“…In this section, the experimental verification of the proposed analogue feed-forward carrier recovery for an AFE, reported in [7,8], working in E-band downlink frequency range is presented. The transmitter and the synchronous receiver are set up in a back-toback configuration, where a W-band variable attenuator models the FSPL.…”

“…The wide bandwidth available at millimetre-wave (mmWave) frequency range together with the advances in transistor technologies in both transit frequency and power handling aspects has led to the definition of frequency range 2 for the 5G NR between 6 and 100 GHz as stated in [1,2]. Several research works have been carried out, showing the technological feasibility of mmWave analogue front-ends (FEs), with carrier frequencies of 28, 38, 60 and 73 GHz for access links [3][4][5][6] and backhauling [7,8] reaching data rates exceeding the 10 Gbps requirements of 5G NR. One bottleneck to realise the broadband wireless access and backhauling links using the mmWave FEs is the highly complex and power-hungry digital baseband signal processing (DSP).…”

An analogue modulation‐type independent feed‐forward carrier recovery approach for broadband wireless communication systems is introduced in this work. The focus is on the deliberately increased local oscillator (LO) signal feed‐through to the radio frequency (RF) port of the up‐converter in a direct conversion transmitter (TX). The strong LO feed‐through is used at the receiver (RX) side to demodulate the RF signal. The heart of the carrier recovery block is a narrowband bandpass filter (BPF) and a frequency divider‐by‐n operated in injection‐locking mode to the strong LO feed‐through. The proposed method is investigated through circuit level simulations; while its feasibility is examined via the successful demodulation of complex data with various modulation types up to 8 Gbps for an E‐band front‐end. This method can be used for transceivers working at high carrier frequencies as far as the realisation of frequency divider circuits and narrowband BPFs is technically feasible.

“…E‐band (71–76 GHz/81–86 GHz) has a light spectrum regulation worldwide and can provide an available bandwidth of 10 GHz. Additionally, the atmospheric attenuation of E‐band is only about 0.5 dB/km in clear weather conditions [ 4 ] . E‐band is a very promising frequency band for the next generation of air‐to‐ground wireless links [ 5,6 ] .…”

“…Millimeter wave and terahertz communications technology are continuously developed for ultra-high capacity communication [1−2] . Although higher frequency brings more available bandwidth, the wireless transmission distance is greatly limited by the path loss, atmospheric loss and rain attenuation in the millimeter wave and terahertz frequency bands [3] . Compromises must be made between low and high frequency.…”

This paper presents an E-band reflector antenna fed by dual circularly polarized feed system. Axial displaced ellipse reflector is adopted for high gain and low blockage mechanisms. The feed system mainly composed of orthomode transducer, iris polarizer and horn antenna, and possesses dual circular polarization. The orthomode transducer offers high isolation performance in broadband by double symmetry and the iris polarizer achieves phase shift by introducing discontinuities. In addition, the ridge and iris in the feed are optimized to be wide enough to fabricate and maintain good mechanical properties in higher frequency band. The entire antenna is simulated and fabricated. The measured gain of 45 ± 1.2 dBi corresponds to about 52% efficiency. The measured results of reflection coefficients less than −18 dB, isolation over 27 dB, axial-ratio value less than 2.3 dB are achieved from 71 to 86 GHz.

“…A terrestrial E-band link could be more easily impaired by shadow fading and earth curvature compared to other cases, such as aeronautics and air-to-ground communication. However, with the advance in antenna, high-power semiconductors, and advanced DSP techniques, various E-band communication systems with extensive coverage (tens of km) and high capacity (tens of Gbps) have been extensively emerging, both in terrestrial [ 3 , 4 , 5 , 6 , 7 ], and air-to-ground [ 8 , 9 ] scenario.…”

Long-range E-band communication with fiber-equivalent speed is emerging extensively as a critical technology in the next-generation communication. This paper firstly reviews the relevant progress in recent research. A brief survey is presented on high-speed, long-range E-band communication systems and their relevant techniques that are essential to the link design, including antenna, power amplifier (PA), channel, and digital baseband processing. In the second part, we review our recent field trial of a long-range air-to-ground E-band link, which maintains steady transmission from a slow-moving helium balloon to the ground station with a vertical dimension of 20 km. The improvement directions and future research topics are then discussed.
