Frequently Asked Questions

An antenna works by converting electrical currents into radio waves, which are then broadcast into the surrounding environment. A receiving antenna captures these electromagnetic waves and converts them back into electrical currents. The strength of these currents depends on the signal’s intensity, allowing for the transmission of data over distances.

Selecting the correct antenna is vital because a mismatch can lead to data throughput issues or reduced range. Antennas must resonate at specific frequencies that match the associated radio system. If the antenna is not properly matched, it can cause frequency misalignment, leading to device failures and poor performance.

When integrating an antenna, you should consider:

• Frequency Coverage: Ensuring the antenna operates within the required frequency bands.
• Location/Size: Assessing space constraints and placement within the device.
• Gain, Radiation Patterns, and VSWR: Evaluating the antenna's efficiency and performance.
• Environment: Considering the operating environment, which may impact antenna performance.

At Field Theory, we begin with thorough simulation work to predict how the antenna will perform. We then proceed with 3D printing and prototyping to refine the design.
