    Abstract: The present invention provides a miniature wideband antenna for 5G, which includes a dielectric substrate, a coplanar waveguide feed structure on a front of the dielectric substrate, a main radiator, a second and third radiators and a first radiator on a back of the dielectric substrate. The antenna is small in size with operation band of 3 GHz-30 GHz which covers the various 5G frequency band and covers the current wireless modes of Wi-MAX, W-LAN, UWB and so on. The antenna guarantees future compatibility for various complicated communication modes and has good perspectives for many applications. Based on the antenna, the double-unit and four-unit MIMO antenna adopts orthogonal polarization and metamaterial unit. Thus, high unit separation is achieved without increase on the size of the antenna unit. The present invention has wide applications in small mobile device such as cell phone and laptop.

    Abstract: A metamaterial high-power microwave source relates to the fields of vacuum electronic technology, particle physics, and accelerators, including: a cathode, a metamaterial slow-wave structure (SWS), a waveguide and coaxial line coupler located at one end of the metamaterial SWS and a collector component located at the other end of the metamaterial SWS. The metamaterial SWS provided by the present invention is greatly smaller than a rectangular waveguide having the same frequency, so as to realize a miniaturization of devices and facilitate integration with semiconductor devices. The waveguide and coaxial line coupler has a good transmission characteristic and a low reflection in a relatively wide frequency band, which guarantees a high-efficient coupling output of a signal. Moreover, the metamaterial high-power microwave source has a high-power output and a pulsed output power reaching a megawatt level.
