  RF specialist company HJ Wave Co., Ltd. (CEO Yoo Tae-Hwan) announced on the 4th that it has supplied four types of communication antennas to the smart factory of the world’s top white goods company. The supplied antennas include one type for AGVs (Automatic Guided Vehicles), which are unmanned transport vehicles, and three types for RSUs (Road Side Units) used for communication. The RSU antennas consist of a V2X antenna, an LTE/5G antenna, and a GPS L1&L2 antenna. These products support communication and autonomous logistics and driving between vehicles and road devices through the GNSS system for receiving location information. They also support connectivity to LTE/5G mobile communication networks. The V2X/GPS L1&L2 antenna supports frequencies of 1.2GHz, 1.5GHz, and 5.9GHz, with gains of 9-10dBi and 25-30dBic. The LTE/5G antenna operates in three frequency bands: 824-960MHz, 1710-2690MHz, and 3300-3900MHz, with an antenna gain of 2.5-5dBi. In addition, a communication a...
