| 摘要 |
The present invention relates to the technology used to design, integrate and package the radio frequency (RF) part of an antenna system, for use in communication, radar or sensor applications, consisting of components such as waveguide couplers, diplexers, filters, distribution networks, antennas, integrated circuit packages and the like. The invention makes use of pin grid arrays (PGA) and ball grid arrays (BGA) to realize the RF part, based on the principle of gap waveguides. Gap waveguides are formed in the gaps between conducting surfaces. Thereby flat multilayer RF parts can be realized, as well as completely integrated RF front-ends including the packaged MMICs and frequency converters. The PGA and BGA technologies have never before been applied to RF applications. |
