The Airy beams have intrigued many researchers because of their unusual characteristics. There are few studies on Airy beams in the microwave field, and the devices currently used to create Airy beams are complex. So, in this paper, a scalar holographic metasurface is proposed to generate a one-dimensional Airy beam, which reduces the complexity of the generation device of the Airy beam. The simulation results at 12 GHz show this paper's proposed method's correctness.

A high-order-mode two-feed orbital angular momentum (OAM) patch antenna at Ka-band is proposed in this paper. The circularly polarized OAM patch antenna has an impedance bandwidth of 23.7% with more than 10-dB return loss. A vortex beam carrying $l=pm 1$ OAM mode is generated with a mode purity over 85% from 26.5 GHz to 33 GHz. Additionally, by loading a low-profile lens, the maximum gain can be improved from 6.7 dBic to 15.7 dBic, and the beam divergence angle converges from 37° to 6°.

A design method of the 3-dB waveguide-to-microstrip power dividers with wide isolated frequency band has been presented in this study. A new TaN film resistor on AIN ceramic substrate, which is not in contact with the microstrip probes, is designed in the waveguide to improve the isolation of the divider. The measured results show above 10 dB minimum isolation in the range of 28–37 GHz. In addition, the return loss is better than 15 dB at all ports, with an average loss of 0.57 dB. The isolation design for the divider proposed in this study can achieve a wide bandwidth without increasing loss.

This paper presents a pulse waveform control method for multiple harmonic eliminations of multilevel RF-PWM. By considering the waveform synthesis of arbitrary multiple 3-level pulses, possible parameter groups of the pulses are obtained to eliminate multiple harmonics and make the fundamental component proportional to the input envelope. Taking the third and fifth harmonic elimination of multilevel RF-PWM as an example, two 3-level pulse waveform control methods are obtained. Each method can generate two different signal waveforms which have different influences on the performance of the output signal. The feasibility of the two methods and the effect of two waveforms on the performance are verified by simulation.

In this paper, a compact integrated duplex filtering antenna is proposed based on co-shared substrate integrated waveguide (SIW) cavity. Firstly, a dual-mode TE102 and (TE201 modes) rectangular cavity with two input ports is utilized as a common feeding cavity to respectively contribute one transmission poles for each channel. And then, an additional square cavity with a rectangular ring slot is coupled from the lower feeding cavity for both dual-mode excitation and duplexing passband radiation. To verify the proposed concept, a prototype duplex filtering antenna is simulated. The duplex filtering antenna resonates at 7.27 GHz and 8.06 GHz with a low cross-polarization and a high gain of 5.82 dBi and 6.91 dBi, respectively.

In this paper, we consider the average symbol error probability (SEP) performance of a hybrid satellite-terrestrial relay network with non-orthogonal multiple access (NOMA) and decode-and-forward (DF) protocol. In particular, we derived the closed-form expression of the average SEP for both far-user and near-user in a satellite-to-terrestrial channel. Numerical results are presented to prove the correctness of the derived formulas and illustrate the effect of some pivotal factors on the average SEP of the considered system.

With the gradual maturity of 5G technology, the structure design and performance optimization of microwave filters have become one of the important research topics in the field of RF communication. In this paper, the metal micro-coaxial structure is used to design a bandpass filter with a center frequency of about 28GHz. The structure form of short transversal line is adopted, the order is 5, and the 3dB bandwidth is about 20.3%. In-band insertion loss is greater than -1.19dB, The out-of-band suppression is less than -47dB and -30dB in the frequency band larger than 38GHz and smaller than 18GHz, respectively. The voltage standing wave ratio at the center frequency is 1.0512. The metal micro-coaxial structure provides a high isolation degree for the filter, and the insertion loss is smaller than the same type of filter, which has good engineering application value.

In the past two years, the Fiber-to-the-room (FTTR) solution has been widely deployed, which provides strong support for the usage of indoor Q-band mmWave communication. To reduce the peak-to-peak ratio (PAPR) requirements of RF components, single carrier (SC) modulation is adopted by Q-band mmWave communication. For SC communication, the fractional sampling clock offset influences link quality a lot. By inserting zero correlation zone (ZCZ) sequences between data symbols and doing equalization in frequency domain, the clock offset could be compensated at certain degree. To further improve the performance, a fractional sampling clock offset compensation method is proposed here and maximum 5.2dB gain of Signal-to-Ratio (SNR) is achieved.

In this paper, a multi-layer transmission metasurface for high efficiency linear polarization (LP) conversion and beam control is proposed. The metasurface unit cell is composed of three layers of metal and two layers of dielectric. The top and bottom metal layers are orthogonal grids while the middle metal layer is C-shaped split ring. By altering the opening angle of C-shaped metal split ring, phase-gradient metasurface is proposed. Simulation results have proved that polarization conversion ratio (PCR) is above 90% and the beam of electromagnetic wave (EMW) can be refracted 30° at 10GHz, which is a good validation of the generalized Snell's law.

In this paper, a doubler chain with 13-dBm output power and 35-dBc fundamental rejection is proposed for 5G millimeter-wave application. A bandpass structure is introduced to achieve out-of-band rejection while obtaining a good matching between the doubler and the post-driver. Pre- and post-drivers are deployed in the doubler chain to reduce the power requirement of the local oscillator and obtain high output power at the second harmonic band. The test chip was fabricated in a 0.13-µm SiGe BiCMOS technology with a core size of 0.4 mm2. Measurements show that the doubler chain produces up to 13-dBm out-put power at an input power of 2 dBm. In the frequency band of 28–36 GHz, the fundamental rejection is better than 35 dBc and the third-harmonic rejection is better than 28 dBc.
