ANT-868-PW-QW

RF antennas have been around since the first radio broadcasts, and they have become a vital component in wireless communication. The ANT-868-PW-QW antenna is an example of a specialized RF antenna that is designed for use with 868MHz ISM Band (Industrial, Scientific and Medical) applications. This article will discuss the application field and working principle of the ANT-868-PW-QW antenna.

The ANT-868-PW-QW is an RF antenna designed to operate in the 868MHz ISM band, a frequency channel most commonly employed in short-range wireless products such as alarm systems, short-range data links, and home automation devices. It is an integrated package of two elements, the antenna and the accompanying radio circuit, which ensures optimum performance. The antenna is optimized for linear polarization, and generally, the circular polarization is not compatible with the ANT-868-PW-QW.

Antenna Application Field

The ANT-868-PW-QW is suitable for use in applications such as short-range security, home automation, medical instrumentation, and wireless data links. It is often used in combination with radio transceivers and transmit/receive modules (RT-T/R) to provide a robust and reliable solution for short-range communication needs. The antenna can be connected to single- and multi-wire systems and supports a wide variety of antenna designs, such as dipole, patch, helical, end-fired and ridged-line antennas.

Antenna Working Principle

The working principle of the ANT-868-PW-QW is simple and straightforward; it receives and transmits radio waves using transmitting and receiving elements. The elements used are typically made of an insulated conductor, such as metal or plastic-coated copper. The antenna is usually a dipole or patch array, with a radiation pattern concentrated in the direction of the radio wave. When a radio wave is received by the antenna, it is converted into electrical current, and then it is conducted to the receiver. Likewise, when a signal is being transmitted, the electrical current is applied to the antenna and an electromagnetic wave is produced.

Performance Specifics

The performance specifics of the ANT-868-PW-QW are favorable. It is rated for a gain of up to 6.0dBi, and has a VSWR of less than 1.6:1. It is omnidirectional, with a pattern optimized for the horizontal plane. The antenna has a peak efficiency greater than 75%, and a low noise figure of -58 dB. The mount type is either vertical or horizontal, and the antenna requires a power level of 80 mW (0 dBm) for optimum performance. The antenna is also designed to withstand a wide range of temperature and humidity conditions.

The ANT-868-PW-QW antenna is a great choice for wireless communication systems that require a reliable, low-power solution. It is designed to be compatible with a variety of radio transceivers and transmitter/receiver modules, making it ideal for a wide range of applications. With its high gain, low VSWR, and excellent performance in various temperature and humidity conditions, the ANT-868-PW-QW makes it easy to achieve reliable short-range wireless communication.
