5G Built-in & Rod Antenna China Manufacturer

Technical characteristics and industry applications of 5G built-in and rod-shaped antennas
I. 5G built-in antennas
‌Design and integration optimization‌
Built-in antennas are mostly in the form of flexible printed circuits (FPC) or PCB boards, and use structures such as planar inverted F-type (PIFA) to achieve compact layout. Bijvoorbeeld, Shenzhen Boges’ 5G built-in FPC antenna group adapts to the internal space limitations of the device through flexible materials, while supporting multi-band coverage.
In the design of Maya Communication’s 5G mobile phone antenna, the multi-frequency function is realized through the U-shaped slot structure, and the coaxial feeding technology is combined to reduce the return loss and enhance the signal matching ability.

Function: Built-in antennas are designed to be compact and efficient, fitting within the confines of devices like smartphones. They typically use techniques like beamforming and MIMO to improve signal quality and range.
Examples: Smartphones, tablets, and other portable devices.
Considerations: Antenna design in small devices requires careful consideration of placement, ground plane, and other factors to ensure optimal performance across different frequency bands and technologies.

‌Performance Improvement‌
Shanghai Shengdana’s full-band high-gain 5G antenna achieves full-band coverage and efficiency improvement by symmetrically arranging the mid- and low-frequency band boards and the high-frequency body, while reducing the cost of the reflector.

The size of the built-in antenna of modern smartphones has been significantly reduced with the high-frequency band (GHz) technologie, but it still needs to ensure the efficiency of signal transmission and reception through impedance matching and electromagnetic field optimization.

‌Application Scenario‌
Mainly used in smartphones, IoT terminals and miniaturized communication devices, such as the 5G-MIMO antenna solution provided by Shenzhen Boges is suitable for smart wearables and industrial sensors.

III. 5G Rod Antenna
‌Structure and Material Properties‌
Rod antennas are mostly external, made of copper tube or fiberglass, and use a quarter-wavelength oscillator design to optimize signal radiation efficiency57. Bijvoorbeeld, Zhongjing Communication’s 5G rubber rod antenna covers the 800-5000MHz frequency band, with a gain of 5dB, suitable for outdoor environments.
Renfeng Electronics’ suction cup antenna combines a waterproof design to support 5G high-frequency band signal transmission and is often used in vehicle or ship communication scenarios.

Rod Antennas (and External Antennas):
Function:
Rod antennas, also known as pole antennas, are external antennas that can be attached to devices or installed separately. They are often designed to have a higher gain than built-in antennas, allowing them to capture and transmit signals more effectively.
Examples:
Omnidirectional antennas (like those from Cisco) and directional antennas.
Benefits:
Improved signal strength, extended range, and enhanced connectivity in areas with poor 5G coverage.

‌Low cost and easy deployment‌
The manufacturing process of rod antennas is mature. Manufacturers (such as Zhongjing Communication) have achieved a unit price as low as 2.66 yuan through large-scale production, and are compatible with a variety of interfaces (such as SMA).
Users can make their own antennas based on the wavelength formula (300/frequency ÷ 4×0.96), such as using air conditioning copper tubes to make high-power rod antennas to improve signal strength.

‌Typical Applications‌
Widely used in routers, base station extension equipment and vehicle communication systems, supporting high-gain demand scenarios (such as long-distance signal transmission).
Used in various applications, including public safety vehicles, fleet vehicles, and IoT applications where space is limited.

‌Selection Recommendations‌: If the device needs to be miniaturized and support multiple frequency bands, internal antennas are preferred; if signal gain and deployment flexibility are emphasized, rod antennas are more advantageous.

Considerations:
Rod antennas may require a direct coaxial wired connection to a modem or router for proper function.
In summary: 5G antennas, both built-in and external, play a crucial role in enabling high-speed, low-latency connectivity. Built-in antennas are designed for compactness, while external antennas offer higher gain and improved coverage in specific situations.
