In this work, a millimetre wave receiver prototype integrating a graphene based subharmonic mixer and a diagonal horn antenna is presented. The block receives a millimetre wave signal in the WR-5 frequency band (140-220 GHz), which is downconverted using a high-order harmonic component of the local oscillator signal, in the WR-28 frequency band (26.5-40 GHz), producing an IF output at 300 MHz. A prototype has been manufactured using high precision 3D printing techniques. The performance for subharmonic orders 6, 8 and 10 has been evaluated through preliminary measurements in the neighbouring WR-3 frequency band. Measured radiation patterns are also presented.

A loaded antipodal linear tapered slot antenna (ALTSA) with a diamond-shaped slot is presented. The feed system is implemented using a substrate integrated waveguide (SIW), tapered microstrip-to-SIW transition and a horn-shaped via. The proposed antenna exhibits a return loss better than 18 dB over the band of interest (50-70 GHz) with a gain of 16.2 dB at the center frequency. The overall efficiency is 94%. Rectangular corrugation is employed to improve the radiation pattern. The ALTSA and the feed system all have been designed on a single layer substrate, resulting in a low-cost compact antenna which is suitable for 60 GHz wireless applications.

This paper reviews the technology requirements of future mm-wave systems-on-chip and the challenges facing mm-wave MOSFET and SiGe HBT device and benchmark circuit scaling towards 3nm gate length and beyond 1.5THz fMAX. Measurements of state-of-the-art MOSFETs, HBTs and cascodes are presented from DC to 325 GHz. Finally, simulations of the scaling of the SiGe HBT mm-wave benchmark circuit performance across future technology nodes predict that PAs with 45% PAE at 220 GHz, and transimpedance amplifiers with over 175GHz bandwidth and less than 3dB noise figure will become feasible by the year 2030.

In this work, a fully Textile Integrated Waveguide (TIW) beamforming antenna for its use in a radar system operating at 77 GHz is presented. The TIW beamforming antenna is based on a Substrate Integrated Waveguide (SIW) slot antenna array and it is designed to be manufactured completely with conductive and non-conductive threads using industrial textile machinery, avoiding subsequent sewing and adhesive processes for its integration in wearable or comformable systems. The antenna performs beam tilting from 11 to 23 degrees in the H-plane while sweeping the frequency from 70 GHz to 77 GHz. Firstly, a design of the equivalent SIW beamforming antenna structure is simulated and optimized and then, the translation into a fully woven TIW beamforming antenna structure is presented. The proposed TIW beamforming antenna design is provided with a TIW to WR10 standard rectangular waveguide transition for its experimental validation.

In this paper, a novel broadband antenna array is presented. The radiating element is a unique via-fed U-shaped patch element with a distribution network based on offset stripline technology. The feed position has been deliberately designed for optimized matching taking into account the design rules of a low cost PCB mass production technology. The radiating element has a 3-dB beam-width of ±30 degrees in both planes making it suitable for beam steering. To show the validity of the approach, a 2×2 array prototype is presented in this paper. The antenna array is approximately 12mm×12mm in size realized on a Rogers 4350 substrate. The antenna has been optimized for the 24-34 GHz frequency range. Simulated and measured return loss, radiation pattern and gain over frequency have been presented. This antenna structure is a good candidate for steerable phased arrays in 5G millimeter wave applications.
