Reconfigurable RF impedance tuner for match control in broadband wireless devices
TL;DR: The design of a broadband RF impedance tuner that is part of a dynamically reconfigurable automatic match control (AMC) circuit that can be used for a wide variety of wireless devices and intelligent RF front ends is presented.
Journal ArticleDOI
Impact of Ground via Placement in Grounded Coplanar Waveguide Interconnects
Arghya Sain,Kathleen L. Melde +1 more
TL;DR: In this paper, the authors proposed two new structures using staggered ground via fences and with defected side ground planes for improving GCPW performances while meeting fabrication and routing requirements, which improved the interconnect bandwidth by 62.2% and 27.8% respectively.
Journal ArticleDOI
Frequency Agility of Broadband Antennas Integrated With a Reconfigurable RF Impedance Tuner
Zhen Zhou,Kathleen L. Melde +1 more
TL;DR: The results show that adding the reconfigurable tuner can facilitate excellent frequency agility of the return loss of the broadband antenna over several narrow frequency subbands.
Journal ArticleDOI
Development of a Broadband Coplanar Waveguide-to-Microstrip Transition With Vias
Zhen Zhou,Kathleen L. Melde +1 more
TL;DR: In this paper, the presence and placement of the vias affect the bandwidth and alters the impedance of the transition, and the measured results on a transition show that a wideband transition with return loss better than 10 dB and an insertion loss less than 1.64 GHz is obtained.
Journal ArticleDOI
A Comprehensive Technique to Determine the Broadband Physically Consistent Material Characteristics of Microstrip Lines
Zhen Zhou,Kathleen L. Melde +1 more
TL;DR: In this paper, the authors describe a method to extract the relative complex dielectric permittivity from propagation coefficient measurements on microstrip lines, which can be used to characterize low-loss materials whose polarization is dominantly dipolar within the microwave frequency range in high speed packaging applications.
