Full Band Anti-Drone Omni Antenna
Background:
A Chinese security company turned to us for a cutting-edge, full-band omnidirectional antenna tailored for UAV detection and neutralization. This antenna was tasked with handling input power surpassing 300W while ensuring a complete 360-degree surveillance and response capability against drones. The client's specifications were precise, requiring an antenna that could adeptly navigate a vast array of frequencies with a form factor that remained sleek and manageable.
Challenges:
Crafting an Anti-Drone Omni Antenna to cover a spectrum of frequencies—433MHz, 868MHz, 915MHz, 1.2GHz, 1227.60MHz, 1575.42MHz, 2.4GHz (2400-2500MHz), and 5GHz (5150-5850MHz)—without a substantial size increase was the central hurdle. The design had to be both robust and discreet, a delicate balance to achieve.
RF element's Solution:
Our engineering team tackled this challenge by drawing on past successful projects:
1. Antenna Design Innovation: We divided the design into four full-bandwidth sector antennas, each operating across the entire specified frequency range.
2. Sector Antenna Configuration: Each sector antenna was designed with a 90-degree horizontal beamwidth, ensuring 360-degree coverage when combined.
3. Power Handling and Gain Optimization: The antenna was engineered to handle over 300W while maintaining high gain across all frequency bands.
4. Compact Design: A key aspect was keeping the antenna compact for easy installation and minimal physical footprint.
Design and Development:
The development process included:
1. Frequency Band Integration: Our engineers selected materials and components that could support the broad frequency range without compromising performance.
2. Antenna Gain and Pattern Tuning: Extensive simulations and testing were conducted to optimize the antenna gain and ensure uniform radiation patterns across all bands.
3. Rigorous Testing and Refinement: The full band anti-drone omni antenna underwent days of tuning and refinement to meet the client's performance criteria.
Final Product:
The final product was a full band anti-drone omni antenna that met all the client's requirements, including power handling, gain, size, and installation considerations.
