Vertical Transition in Multilayer Millimeter Wave Module Using Circular Cavity

A novel transition structure based on Substrate Integrated Circular Cavity (SICC) is proposed in this paper. The design approach of the transition structure can also be used in other operating frequency. Good performance of flexibility and S-parameters were observed for the new transition structure. Different design tools were used to validate the design method.

Novel On-Chip Antenna Structures and Frequenqy Selective Surface (FSS) Approaches for Millimeter Wave Devices

This paper presents novel on-chip antenna structures and provides new on-chip circuit concepts that may be implemented as part of standard integrated circuit fabrication processes for wireless integrated circuits of the future. As wavelengths of wireless local area networks (V\'LANs) and personal area networks (PANs) shrink to millimeter lengths at 60 GHz and above, interconnectivity issues and...

A Fully Integrated CMOS Pulse Transmitter with On-Chip Antenna Array for Millimeter-Wave Imaging

This dissertation focuses on the implementation of integrating pulse transmitter with wide-band antenna array into a chip by CMOS process for beam-forming in millimeter-wave (mm-wave) active imaging applications. Integrated antenna arrays in this research electrically control and steer radiated-pulse beams towards objects to be imaged. Among imaging approaches, active imaging method provides mo...

Low-loss Millimeter-wave Phase Shifters Based on Mechanical Reconfiguration

We propose different concepts of mechanically reconfigurable true-time-delay phase shifters using micro-actuators at millimeter-waves (MMW). The mechanical reconfiguration allows to achieve phase shift reconfiguration with very low losses. One of the proposed concepts has been fully implemented and tested, demonstrating state-of-the-art performance in terms of phase-shift/loss ratio.
