RF communication antennas act as the “signal gateway” of wireless systems, widely used in mobile phones, base stations, satellites, IoT devices, and more. Compared to ordinary low-frequency antennas, RF communication antennas (operating typically between 300kHz and 300GHz) have unique differences in structural design, ……

Communication antennas act as the “bridge” of wireless communication. Different scenarios require varying coverage ranges, transmission distances, and anti-interference capabilities, which has led to the development of multiple types of communication antennas. This article systematically reviews antenna classifications……

​In wireless communication system design, accurately calculating the transmission distance of communication antennas is a critical step to ensure stable signal ……

The performance of a communication antenna depends not only on its design, but also heavily on precise manufacturing processes. From the fabrication of metal radiators to final performance testing, every step of process control directly impacts key indicators such as gain, VSWR, and weather resistance. This article bre……

By radiation pattern Omnidirectional antennas: Radiate horizontally in 360°, gain of about 3–8 dBi; suitable for multi-directional coverage. Directional antennas: Focus the signal within a beam width of about 30°–120°, gain ranges from 8–40 dBi; ideal for long-distance point-to-point communication.

As a core wireless component in compact electronic devices—such as smartwatches, Bluetooth earphones, and IoT sensors—Bluetooth patch antennas are widely used for their small size (typically 5–20 mm) and high level of integration. However, during installation and debugging, many engineers wonder: Does a Bluetooth patch……

​The directional characteristics of Bluetooth patch antennas directly determine a device’s signal coverage range and transmission stability. In compact devices ……
