Product Introduction
Stable Center Frequency: The GL916R35 operates at a center frequency of 916.0 ± 3 MHz, ensuring consistent signal transmission and reception within a narrow frequency range. This stability is crucial for applications that require precise frequency tuning, reducing the risk of interference and signal loss.
Adequate Bandwidth: With a -10dB bandwidth of at least 26 MHz, the antenna can cover a relatively wide frequency range. This allows it to support multiple channels or data streams, making it suitable for applications that demand high - capacity communication, such as wireless sensor networks with multiple nodes.
Low Return Loss and VSWR: The return loss at the center frequency is less than -15dB, and the VSWR (Voltage Standing Wave Ratio) within the bandwidth is at most 2.0. These values indicate efficient power transfer and minimal signal reflection. A low return loss and VSWR result in better signal quality and more reliable communication, ensuring that the antenna can effectively transmit and receive signals without significant loss.
Right - Hand Circular Polarization (RHCP): The GL916R35 features RHCP polarization. This type of polarization offers several advantages, including reduced interference from multi - path signals and better signal penetration through obstacles. It is particularly useful in complex electromagnetic environments, such as urban areas or indoor spaces with many reflecting surfaces.
Low Frequency Temperature Coefficient: With a frequency temperature coefficient of 20ppm/deg.℃ max, the GL916R35 is less affected by temperature changes. This means that its performance remains stable across a wide range of temperatures, making it suitable for both indoor and outdoor applications, including harsh environments where temperature variations can be significant.
Application scenarios
Smart Agriculture: Ensures reliable data transmission in soil sensors exposed to varying weather.
Industrial IoT: Maintains connectivity in factory automation systems with electromagnetic noise.
Medical Devices: Delivers stable signals for wireless patient monitoring equipment.
Utility Metering: Provides long-term accuracy in smart water/gas meters.
