“…In these contexts, a six-port receiver is a good alternative, as well as for low volume markets. Six-port technology has been under development over past 30 years, and this concept is a serious alternative for microwave and millimeter-wave frequencies and ultrahigh-bandwidth applications in wireless sensing, radar, medical and communication systems [4][5][6][7][8]. Good matching at all ports, good isolation between ports, good phase and amplitude balance, within the desired frequency band are the main goals in design procedure.…”

Abstract-Every generation of mobile communication has been associated with higher data rates than the previous generation. So 5G new spectrum radio access should support data rates exceeding 10 Gbps in most of its applications. An Ultra Wide Band (UWB) ultrahigh data rate full six-port receiver architecture up to 6.7 Gbps for 5G new spectrum is presented in this paper. The proposed structure is constructed using one UWB ultra-high data rate Wilkinson power divider/combiner and three UWB ultra-high data rate two-stage branch line couplers which are the essential components of any full sixport structure. The design procedure, optimization and implementation of these two UWB essential components in 21-30 GHz are completely done to achieve the optimum performance of final six-port structure. The final fabrication results show the average of −14 dB of input matching, −20 dB of isolation of isolated Ports, −4.2 dB of coupling in output ports (considering 2 SMA connectors and transitions in each path), and linear phase variation of outputs in the whole bandwidth of 21-30 GHz. To analyze and qualify the UWB six-port structure in any specific application in 5G and other UWB high data rate applications, a new analytical formulation with a new six-port structure of non-ideal UWB six-port circuit is presented. With this new analytical model and new configuration, there is no need to calibrate the outputs of in-phase and quad phase of the six-port receiver outputs. Based on the final fabricated essential components and the new analytical model, the final full six-port structure is constructed and analysed using UWB-OFDM with QPSK and 16QAM demodulation schemes in its sub-bands. To complete and verify the new analysis and to validate the final constructed UWB six-port structure and its essential components in ultra-high data rate application in 5G new spectrum, the UWB-IR impulse radio with modulated ultra-high data rate signal up to 7 Gbps and in 21-30 GHz bandwidth is completely discussed. The results show that all clusters of demodulated constellations are very well positioned and individualized in whole bandwidth in all modulation schemes. Also this new design and configuration of six-port receiver improves the dynamic range of the RF input signals up to 60 dB which is valuable. During the design procedure, a very useful method to choose the suitable laminate based on the time, frequency and two dimensional Wigner-Vile Distribution methods is presented. Also, some practical issues in design and implementation of the UWB microstrip component such as transitions are considered to achieve the best results.

Abstract-In this paper, a calibration technique for the position sensor via support vector regression (SVR) is proposed. The position sensor adopts a zero-intermediate frequency architecture based on a six-port network, which is used for directly measuring the phase differences and indirectly reflecting the position. The SVR, which implements the structural risk minimization (SRM) principle, provides a good generalization ability from size-limited data sets. The results indicate that the SVR model can achieve a great predictive ability in positioning, with an accuracy of 2.41 mm over a distance range of 274.5 mm.
