RF Antennas: AA.108.301F21 application field and working principle

AA.108.301F21 is an antenna designed to receive and transmit signals in the radio frequency (RF) range of 315MHz to 345MHz, which quite often falls within the ISM(Industrial Scientific Medical) band. It’s a well-engineered and carefully constructed circularly polarized antenna, whose application field is quite wide.

AA.108.301F21 is mainly used in commercial systems that require high efficiency, long range and outstanding reliability, such as point-to-point systems and vehicle tracking systems. Especially in the field of vehicle tracking, as an internet of things (IOT) device, this antenna has demonstrated remarkable performance in data transmission. Besides, the typical application of the antennas includes remote control/alarming systems, remote safety, collision avoidance systems and garage door systems. Last but not least, AA.108.301F21 is a great product option for large-scale projects, due to its stability, dimensional accuracy and good quality.

The structure of the antenna is an epicircular discone with freely standing disc elements, which is why it’s called a ‘vertically polarized discone’. This design of antenna makes use of a flat disk, mounted on a thin steel wire in an inverted conical shape. The radius of the disk equals the radial distance of the cone, while the hole at the top of the cone is capped with a conducting disk. This feature creates a high impedence antenna system. The circularly polarised antenna transmits and receives signals in just one direction, minimizing distortion. The omnidirectional radiation pattern with an irradiation angle of 90˚ enables this type of antenna to receive signals at a very high-angle of elevation for maximum coverage.

The AA.108.301F21 model of antenna is open for customization of the frequency range. This feature enables it to operate across a wide frequency spectrum, making it both an efficient and a cost-effective product. Moreover, the excellent performance and durability of the antenna is backed by a warranty of 15 years.

AA.108.301F21 antenna is a highly effective RF antenna that has been designed to offer superior performance with high efficiency and long range. The powerful design, impressive features and excellent durability make this antenna a great choice for commercial applications.
