Abstract
A microfluidically reconfigurable slow wave phase shifter (MRPS) with integrated actuation is introduced. MRPS is based on a selectively metalized plate (SMP) repositionable within a microfluidic channel placed in close proximity to a microstrip line. SMP repositioning creates a variable capacitive loading to alter the speed of the propagating wave. The device exhibits < 2 dB insertion loss (IL) and a reconfiguration time of 50 ms. The $|S_{21}|$ , $|S_{11}|$ , and phase performances are characterized to be stable with respect to gravity by no more than 0.16 dB, 3.02 dB, and 7.73° variations, respectively. Vibration test shows 0.08 dB in IL, 1.72 dB in return loss (RL), and 4.23° in phase variations. The device is expected to handle 5.2 W of continuous RF power.
期刊介绍:
The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
