Special Issue Information

Dear Colleagues,

This Special Issue is intended to focus research toward disruptive technologies in the area of ​​microwave antennas and devices. In recent decades, a special effort has been made in high-frequency technologies, which has facilitated access to the manufacture of structures that years ago were only thinkable in theoretical terms or could only be built in low-frequency ranges. In this issue, we intend to focus on research carried out on new advances in applied electrodynamics, without restrictions of frequency range or applications per se. The main objective is to present new elements for the analysis and synthesis of antennas and radiating and guided mechanisms, as well as their laboratory tests and measurements. Advances in radar, miniaturization of antennas, new numerical methods for analyzing structures, new technologies for manufacturing, such as 3D printing, new limits in receivers’ sensitivity, new records in emitted power, links at high frequency, new topologies for beam scanning, and low profile antennas for satellite applications are some of the areas covered by this issue. The relationship with areas such as quantum electrodymanics or light-gravity interaction are also within the scope of this issue, together with all the applications reported.

Frequency diverse array-multiple-input multiple-output (FDA-MIMO) radar makes it transmit beam range–angle two-dimensional freedom by attaching a small frequency offset increment between the array elements. With the widespread use of digital radio frequency memory (DRFM) technology, it is able to delay the false target to any range bin and doppler unit by delaying and forwarding the radar transmits signals, resulting in the deceptive jamming effect of range dimension. To this end, based on the research of the existing main-lobe deceptive interference methods, this paper proposes a new improved MUSIC method based on the FDA-MIMO radar against deceptive jamming in the range dimension. Firstly, the range information of target and jamming is determined through spatial spectrum search by using the mismatch of jamming in the airspace position and range bin position, and then the process of range dimension deceptive jamming suppression is given. The simulation analysis results show that the proposed anti-jamming method can effectively mitigate against range dimension deceptive jamming. Full article
