433MHz Flexible PCB Antenna for IoT & Remote Control

Product Introduction

1. Optimized for the 433MHz ISM Band: Precisely tuned to the globally universal, unlicensed 433MHz band, providing a stable and efficient wireless connectivity solution for IoT data transmission, remote control, and automotive applications.

2. Compact and Flexible Square Design: The ultra-thin, flexible PCB structure, measuring only 20x20mm, easily adapts to the internal space of various compact devices, greatly facilitating miniaturization and lightweight design.

3. Excellent Signal Transmission Efficiency: Voltage Standing Wave Ratio (VSWR) ≤1.5, indicating extremely high antenna-circuit matching, minimizing energy loss during signal transmission and improving communication distance and reliability.

4. Dual Connection Options for Easy Integration: Offers both standard IPEX connectors (for easy cable connection) and direct soldering interface options, flexibly adapting to different manufacturing processes, cost budgets, and product structure design requirements.

5. High Power Handling and Durability: Supports a maximum input power of up to 20W, far exceeding the transmission requirements of typical 433MHz devices, ensuring stability in high-power applications. Flexible materials are robust and durable, capable of withstanding stress during assembly and use.

FAQ

Q: Does this antenna support other frequency bands, such as 868MHz or 915MHz?

A: No. The GLFPC079 is a single-band antenna specifically designed and optimized for the 433MHz band. If you require other ISM bands, please refer to our other FPC models.

Q: Should I choose IPEX connection or direct soldering?

A: This depends on your manufacturing process. IPEX connectors facilitate assembly, testing, and repair, making them suitable for most mass production applications. Direct soldering provides a stronger physical connection and lower cost, ideal for designs with extremely limited space or high connection strength requirements.

Q: What precautions should be taken when mounting on a PCB?

A: To ensure performance, always place the antenna on the edge or corner of the PCB and strictly adhere to the datasheet requirements, leaving sufficient clearance below the antenna's projection area (ground plane) to avoid obstruction by metal or batteries.

Q: Is 3dBi gain sufficient?

A: For the 433MHz band and small antenna size, 3dBi is a typical practical gain value for omnidirectional antennas. It strikes a good balance between communication distance, signal coverage, and physical size, meeting the needs of most IoT and remote control applications.

Q: What is the radiation pattern of this antenna?

A: It is an omnidirectional antenna, achieving uniform 360-degree radiation on a horizontal plane, making it ideal for applications where the device orientation is not fixed or requires communication in all directions.

Q: What is its operating temperature range? 

A: Standard commercial-grade FPC antennas typically operate in a temperature range of -20°C to +70°C. For more extreme industrial or automotive-grade temperature requirements, please specify this when selecting a model.
