I specialize in advanced RF and antenna engineering, combining deep theoretical expertise with practical prototyping and laboratory validation. My experience includes antenna design and miniaturization, low-noise amplifiers, active and reconfigurable antennas, RF and microwave sensors, analog RF design, full-wave simulation (using licensed CST Studio Suite), prototyping, lab testing, and regulatory certification support. My primary focus areas include antennas and RF systems for: Mobile and wearable devices Drones and autonomous platforms Аnti-drone air defense Smart and electrically small antennas Super-directive and high-directivity antennas X-wave launchers Medical imaging MIMO, beamforming, and beam-steering systems Real-time location systems (RTLS) and asset tracking Cellular systems (LTE, O2, 5G) IoT technologies: RFID, NFC, LoRa, Wi-Fi, BLE Radar and sensing systems High-speed and RF PCB design, signal integrity, and EMC/EMI compliance Sub-millimeter-wave and ultra-high-frequency interconnect solutions Electronic countermeasure resilience: jamming/anti-jamming and EMP/electromagnetic-burst immunity. Engineering & Consulting Services I provide full-cycle technical consulting and development support, including: Concept development and system architecture RF and antenna design & optimization Simulation-based verification (CST) Rapid prototyping and performance testing Troubleshooting and performance improvement of existing designs Regulatory pre-compliance and compliance support (FCC, CE, KC) RF measurements and diagnostics PCB reverse engineering and design recovery Laboratory Capabilities I operate with access to a professional RF laboratory equipped with: Vector Network Analyzer (VNA) Spectrum Analyzer EMI/EMC test equipment Anechoic chamber PCB fabrication tools SMT assembly and rework systems Technical Writing & Research Support In addition to engineering services, I provide support for technical and academic writing, including: Scientific papers and journal submissions Technical reports and documentation Extended essays, theses, and dissertations Research proposal development and hypothesis formulation Proofreading and technical editing My assistance spans from developing research concepts and outlines to final technical review and editing for publication.
