This paper proposes a varactor-based coupler structure that allows for reconfigurable
operating frequency, power-dividing ratio, and coupler to/from crossover responses …

A highly reconfigurable and switchable quadrature coupler with simultaneous control in
terms of operating frequency, coupling ratio, and coupling direction is presented. To start …

This paper presents a millimeter-wave (mm-wave) on-chip coupler with tunable power
dividing ratios and constant phase response. Composed by two coupled lines, two …

This paper presents a compact planar tunable quadrature coupler with improved phase
responses. Wide coupling-tuning ratio is achieved by using two varactors loaded on the …

A novel circular reconfigurable metasurface (MS) based compact ultra-wideband (UWB)
hybrid coupler is developed for Ku-band applications. The coupler is developed using the …

A highly reconfigurable and switchable patch coupler is presented with controllability of the
operating frequency, power-dividing ratio, and switching coupling direction for millimeter …

Current waveguide flange standards do not allow for the accurate fitting of microchips, due
to the large mechanical tolerances of the flange alignment pins and the brittle nature of …

Commencing with a review of the characteristics of RF-MEMS in relation to 5G, the book
proceeds to develop practical insight concerning the design and development of RF-MEMS …

This thesis presents the analysis and design of a microwave radiometer for internal body
temperature measurements. There is currently no available method for non-invasive …

We report rigorous approach for the design of differential coupled-line directional couplers in
multilayer dielectric structures. In the proposed procedure numerically calculated per-unit …
