which is made of a glass substrate, and a repeater (*1), which uses radio wave lenses and does not require power supply, for 5G millimeter-wave wireless communication technology. These products will be exhibited at the fifth 5G Technology Expo to be held at Tokyo Big Sight from June 29 to July 1, 2022.

5G uses radio waves of two frequency bands, Sub-6 (under 6 GHz) and millimeter wave (28 GHz). To achieve high-speed communication, it is necessary to use the millimeter-wave band, which can secure a wide bandwidth. However, millimeter waves are significantly attenuated in the atmosphere. Due to strong linearity of propagation, they do not diffract behind obstacles. To cover a wide area, a mechanism to resolve these issues is required.

The newly developed transparent antenna has a special antenna pattern on a glass substrate, whose dielectric constant (*2) (4.0) and loss tangent (*3) (0.002) are the smallest in the world (*4). This is a highly efficient transparent antenna. The size of glass substrates can be increased, making it possible to manufacture multiple products from a single substrate. This contributes to improving the antenna productivity and enables formation of antennas for multiple bands on a single substrate. By making the antenna transparent, the antenna functionality can be added without spoiling the design and landscape of an installation location. The antenna can be installed in various locations, such as windows, walls, displays, and vehicles.

The repeater, which is the other newly developed product, consists of two radio wave lenses and a waveguide. It receives and retransmits radio waves and changes the direction of radio waves without power supply even under circumstances where radio waves are blocked by walls and window glass. By changing the shape of the lens, radio waves can be transmitted in a certain direction or over a wide range. The lens is not subject to deterioration caused by ultraviolet rays because it is made of glass. It can be used stably over a long period in various places, both indoors and outdoors.

The Company will contribute to expanding and spreading the use of millimeter-wave radio waves by marketing the two newly developed products.

Notes:
(*1) Repeater: A relay to receive and retransmit radio waves.
(*2) Dielectric constant: An index of polarizability when a voltage is applied to a material. The lower the relative permittivity, the lower the signal attenuation.
(*3) Loss tangent: A measure of energy when a dielectric substance is polarized. The smaller the loss tangent, the lower the conversion of electromagnetic energy into heat, and as a result attenuation of signals is reduced.
(*4) Smallest in the world: Among multi-component glass substrates, in 28 GHz, based on a survey conducted by the Company in June 2022.
