“…After the feasibility of the concept of electrically short active antennas for M-sequence UWB radars was confirmed by the experiments with discrete components in our previous work [ 54 ], customized ASIC circuits were proposed. The receiving short dipole UWB antenna for M-sequence radar application together with its ASIC amplifier design was proposed in [ 55 ]. The design of the transmitting antenna driver ASIC, as well as the design of a miniature active antenna exploiting it, will be shown in this section.…”

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.

“…An ultra-small antenna for UWB radars operating at frequencies from 1 to 9 GHz was also proposed, which exploits a simple electrically short dipole printed on a PCB material with an integrated differential amplifier placed directly in the centre of the dipole [17].…”

“…[16] Figure 25. Smith chart S11 and S21 of the amplifier performances [17] The performance of the final antenna prototype was measured and compared to a professional antenna. From the results one can conclude that the antenna dimensions and weight, see Figure 25, has been successfully reduced by a factor greater than 10, while the characteristics of the antenna dropped by less than 10dB, dependent on frequency.…”

Nowadays, the interference cancellation or mitigation plays a key important role in the effective use of the advanced radar technology. This article is focused on the symposium presentations related to Electromagnetic Spectrum Operations (EMSO) of the radar systems. The modernisation of the Hungarian Army, the success of the Zrínyi 2026 program, basically depends on the understanding and the professional service of new technologies during their lifecycle. In civilian applications, the inter-radar interference of automotive radars is an emerging problem for automotive radar applications in case of dense deployment. Consequently, it is a priority task to gather, evaluate and transfer collected expertise on the advanced research findings and concepts related to emerging sensor technologies. It looks like the permanent engineering/scientific policies should be implemented to monitor and maximise radar performance to support safety measures required within EMSO. The article summarises the most recent results of the radars taking into account the domesticexpectations.
