CRHM 

The development of low-dielectric constant and low-loss substrate materials is making some progress. The inkjet printing process was carried out. In this process, the dielectric layer has a dielectric constant of 3.5 and dielectric loss of 0.003 at 10GHz by adjusting the contents of ceramic, resin, and air using DoD (Drop on Demand) technology that drops the exact amount of ink in the correct position. The results were obtained. In addition, as a result of measuring insertion loss and return loss by forming electrodes by inkjet on the obtained hybrid film, characteristics of S21: 2db and S11: 20db were shown at 40GHz. It is a level where there is no problem with making any part up to 40 GHz. Therefore, an antenna and a bandpass filter that can be used for Ku-band satellite communication were manufactured, and excellent characteristics were obtained. We have a single inkjet process, and since PTFE and LCP of world major Rogers and Murata are manufactured with CCL, their process is complicated and expensive, and the initial investment is a photolithography process, so we have great competitiveness in terms of production cost. Currently, we are responding to environmental tests, but there are no major problems. We are finally trying to manufacture antenna modules for Ku or Ka band 5G, satellite communication and self-driving cars, and we are currently exchanging with several domestic and foreign companies. There is no doubt that the frequency band of communication in the world will gradually increase in the future, so substrate materials and processes suitable for this must be established in Korea, otherwise the United States or Japan will continue to depend on core materials. We ask for your support so that this technology, which has been researched and developed as a national development project since 2007, can blossom.
