1. The Importance of Choosing the Right PCB Material

Selecting the appropriate PCB material is critical in PCB antenna design, especially for IoT applications. The choice of material significantly impacts antenna performance, with variations in permittivity potentially causing substantial tuning issues, particularly in narrowband antennas. For applications above 5GHz or for routing RF signals within the PCB, a low-loss laminate is indispensable. It’s essential to avoid changing the selected material without comprehensive testing.

2. Customization Over Copy-Pasting

Unlike off-the-shelf chip antennas, PCB antennas must be tailored to each specific device due to differences in electronics or mechanics. Each PCB antenna design should be a unique solution, even if inspired by previous designs. This customization is necessary to ensure optimal performance for complex IoT devices.

3. Embracing 2D Limitations

PCB antennas, often referred to as microstrip antennas, are two-dimensional structures integrated into the main PCB, sharing the same plane as the ground layer. This limitation constrains the available volume for the antenna design. When surface area is restricted, PCB antennas may exhibit reduced performance compared to other types like LDS, FPC, or stamped metal antennas.

4. Importance of Matching Components

Matching a PCB antenna to 50 ohms solely with an antenna radiator may not be efficient. Antenna matching components are crucial for compensating uncertainties in PCB materials and mechanical design. Without these components, iterations and prototypes can become costly and time-consuming. Adjusting matching components offers flexibility and fine-tuning for each unit, minimizing the need for additional prototypes.

Why Choose PCB Antennas?

PCB antennas can achieve comparable performance to surface-mounted chip antennas while reducing component costs. However, realizing these benefits requires careful attention to material and supplier selection throughout the product’s lifecycle. PCB antenna design is best handled by those with experience.
