Abstract
Silicon technologies enable today the development of cost effective millimeter-wave applications (60 GHz wireless link for example). In order to achieve higher data rates (> 10 Gb/s), we can now consider the sub-THz frequencies in order to take advantage of wider frequency bands. In this context, the development of low cost and highly integrated Si-based sub-THz wireless chipset is a hot topic; industrial Si Photonic PIN Photo-Diode can be used as sub-THz source. But a key challenge is the design of antennas and packages able to support ultra-broad band sub-THz transmission in a cost effective manner. We propose here the design of a 200-280 GHz antenna integrated in an organic substrate packaging technology. Simulated performances exhibit a gain of >8 dBi over a 33% bandwidth. A 3D printed plastic lens is then added to the system in order to increase the achievable gain up to 20 dBi.
