Development of New Products Expanding 5G Wireless Communication Area
Transparent Antenna
Repeater using Radio Wave Lenses
Background
Point 01 To achieve high-speed communication
5G uses radio waves of two frequency bands, Sub6 (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.
Point 02 The challenges of the spread of high-speed communication
However, the 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.
Transparent Antenna
✓ Antenna with high transparency and excellent efficiency
✓ Unique special glass substrate
Relative permittivity 4.0
Loss tangent 0.002
✓ Various antenna pattern formations are available.
Features
Point Large glass substrate is available.
✓ 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.
Example
✓ By making the antenna transparent, the antenna functionality can be added without spoiling the design and landscape of the installation location.
✓ The antenna can be installed in various locations, such as windows, walls, displays, and vehicles.
Repeater using Radio Wave Lenses
What's Repeater?
✓ It consists of two radio wave lenses and a waveguide, and is a relay to receive and retransmit radio waves.
How does It work?
✓ It receives and retransmits radio waves and changes the direction of radio waves even under circumstances where radio waves are blocked by walls and window glass.
Features
Point 1 No power supply required
✓ It can receive and retransmit radio waves and change the direction of radio waves without power supply.
Point 2 How radio waves are transmitted
✓ By changing the shape of the lens, radio waves can be transmitted in a certain direction or over a wide range.
Point 3 Reliability under outdoors environment
✓ It has little deterioration of UV rays and is stable for a long period in various places indoors and outdoors.
