Special Issue Information

Dear Colleagues,

In the context of increasingly complex electromagnetic environments, wireless systems such as communications and radar are facing severe interference challenges, which have become core bottlenecks restricting the improvement of system reliability, stability, and operational efficiency. Current anti-jamming research mostly focuses on isolated optimizations at the single level of algorithms or radio frequency (RF) front-end hardware, lacking a systematic collaborative design methodology that integrates system-level requirements, algorithmic mechanisms, and hardware implementation constraints. This disconnection leads to inefficient system development, difficulty in quantitatively decomposing overall anti-jamming indicators into component-level design specifications, and failure to achieve the global optimal performance of anti-jamming systems.

Against this background, the integration of algorithmic innovation with RF front-end hardware design has emerged as a critical research direction to break through the existing technical bottlenecks. This Special Issue aims to address the current separation between algorithms and RF front-end hardware design in anti-jamming research, promote the development of system-level collaborative design methods, establish a scientific decomposition and quantitative design system that maps system-level anti-jamming indicators to RF components (antennas, filters, frequency converters, etc.), and ultimately enhance the overall effectiveness and design efficiency of anti-jamming systems.

This Special Issue welcomes theoretical and practical contributions that advance the frontier of anti-jamming system design, with a focus on the integration of algorithms and hardware. We solicit original research articles and review articles covering innovative methodologies, technical implementations, and practical applications. Potential topics include, but are not limited to:

  • System-level collaborative design for anti-jamming systems;
  • RF front-end architecture and circuit design oriented to interference suppression;
  • Innovation in key anti-jamming components (e.g., anti-interference antennas, radomes, filters, frequency converters);
  • Adaptive and intelligent anti-jamming algorithms and their hardware-coordinated implementation;
  • Modeling, simulation, and test verification technologies for anti-jamming systems;
  • Quantitative decomposition methods of system anti-jamming indicators to component-level specifications;
  • Hardware-friendly optimization of anti-jamming algorithms;
  • Electromagnetic compatibility (EMC) design for anti-jamming RF front-ends.

We look forward to receiving your high-quality contributions and jointly promoting the innovation and development of anti-jamming system design technology.

Abstract
Simultaneous transmit-and-receive (STAR) antennas are important components of in-band full-duplex wireless front ends. However, transmit-to-receive leakage through the antenna limits the achievable antenna-domain isolation.

Simultaneous transmit-and-receive (STAR) antennas are important components of in-band full-duplex wireless front ends. However, transmit-to-receive leakage through the antenna limits the achievable antenna-domain isolation. This paper presents a dual-circularly polarized patch antenna incorporating a decoupling feeding network (DFN) to suppress the residual coupling between the transmit and receive ports. A stacked patch radiator with cross-aperture coupling generates right-hand and left-hand circularly polarized radiation from two separate ports. The DFN introduces an additional coupling path whose magnitude and electrical phase are adjusted to produce destructive interference near the target frequency. The fabricated prototype exhibits overlapping −10 dB impedance and 3 dB axial ratio bandwidths from 4.1 to 4.4 GHz, a minimum measured S21 of −50 dB, isolation higher than 30 dB from 4.25 to 4.28 GHz, and a peak realized gain of 7 dBic. The measured high-isolation range has an absolute bandwidth of 30 MHz and a fractional bandwidth of approximately 0.70% around 4.265 GHz. Therefore, the proposed DFN provides narrowband antenna-domain isolation enhancement around the designed frequency without requiring additional patterned decoupling elements on the radiating aperture. The proposed antenna is primarily intended for fixed-frequency or narrow-channel STAR front ends rather than broadband high-isolation operation. Full article
