Alexandre B.

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.
