Overview
The dual-band internal ceramic antenna is a high-performance antenna solution that combines the excellent properties of ceramic materials with dual-band working capabilities. It is widely used in multiple fields and plays an important role in wireless communications and navigation and positioning.
Key Features
 |
 |
 |
|
High temperature resistance and weather resistance The ceramic material has good high temperature resistance and weather resistance, allowing the antenna to maintain normal operation in harsh environments. |
Good frequency stability The dual-band built-in ceramic antenna can maintain its operating frequency unchanged over a large temperature range, which is very suitable for high-precision measurement, positioning and other fields. |
Miniaturization and high integration The dual-band built-in ceramic antenna has a small size and weight, which is easy to install and integrate inside the device, improving the overall aesthetics and portability of the device. |
Parameters
Available in different sizes：
| Ceramics Size（mm） | Freq. Range(MHz) | Axial Ratio | Polarization | VSWR (dB) | Gain | working temp. |
| 25X25X4+18X18X4 | L1 1575.42±1.023 | ≤3dB | RHCP | ≤2 | ≥1.0dBi | -40~+85℃ |
| L5 1176.45±1.023 | ||||||
| 38X38X6+25X25X4 | L1 1575.42±1.023 | ≤3dB | RHCP | ≤2 | ≥2.5dBi | -40~+85℃ |
| Note: Antenna size above 38X38, the default design is doubly-fed four needle, can be changed into single feed single needle, single feed double needle, doubly-fed double needle as required . | ||||||
Applications
It can be integrated into scooters, shared bicycles, vehicle navigation systems, drones and aircraft equipment, intelligent robot systems, outdoor adventure and positioning equipment to provide users with stable signal reception and precise positioning services.
