This paper presents a heterogeneous integrated micro-electro-mechanical system (MEMS) switching filter bank with silicon as the substrate. The silicon-based MEMS filter has the advantages of high Q value and low fabrication cost. The design solves the problem of large size and low integration of conventional filters. The filter bank is heterogeneously integrated between silicon by means of four filters layered two by two on the top and the bottom. A through silicon via (TSV) method is used to conduct the RF signal from the upper or lower layer to the output of the middle layer. The size of this assembly is significantly reduced without compromising the out-of-band rejection. In addition, this module improves the inter-channel isolation of the filter bank to a certain extent due to the low reflection effect of the coupling between the silicon on the RF signal.

A two-port circular patch antenna with a novel de-coupling structure for multiple-input-multiple-output (MIMO) application is proposed. The slim metal plates and the metallic screws are utilized to construct a pair of series resonators, which provide a high port isolation for the antenna. Owing to this proposed decoupling structure, only one radiating patch is needed and a compact dimension of $pitimes(0.25lambda_{0})^{2}times 0.06)lambda_{0}$ is achieved. The measured -10 dB impedance bandwidth is 3.21-3.52 GHz (9.2%). A measured port isolation better than 18.6 dB is realized in the operating band and the peak value achieves 44.1 dB. Measured efficiency is higher than 83 % and peak gain is about 6.5 dBi. Finally, a three-port antenna based on the same principle is proposed. Overall, the proposed two antennas with a compact structure, high port isolation and good radiation performance are suitable for MIMO application.

This paper presents a 58-65GHz 6-bit active vector synthesis phase shifter (PS) in a 40nm CMOS. To generate I/Q signals, a compact differential capacitor-free quadrature generator circuit (QGC) based on folded transformer is proposed. Two additional transformer-based series peaking are placed between the second-stage amplifier and the digital-to-analog converter (DAC) to obtain wider bandwidth. The post-layout simulation results show that the proposed 6-bit PS achieves a 3-dB band-width of 58 ~ 65GHz. The simulated root-mean-square (RMS) phase error is 0.7° ~ 2.1° and the RMS gain error is 0.35 ~ 0.5dB within the 3-dB bandwidth. The core area of the PS is only $240text{um}times 570text{um}$.

To calculate the required RF power for the transmitters for a mobile satellite link, radar equations are utilized. In this work, the requirements of K/Ka receiver/transmitter antenna arrays for modern communication system which consists of two separate antennas are achieved to create scanning radiation patterns for transmitter and receiver for a 5G/6G system for VSAT applications. Having analyzed the link budget, it is shown that the antenna systems have to include 64×64 arrays which prepare at least 35dB array gain and the total transmitted RF power must be more than about 603W (60.3W in clear sky). For a typical TX/RX 5G/6G system, specifications can be: TX frequency: 19GHz up to 21GHz; RX frequency: 27GHz up to 31GHz; SWR: <3; three dimensional scanning angles: -60° ≤ θ ≤ 60°, φ=360°. In this work, the frequencies are selected based on wider bandwidths and the lowest atmospheric gasses' attenuations for a 5G/6G communication system.

Wireless passive sensor based on the radio frequency identification (RFID) tag antenna has been widely used in structural health monitoring (SHM). The access of RFID technology to the 5G network is envisioned in 5G advanced technology. For the RFID tag sensor, the accurate and wireless determination of its antenna input impedance is a practical problem for ubiquitous sensing. In this paper, we propose a cost-effective wireless passive method for the measurement of tag antenna input impedance, which only requires an RFID reader and a low-complexity impedance tuning circuit. The proposed method can be used to track the impedance variation of RFID tag antenna for ubiquitous sensing.

This paper presents a low grating lobe lens loaded circularly polarized phased array with one wavelength element spacing at 28GHz band. The 2×2-element slot-coupled corner-truncated patch antenna is fed through a sequential feeding network, which, as a subarray, further forms a 4×4 phased array. A lens is placed above each patch sub array to suppress the grating lobe during the angle scanning. The results show that within ±15° scanning angle, the difference between the main lobe and the grating lobe remains below -11 dB within 25-31GHz. Besides, at broadside, the 3-dB axial ratio bandwidth is 21.4% and the aperture efficiency is above 60% in 19.9% bandwidth.

This paper proposes a modified scalable model considering kink effect for high-power Gallium Nitride (GaN) high-electron-mobility-transistors (HEMTs). Fixtures that can withstand high voltage and high current are designed to complete current-voltage (I-V) measurements of different sizes of high-power GaN HEMTs. Based on the measured I-V data, a scalable output current model including the kink effect is proposed. The scaling rule of the kink effect in GaN HEMTs with different sizes is studied and analyzed. The accuracy of the proposed scalable model is verified by applying the model to different sizes of GaN HEMTs.

This work presents dielectric waveguide power dividers based on multimode interference (MMI) in the sub-terahertz band. $boldsymbol{1}times boldsymbol{2}$ and $boldsymbol{1}times boldsymbol{3}$ power dividers are designed and simulated. The proposed power dividers include a feed dielectric waveguide, a transmission dielectric waveguide, and several output dielectric waveguides. It is investigated that the $boldsymbol{E}_{boldsymbol{11}}^{boldsymbol{x}}$ mode in the feed wave-guide excites the $boldsymbol{E}_{boldsymbol{n1}}^{boldsymbol{x}}$ mode in the transmission waveguide and then outputs the $boldsymbol{E}_{boldsymbol{11}}^{boldsymbol{x}}$ mode in the output waveguides. The proposed power dividers are composed of only one layer of dielectric material, which is simple in design and inexpensive. The proposed $boldsymbol{1}times boldsymbol{2}$ power divider has a center frequency of 100 GHz, the insertion loss of 0.9dB at 100GHz, the return loss greater than 26dB, and the isolation greater than 12.5dB at 86–120 GHz. The proposed 1 × 3 power divider has a center frequency of 100 GHz, the insertion loss of 0.75dB at 100GHz, the return loss greater than 25dB, and the isolation greater than 10dB at 93–118 GHz.

Compared with the first simplified design theory of the SiNx self-rolled-up membrane(S-RuM) radio frequency(RF) inductors, a more precise physical modeling is proposed and demonstrated in this paper. To eliminate the deviation between modeling and measurement data due to assumptions made in the original model, practical working mechanism including skin effect and nonuniform magnetic field distribution inside the tube are considered. The precision of the improved model is validated based on the fabrication of several S-RuM RF inductor samples with a wide range of dimensional parameters. By comparison, measurement data shows that at most 20% increment of precision has been achieved based on the proposed modeling.

The state of polarization (SoP) is one of the inherent properties of electromagnetic waves, and the important information they carry is indispensable in many applications. Conventional devices for measuring polarization states usually require complex measurement devices and cumbersome test procedures. Here, we present compact geometric phase metasurfaces consisting of a C-type cell in the millimeter-wave band, which can produce four focal points with different polarization states in the same focal plane. The intensity of the different focal points can be analyzed to determine the spin and ellipticity of the incident wave. Our device enables real-time polarization detection in the field of compact millimeter-wave polarization imaaing.
