Product Introduction of RF Cables Matched with Built-in Antennas

I. Product Overview

RF cables are special wires dedicated to transmitting high-frequency RF signals, which are often matched and assembled with built-in antennas. The complete integrated assembly integrates antenna receiving/transmitting modules and RF transmission lines. No protruding external antenna is required, delivering a neat and compact device appearance. It is widely applied to GPS, Wi-Fi, Bluetooth, vehicle navigation, IoT terminals, smart home appliances, communication modules and other equipment.The all-in-one integrated design saves customers separate wiring and antenna assembly procedures, lowers overall equipment assembly difficulty and saves internal space of devices.

II. Core Structural Components

Main Body of Built-in Antenna

Miniaturized solutions including FPC flexible antennas, ceramic antennas and PCB patch antennas are adopted, concealed inside equipment housings without exposure, dustproof and collision-resistant. Customized development for different frequency bands supports receiving and transmitting RF signals of GPS/Beidou, 2.4G/5G Wi-Fi, 4G/5G.

RF Coaxial Cables

Ultra-fine coaxial cables (0.81mm, 1.13mm and other specifications) are commonly used with stable 50Ω characteristic impedance, low signal loss and high shielding performance. The inner conductor transmits RF signals, while the outer shielding layer isolates electromagnetic interference to ensure stable signal performance.

RF Connectors

RF connectors such as IPEX, SMA and MMCX are soldered at cable ends for direct connection with mainboard communication modules. They feature stable plug-and-play performance and match various mainboard interfaces of terminals.

III. Product Advantages

Concealed Built-in Design

The built-in antenna has no protruding structure, realizing integrated equipment appearance with waterproof and dustproof performance, suitable for portable devices, automotive equipment and mini smart hardware.

Low-Loss RF Transmission

Special RF coaxial cables boast outstanding shielding capacity with slight signal attenuation during long-distance wiring and strong EMI resistance, preventing signal disturbance from internal circuits of equipment.

Miniaturized & Easy to Assemble

Ultra-thin antennas and slim bendable cables fit narrow internal space of devices. Finished integrated assemblies are delivered to greatly improve overall assembly efficiency.

Customization for Multi-Band Compatibility

Single-band or dual-band antennas can be customized as required to meet different RF demands including GPS positioning, wireless local area network and mobile communication. Cable length and connector specifications are adjustable on demand.

Stable and Reliable Signal Performance

Integrated soldering of antennas and RF cables reduces contact impedance and signal breakpoints, delivering smooth positioning and wireless connection without signal drift.

IV. Main Application Scenarios

• Vehicle navigation systems, dashcams (GPS & Beidou positioning antennas)

• Wireless cameras, smart home gateways (Wi-Fi & Bluetooth antennas)

• IoT modules, industrial data collection terminals

• Built-in wireless modules for tablets, laptops and mini industrial control hosts

• Outdoor smart equipment, portable testing instruments

V. Summary of Application Features

The integrated assembly of RF cables and built-in antennas solves the pain points of traditional external antennas such as large space occupation, easy damage and severe signal interference. Balancing appearance, space utilization and RF transmission performance, it has become the mainstream supporting cable assembly for mini wireless communication equipment.
