Adopting FPC material, the thickness is usually less than 0.2mm, which can be bent and folded to adapt to complex space layouts, especially suitable for miniaturised and thin and light devices (e.g., smart home, wearable devices).
Lightweight, reducing the burden on the overall structure of the device, and easy to integrate.
Optimised for 433MHz band, supports Sub-GHz wireless communication protocols (e.g. LoRa, ISM) to meet the demand for low power consumption and long distance transmission.
In open environments, the communication distance can reach hundreds of metres, suitable for Internet of Things (IoT) scenarios.
Can be directly mounted on PCB boards without additional brackets or housings, simplifying the production process.
Supports surface mount technology (SMT) and is suitable for automated production lines, reducing manufacturing costs.
FPC material is corrosion-resistant, anti-aging, and can adapt to high temperatures, humidity, and other harsh environments.
Impedance matching design (e.g., 50Ω) reduces signal reflection and improves transmission efficiency.
Antenna size, shape, and feed point position can be adjusted according to equipment requirements to optimise radiation performance.
Supports multi-band compatible design (e.g., 433MHz+470MHz) to expand application scenarios.
etc.
Smart sockets, lighting control, and security sensors.
Environmental monitoring, asset tracking, and equipment status monitoring.
Wearable devices, remote health monitoring.
Soil moisture sensor, weather station.
etc.
A flexible 433 MHz PCB antenna is thinner, lighter, lower cost, and suitable for large-scale deployment.
