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.

In the modern landscape of RF communication and high-frequency signal transmission, connector stability, precision, and compatibility are critical to system performance. The Kinghelm KH-SMA-KEB16.5-P1.3 SMA PCB connector, a high-quality semi-threaded straight SMA female connector with offset pins, addresses these needs……
