Product Introduction
High Gain for Strong Signal
Boasts a typical gain of ≥5.0dBi, ensuring enhanced signal strength and transmission efficiency, ideal for applications requiring reliable wireless connectivity.
Stable Frequency Performance
Operates at a center frequency of 2450±3.0MHz with a minimum -10dB bandwidth of 60MHz, providing consistent performance across the working range.
RHCP Polarization
Features right-hand circular polarization (RHCP), which reduces signal interference and improves reception in environments with reflections, such as urban or industrial settings.
Low VSWR & High Return Loss
With a maximum VSWR of 2.0 within the bandwidth and return loss at center frequency ≤-15dB, it minimizes signal reflection, ensuring efficient power transfer.
Temperature Stability
Has a maximum frequency temperature coefficient of 20ppm/℃, maintaining stable performance even in varying temperature conditions.
Application scenarios
Payment Terminals: Stable connectivity in portable POS systems
Smart Factory Sensors: Reliable data transmission in metal-rich industrial settings
Medical Wearables: Secure links in compact health monitors
Logistics Trackers: Consistent performance in rotating RFID tags
Retail Kiosks: Interference-resistant operation in high-density environments
