3G GSM Antenna China Manufacturer and Supplier

The following is a summary of the technical characteristics, selection points and application scenarios of 3G GSM antennas:
I. Core parameters and design features
‌Frequency band coverage‌
Mainstream products cover the 800-2100MHz frequency band, compatible with GSM/GPRS/3G networks, and some broadband models support 4G/5G multi-mode communications (such as 700-2700MHz antennas).
Typical operating frequencies include:
‌890-960MHz‌ (GSM low frequency band)
‌1710-1880MHz‌ (GSM high frequency band and 3G frequency band).

‌Gain and radiation characteristics‌
Ordinary models have a gain of 3-5dBi, which is suitable for short-distance communications (such as smart meters and car radios);
High gain design can reach 14dBi, and is equipped with a copper rod radiator to improve signal penetration, suitable for industrial data transmission, base station expansion and other scenarios.

‌Interface and expandability‌
Standard SMA male interface, supports coaxial cable extension (such as 3m/5m cable options), easy to connect to wireless modules or routers.
Magnetic suction cup base design, can quickly absorb metal surfaces (such as roof or chassis shell), no need to punch holes for installation.

Flexible PCB Design:
Some antennas, like the high-gain LTE 4G cellular flexible PCB antenna, are designed with flexible PCB material for greater versatility and integration into various devices.
Connector Options:
Different types of connectors, such as SMA (Subminiature version A) male connectors, are used to ensure compatibility with various devices.

Mounting Options:
Antennas are designed with various mounting options, including magnetic base mounts for external antennas and built-in connectors for PCB mounting.
In summary, 3G GSM antennas are essential components for mobile communication, and their production often involves PCB technology and various design options to suit different device and application needs.

III. Selection and deployment suggestions
‌Band matching‌
Give priority to dual-band antennas covering 900MHz/1800MHz to ensure compatibility with mainstream 3G GSM networks.
‌Gain and distance‌
5-8dBi gain is recommended for densely populated urban areas, and models with 10dBi or above can be selected for open areas.
‌Installation optimization‌
The magnetic base needs to be fixed on a metal plane (steel plate is best), and the antenna is placed vertically to maximize omnidirectional coverage.

Avoid being close to high-voltage equipment or large metal obstructions to reduce signal attenuation.
