Wideband via-Loaded Cylindrical Open-Ended SIW Cavity Antenna
IEEE Open Journal of Antennas and Propagation, 2021 A composite cavity-based antenna is proposed and presented in this work. Three kinds of modes of the composite structure are involved to obtain a wide bandwidth: the ${\mathrm {TE}}_{11 {\scriptstyle {}^{\scriptstyle 1}}\hspace {-0.224em}/\hspace {-0 ...

Experimental Study of Adaptive Control of High-Speed Flow-Induced Cavity Oscillations
Journal of Fluid Science and Technology, 2011 This paper describes progress towards the development of an active suppression system for open cavity oscillations. A leading-edge array of piezoelectric zero-net mass-flux (ZNMF) actuators is used to suppress cavity flow oscillations determined from ...

Sub-6GHz 4G/5G Conformal Glasses Antennas
IEEE Access, 2019 The difficulty of antenna design applied to glasses is that the structure of glasses is too single, and the space available for antenna design is greatly limited. In this background, the integrated design of 4G antennas and 5G antennas applied to glasses
