Dai Nippon Printing Co., Ltd. (DNP) announced on April 14 that it has developed a film-type antenna with high design and weather resistance that supports the 5G Sub6 frequency band and can be wound around a thin cylinder with a diameter of 15 cm.

Since the radio waves of the Sub6 band frequency used in 5G capable of high-speed and large-capacity communication have a short communication distance, it is necessary to install a large number of base stations and antennas that cover the area where people can communicate, but conventional antennas are street lights and In addition to being difficult to wrap around a column such as a utility pole and installing it, there were problems such as not being in harmony with the landscape in terms of design.

In response to these issues, the company devised a shape and feeder design to support the bandwidth of 100 MHz or more allocated to each communication carrier in the 5G-Sub6 band, and even a thin cylinder with a diameter of 15 cm. Developed a flexible film-type antenna that can be wound.

By utilizing DNP's original EB coating technology that cures the functional resin coated on the film by irradiating it with an electron beam, the weather resistance is improved and the landscape is designed in consideration of the environment of the installation location. It is said that the product can be installed outdoors without damage.
