This paper presents the millimeter-wave (mmWave) propagation characteristics and statistical channel model parameters at 28 GHz for fifth generation (5G) wireless communication systems. The propagation characteristics of mmWave signal in the cross-corridor environments are analyzed based on the method of shooting and bouncing ray tracing/image (SBR/IM). Propagation characteristics, including path loss models, root-mean-square (RMS) delay spread, Ricean K-factor, and correlation coefficients between channel parameters are investigated. Moreover, path loss models are established for the cross-corridor channel. Results show that the path loss exponents (PLEs) vary between 1.37 and 1.75 for line-of-sight (LOS) scenarios and the PLEs vary between 2.90 and 5.09 for non-line-of-sight (NLOS) scenarios. The statistics of channel parameters are useful for 5G communication system development and deployment.

This paper designs a wide-angle frequency scanning metamaterial (MTM) leaky wave antenna (LWA) array for automotive radars. The gap capacitors and the vialess open stub-loaded resonators are used to construct the frequency scanning MTM LWA array. the propagation constant of the MTM LWA array is able to change from negative to positive values as the frequency is increased, resulting in backward to forward beam scanning. Compared to mechanical beam scanning arrays and phased arrays, the frequency scanning MTM LWA arrays have advantages of reducing the system complexity, light weight and low cost. The presented MTM LWA array has a maximum gain of 13 dB and wide scanning angle from −60°to +80° as the frequency varies from 23.5 to 25.6 GHz which is well suited for automotive radar applications.

A filtering antenna is proposed with substrate integrated waveguide and patch resonators in low temperature co-fired ceramic. It is design with the topology of coupled resonators embedded with a lowpass filter. Due to the two 45-degree linearly polarized patches, the measured gain is 7.0 dBi with the 3-dB beamwidth of 48° and the antenna efficiency of about 70% around 28 GHz. The passband bandwidth is over 2.5 GHz. The out-of-band rejection can reach 18 dBc up to 40 GHz. According to the stacked antenna-in-package form, the volume of the overall component is only $12times 6times 1.6 mathrm{mm}^{3}$.

This work presents a CMOS power amplifier (PA) for FDD (band 17, 18, 19 and 20) of 4G cellular applications. In this work, a power cell by using three stacked transistors is proposed. It not only meets the breakdown voltage requirement, but also provides enough power gain and output power. By designing the compact and low-loss layout of the power cell, the power added efficiency (PAE) is increased observably. It is fabricated in 180-nm CMOS with a chip area of $1800 mu mathrm{m} times 1500 mu mathrm{m}$. The proposed PA achieves a power gain of 37 dB, saturated output power $(mathbf{P}_{mathbf{s}mathbf{a}mathbf{t}})$ of 32 dBm, output 1 dB compression point $(mathbf{OP}_{mathbf{l}mathbf{d}mathbf{B}})$ of 30.5 dBm and peak PAE of 41.50/0 at 810 MHz.

A wideband and circularly polarized (CP) substrate integrated cavity-backed patch antenna is proposed. This antenna has a wide-beam radiation pattern. The half power beam-width (HPBW) is 154° and the axial ratio (AR) below 5.8dB is more than 229° in both $mathbf{phi}=pmb{0^{circ}}$ and $mathbf{phi}=pmb{90^{circ}}$ planes, which has a large potential for CP wide-angle scanning phased array. The impedance bandwidth with SII $< pmb{-10}mathbf{dB}$ is more than 23%. An $pmb{8 X 8}$ planar phased array based on the antenna element is designed. The simulated results show that the main beam can scan from -60° to + 60° with 3dB gain fluctuation and from -80° to + 80° with 6.5dB gain fluctuation. Meanwhile, the AR is smaller than 3dB within the scanning range from -60° to + 60°, and smaller than 6dB within scanning range from -80° to + 80°.

An optically transparent broadband RFSS absorber, with wide incident angle range was demonstrated based on ITO films. Equivalent TLM and full-wave electromagnetic simulation were used to analyze and optimize the absorber. The experimental results agree well with calculated ones. Specifically, the bandwidths of absorptivity $geq 80%$ under incident angle 45° are over 9GHz for both TE and TM polarization, respectively.

We present a 3D printed metallic K-band (18-26.5 GHz) passive frontend for satellite communication. Taking the advantage of the 3D printing technology in realizing complex structures, we achieve a highly-integrated passive module. Good agreement is achieved between simulation and measurement. The proposed frontend has impedance bandwidth 19 - 21 GHz, the maximum gain of 15.5 dBi at 21 GHz, and desirable radiation patterns on both E- and H-planes. Compared with traditionally fabricated metallic microwave passive devices, the proposed work has a shorter turn-around time and a lower cost. Compared with dielectric 3D printed microwave devices, it features more simplicity in terms of process and better physical robustness. It opens up new possibilities for microwave device fabrication.

A load-pull based method was used to achieve the best load matching impedance for a VHF band complementary metal oxide semiconductor (CMOS) power amplifier (PA). With the employ of the new technique, PA designers can not only target the load impedance area which provides the maximum output power, but also can maintain the PA with the best output third-order interception point (OIP3). Both schematic and post-layout simulations are provided to validate the effectiveness of the new technique.

In this work, a novel broadband polarization conversion metasurface (PCM) with high polarization conversion ratio is presented for radar cross section (RCS) reduction. The reflection phase difference of the PCM unit cell and its mirror is about 180°in a broad frequency band. Based on the phase cancellation and diffuse reflection theory, a broadband RCS reduction is achieved by designing the layout of the unit cells of the metasurface. The simulation results show that the proposed metasurface can significantly reduce the RCS more than 10 dB from 7 GHz to 20 GHz (i.e., fractional bandwidth 96.3%) comparing with the same size bare metal plate. The proposed metasurface with low profile and simple structure shows great potential applications in stealth technology.

The antenna is composed of compact square microstrip patch antenna elements with series feed. The character of high gain origins from the configuration of the microstrip antenna arrays, and the character of low side-lobe is obtained by Taylor synthesis method. The validity of the method is confirmed by computer simulation and experiments. The gain of the antenna array is 21.4dB and the side-lobe lever is less than -24dB, illustrating the feature of high gain and side lobe, which can be used in monitoring system of traffic [1].
