Autotrack systems for space applications are typically based on monopulse. These systems require a specific test before being operative, typically through calibration towers, leading to expensive operating costs and antenna downtime. This work aims to present a technique to test in-lab these systems by the generation of high order modes as if they would be coupled using a calibration tower as well-known target. The theoretical working principle and a proof-of-concept design will be presented in Ku-band to confirm the reliability of the model.

In the recent years, thanks to possibilities opened up by the advancement of space technology, novel satellite architectures have been defined to shift the system complexity from the ground segment to on-board the satellite. One of the equipment that enables a high flexibility in the satellite, enhancing its ability to be reconfigured, is the beamforming function. A specific type of beamformer is the True-Time Delay (TTD) whose characteristic allows increasing the instantaneous bandwidth and FoV of the equipment allowing to support high data rate or high resolution applications. Within the RETINA program, the team lead by DAS Photonics with Airbus Italia, AMO, UPV and UKRI developed a reconfigurable multibeam photonic beamformer with centralised processing supporting a very innovative SAR approach based on photonic technologies. The BFN is based on an optimized PIC in silicon-nitride technology implementing designs of TTD beamforming network, suitable for broadband applications without beam-squint degradation and compatible with large antennas requirements. The flat Array Antenna is based on PCB technology with sub-array BFN integrated in the PCB. A breadboard of the Antenna System was developed and tested, and resulting performances show the ability of the system to fully support future EO SAR and Telecom systems.

The problem of evaluating the shielding effectiveness of a metallic circular disk with finite conductivity and finite thickness against a circular current loop coaxial with the disk is addressed. First the metallic disk is modeled through a new boundary condition which correctly takes into account the thickness of the disk and then the problem is reduced to only one set of dual integral equations which are solved in an exact form by expanding the spectral unknowns in a series of Bessel functions. The proposed formulation is compared with the one based on the Mitzner boundary conditions, showing its accuracy and the capability of reducing the computation time and with the one based on the thin-screen boundary conditions, showing that the latter can lead to erroneous results for sufficiently large thickness-to-skin-depth ratios.

In this work, a flexible narrowband fully passive printable multi-resonator is proposed for UHF RFID chipless tags working within the UHF band. The multi-resonator structure is flexible, has a compact size, a low cost of fabrication, and a very compact frequency bandwidth for each of the resonators, which unambiguously correspond to one stored data bit. The data can be encoded using spectral signatures, providing a unique ID for every tagged object. The multi-resonator has been designed using a general-purpose 3D CAD, CST Microwave Studio.

The present work was performed to expand the knowledge on human RF-EMF exposure, considering the use of mm-wave spectrum in mobile communication applications, due to the deployment of 5th generation (5G) networks. The mobile antenna was modelled based on the 5G innovation technologies (i.e., mm-Wave bands, beamforming capability and high gain), resulting in a phased array antenna with 8 elements at the working frequency of 27 GHz. Three different skin layers models were simulated, to spot differences in the peaks of absorbed power density averaged over 4 cm2, following the ICNIRP guidelines. The simulations were implemented using the Sim4Life platform, simulating not only the presence of a mobile phone user, but also of a person passing nearby, who could be hit by the phased array antenna main beam. This work underlined that the absorbed power density peaks were greatly underestimated using the homogeneous skin model, respect to the multi-layers skin models. Moreover, for the person passing nearby, we found slightly higher exposure levels than those assessed for the mobile phone user. Lastly, in all the examined cases, the limits indicated by the ICNIRP guidelines were well respected.

The exceptional properties of film bulk acoustic resonators (FBARs) such as low power consumption, high quality factors and high working frequencies make them the gold standard for radio frequency resonators. Once in the acoustic domain, the travelling waves frequencies become susceptible to the conditions of the propagating medium. In this context, their fabrication on flexible and wearable substrates represents a strategical step forward to obtain a new generation of highly sensitive sensors. In this work, we propose the fabrication and the characterization of an Aluminium Nitride-based FBAR directly fabricated on a flexible polymeric substrate. The fabrication process results very effective as the resonator shows a clear resonance around 1.56 GHz, a 3dB quality factor of 157 and can be integrated with antennas to accomplish a wireless sensor node.

This paper explores the use of the Cardiff non-linear behavioral model to characterize the response of multiple-input power amplifiers. In particular, a case study is presented on a 300 W load modulated balanced amplifier operating at 2.1 GHz. The model mathematical formulation is presented, and the comparison between original data and model shows an error below 3%. More importantly, it is shown that the model can accurately interpolate between characterization points allowing a reduction of up to 96% of the points needed to accurately predict the model behavior. This significantly reduces the simulation and measurement time for multiple-input PA's whilst attempting to determine the optimal driving conditions.

Radio frequency identification and sensing can benefit from the degrees of freedom offered by additive manufacturing processes, both bi-dimensional as well as three-dimensional ones. Moreover, the characterization of the electromagnetic properties of the involved materials plays an important role both in devising and designing innovative devices. The envisioned applications span from tags embedded in items to wearable sensors and metasurfaces adopted for enhancing probing signals into the human body.

This work reports the design of two key building blocks of a K/Ka-band SatCom phased-array transceiver. The circuits are developed by using 130-nm SiGe:C BiCMOS technology. A Ka-band single-ended Power Amplifier (PA) and a K-band single-ended Low-Noise Amplifier (LNA) have been designed. Simulation results have shown that the PA achieves 30.5 dB peak small signal gain, 27.6% peak power added efficiency (PAE), and an OIP3 better than 25 dBm within the entire operating frequency band. The maximum power consumption is 76 mW with a 2 V supply voltage, and it occupies an area of $1234 mumathrm{m}times 758 mumathrm{m}$, pads included. The simulations results of the LNA have shown 32 dB peak power gain, 2 dB minimum noise figure, and −18 dBm IIP3 at 20 GHz. The NF, in the entire frequency band of interest, is less than 2.3 dB. The LNA exhibits a power consumption of 20.7 mW with a supply voltage of 2.4 V and it occupies an area of $1000 mumathrm{m}times 800 mumathrm{m}$, pads included. It is worth noting that, a set of test structures that includes all the HBTs used for PA and LNA development have been designed and measured in order to evaluate both the accuracy of the models provided by the foundry and the impact of the extrinsic elements due to base, collector, and emitter interconnections.
