Antenna gain is a measure of an antenna's ability to concentrate input power for radiation. Its size has a significant impact on signal transmission in terms of transmission distance, signal strength, and interference resistance.

Vertical polarization: For example, Kinghelm's Bluetooth PCB antenna typically adopts a vertical polarization method to ensure its coverage range in the horizontal plane.

Operating Frequency: The center frequency or frequency range for which the antenna is designed to operate, determining the types of signals the antenna can effectively transmit or receive. For example, the operating frequency of a GSM900 system antenna is around 900MHz.

When the gain is the same, the polarization of the antenna mainly influences signal transmission in aspects such as signal propagation direction, anti-interference capability, penetration ability, and multipath effects, as described below:

The price of Kinghelm’s internal antennas can vary significantly depending on several factors, including the specific model, the required performance characteristics, and the complexity of the manufacturing process. Since each product is tailored to meet the needs of different applications, the final cost will be influ……
