HJWAVE (CEO Yoo Tae-hwan), a millimeter wave (mmWave, 30–300 GHz) RF specialized company, announced on the 8th that it has launched a 24 GHz antenna that implements and internalizes waveguide technology by utilizing copper and vias of PCBs instead of waveguide antennas that were previously manufactured only by plating metal or injection molded products.

HJWAVE said, “ITS (Intelligent Transport Systems) based on smart cities require cooperative driving between vehicles and traffic control systems. In order to perfectly implement this, high detection distance and wide detection range functions of traffic control radar are required. Accordingly, we have developed a PCB antenna product that applies waveguide technology in the 24 GHz frequency band that can improve detection distance, increase detection area, reduce size, and reduce price.”

CEO Yoo Tae-hwan said, “By implementing the waveguide technology with high antenna gain characteristics into the internal layer of the PCB, which was difficult to apply due to manufacturing techniques, we have expanded the component mounting area, contributing to the miniaturization of the finished product and cost reduction. We plan to develop various frequencies as PCB waveguide antenna types in the future.” 

He continued, “We have completed the patent application for the technology, and we expect that it can be used in the Ku-band (12–18 GHz) and Ka-band (26.5–40 GHz) frequency bands of 5G, 6G mobile communications and low-orbit satellite communications in the future. We also announced that we plan to release a product that applies the waveguide technology to an injection-molded object such as a radome in the near future.
