​The main use of power supply connection cables is to establish a connection between electrical equipment and the power source, enabling the transmission and di……

Motherboard power cables: These cables are used to power the computer motherboard, typically available in 24-pin and 20-pin configurations, providing stable power for various chips, interfaces, etc., on the motherboard.

Type of Ceramic Material: Different types of ceramic materials have varying properties and prices. For instance, ceramic antennas made from high dielectric constant materials offer better signal transmission and radiation performance, which makes them more expensive. On the other hand, antennas made from standard ceram……

Influenced by Raw Material Prices: If the prices of raw materials, such as metals, rise, the production costs of board-end antenna sockets will increase, which could lead to a price increase. Conversely, if raw material prices fall, prices may decrease to some extent under market competition.

Horizontal Polarization: The direction of the electric field intensity is parallel to the ground, and the electric field vector oscillates in the horizontal direction.

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……
