The 5G 28 GHz band compatible On-Glass Antennas used in the field trial were designed and developed by AGC. The antennas are not easily seen from the exterior and can be installed on glass surfaces without affecting the vehicle design.
For this field trial, 5G high-speed communications using both the beam forming function and the MIMO function was performed with a vehicle equipped with On-Glass Antennas. The trial was held at the National Institute for Land and Infrastructure Management in Ibaraki Prefecture, Japan. While moving at high speeds of approximately 100 km/h, a maximum communication speed of 8 Gbps was achieved, and a maximum of 11 Gbps was achieved at a speed of approximately 30 km/h, confirming that high-speed in-vehicle communications in the 28 GHz band can be achieved by utilizing On-Glass Antennas.

Details of 5G Field Trial Using “Vehicle Glass Mounted Antenna”
1. Field trial outline and results
The trial was carried out at a straight section of test course approximately 2.2 km long at the National Institute for Land and Infrastructure Management. 5G data communications were carried out using the 28 GHz band between the moving test vehicle equipped with a 5G mobile station to which several On-Glass Antennas were connected and three 5G base stations set up along the sides of the course.
By utilizing the On-Glass Antennas to receive signals in combination with the MIMO function and the beam forming function with up to four beams supporting vertical and horizontal polarization, 5G high-speed communications were realized, with up to 8 Gbps at a moving speed of approximately 100 km/h, and 11 Gbps at a moving speed of approximately 30 km/h.
