Abstract

To exploit the extremely wide bandwidth in the THz region for ultra-high-speed wireless communication, UTCPD- based THz emitters enjoy a wide bandwidth and high linearity, but face challenges in increasing power due to saturation effects and thermal effects. We designed a 16-way WR3 power combiner for 12 dB gain using the Y-branch structure in the 300 GHz band. Additionally, a 37.7 dBi gain reflector-integrated diagonal horn antenna was developed for a pencil beam at 300 GHz. Furthermore, ongoing efforts are dedicated to manufacturing them with 3D printing technique.
