“…Because of their broadband properties, high-range resolution, and penetrability, the UWB radars can also be used in the field of noninvasive diagnostics and detection of human vital sign signals such as respiration and heart rates [ 17 , 18 , 19 ]. These systems are used for many other fields, such as nondestructive testing and industrial areas [ 20 ], automotive industry [ 21 ], impedance spectroscopy [ 22 ]. Other interests lie in the areas of Internet of Things and Industry 4.0.…”

In this paper, the recent progress on sinuous antennas is detailed, focusing the attention on the antenna geometry, dielectric structure, and miniaturization techniques. In the first part, we introduce the basic principles of the frequency-independent antenna, in particular the self-complementary and log-periodic geometries, as well as the antenna geometries, all characterized in terms of angles. The operating principles, main advantages, system design considerations, limits, and challenges of conventional sinuous antennas are illustrated. Second, we describe some technical solutions aimed to ensure the optimal trade-off between antenna size and radiation behavior. To this aim, some special modification of the antenna geometry based on the meandering as well as on the loading with dielectric structures are presented. Moreover, the cavity backing technique is explained in detail as a method to achieve unidirectional radiation. Third, we present a new class of supershaped sinuous antenna based on a suitable merge of the 2D superformula and the sinuous curve. The effect of the free parameters change on the antenna arm geometry as well as the performance improvement in terms of directivity, beam stability, beam angle, gain, and radiating efficiency are highlighted.

Short-range ultra-wideband (UWB) radar sensors belong to very promising sensing techniques that have received vast attention recently. The M-sequence UWB sensing techniques for radio detection and ranging feature several advantages over the other short-range radars, inter alia superior integration capabilities. The prerequisite to investigate their capabilities in real scenarios is the existence of physically available hardware, i.e., particular functional system blocks. In this paper, we present three novel blocks of M-sequence UWB radars exploiting application-specific integrated circuit (ASIC) technology. These are the integrated 15th-order M-sequence radar transceiver on one chip, experimental active Electronic Communication Committee (ECC) bandpass filter, and miniature transmitting UWB antenna with an integrated amplifier. All these are custom designs intended for the enhancement of capabilities of an M-sequence-based system family for new UWB short-range sensing applications. The design approaches and verification of the manufactured prototypes by measurements of the realized circuits are presented in this paper. The fine balance on technology capabilities (Fc of roughly 120 GHz) and thoughtful design process of the proposed blocks is the first step toward remarkably minimized devices, e.g., as System on Chip designs, which apparently allow broadening the range of new applications.

This article describes phase noise measurement of a designed ASIC voltage-controlled oscillator in 0.25 µm SiGe BiCMOS technology, with frequency synthesizer ADF4002 from Analog Devices. The oscillator topology utilized in this design is based on a crosscoupled-transistor configuration, and it incorporates two options for frequency control: varicap and capacitor bank. The oscillator frequency is 11.13 GHz with an adjustment frequency range around ±250 MHz. Phase noise measurements were performed on a custom evaluation board. Oscillator with PLL achieves phase noise λ(100 kHz)= -70 dBc at f c = 11.1353 GHz. The article contains phase noise measurement of ASIC comparisons based on selected parameters, dividers and ADF4002 settings. Comparison with the commercial oscillator TGV2566SM and PLL ADF4002 is introduces as well. Details of the measurement setup and different filter parameters are discussed.
