2.4 ghz ceramic antenna-SHENZHEN VLG WIRELESS TECHNOLOGY CO., LTD

Overview

This antenna is a passive ceramic antenna designed for GPS L1, L5 bands and Beidou B1 band, with excellent multi-band signal reception capabilities. It uses advanced ceramic materials and technologies to ensure efficient and stable signal reception in a wide frequency range (1176.45MHZ to 1575.42MHZ), meeting various high-precision positioning and navigation needs.

Key Features

• Wide frequency band coverage
The antenna covers frequency bands of GPS L1，L5 and Beidou B1, ensuring seamless switching and signal reception between different satellite navigation systems.

• Low standing wave ratio (VSWR)
In the specified frequency band, the standing wave ratio is ≤2.0, which helps to reduce signal reflection and loss and improve signal transmission efficiency.

• High gain
In the L5 band, the peak gain of the antenna is ≥1dB; in the L1/B1 band, the peak gain is ≥2.5dB, which helps to improve the strength and stability of signal reception.

• High efficiency
The antenna efficiency is ≥45%, which means that more signal energy is effectively received and converted into usable signals, reducing energy loss.

• Right-hand circular polarization (R.H.C.P)
Matches the polarization mode of the transmitted signal of most satellite navigation systems to improve signal reception efficiency.

• Miniaturized design
The compact size makes the antenna easy to integrate into various small devices, such as car navigation systems, handheld devices, etc.
