In particular, the high-gain reflector antennas will be examined in this work, where the antennas will be designed by considering all-metal materials to assure the capability of handling high-power radiation, and also assure the radiation efficiency at (mmW). The proposed antenna technologies are applicable to a variety of industries including the military defense, space communications, mobile communications and Internet of things (IoT), which requires high-data rate transmission by using the broadband spectrum at mmW. The collaborating industry—Universal Microwave Technology (UMT) is a worldwide well-known company majoring in the microwave components at mmW, which has established a complete capability in the design and manufacture of microwave components. The development of antenna technologies will allow the company to provide a complete microwave system at higher product values. As a result, the developed technologies will become one of the core technologies in this microwave link industry. In order to enable the industrial applications to meet the need of time-to-market, numerical simulation software will be also developed, which will integrate the existing software modules of numerical techniques that have been developed by our research team in the past years. These tools in combination with the hardware development, will form the core technologies for the microwave links. 表應用於微波鏈結之毫米波高增益天線技術發展(1/2)
