MA250.A.LBI.001 RF/IF and RFID

RF antennas play an integral role in the field of telecommunications. The MA250.A.LBI.001 antenna is an omnidirectional Inverted-F antenna that is typically used in the 900MHz ISM band. This type of antenna is ideal for a variety of applications, such as point-to-point (P2P) data transmissions, cellular base stations, and Wireless Local Area (WLANs). This paper will discuss the application field and working principle of the MA250.A.LBI.001 antenna.

Application Field

The MA250.A.LBI.001 antenna is designed to operate in the 900MHz ISM band, which is used for a range of wireless communication applications. It is particularly suitable for short-range, low-rate data transmissions in both urban and rural environments, as the antenna has a wide directivity angle of 360° and excellent gain characteristics. This makes the antenna well-suited for a variety of wireless applications, such as P2P data transmissions, cellular base station services, and WLANs.

The MA250.A.LBI.001 antenna is also well-suited for telemetry applications, where low power and robust data link is required. This antenna is ideal for this type of application due to its low power consumption, and its ability to maintain reliable communication in an environment where there is significant interference or multipath distortion. The antenna is also able to provide reliable reception of low-power signals at a distance of up to 600 m in free space, making it well-suited for an array of wireless applications.

Working Principle

The MA250.A.LBI.001 antenna is an inverted-F antenna, which means that the antenna elements are “folded” onto each other in order to miniaturize the antenna without sacrificing any of its gain and directivity characteristics. In addition to this, the antenna also features a built-in balun, which helps to reduce the amount of impedance mismatch, and to ensure uniform reception across the entire frequency range.

The antenna is fed with a 50-ohm coaxial cable, and the folded antenna elements are connected to the balun at their base. These antenna elements are driven in a parallel manner, and the resulting radiation pattern is a circular pattern with no discernible side lobes. This makes the MA250.A.LBI.001 antenna ideal for applications where the antenna needs to be mounted in an enclosed space, as it will not interfere with other components in the vicinity.

The antenna also features a two-stage matching network to ensure optimal impedance matching. This matching network helps to reduce the amount of return loss and ensure that the antenna performs well even in the presence of impedance mismatches. Because of the two-stage matching network, the antenna is able to cover the entirety of the 900MHz ISM band (from 890MHz to 960MHz).

In summary, the MA250.A.LBI.001 antenna is an omnidirectional antenna that is ideal for a variety of wireless applications. Its 360° directivity angle and the two-stage matching network ensure that it is able to provide consistent performance even in the presence of impedance mismatches and interference. The antenna has a wide operating frequency range of 890MHz to 960MHz, making it suitable for a range of wireless applications in the 900MHz ISM band.
