RF Antennas

EXB148SM application field and working principle

The EXB148SM is an omnidirectional RF antenna suitable for a wide range of applications. Typically used in computer networks, wireless microwave communication, and surveillance systems, it is designed for operation in the 824-960 MHz frequency band with a peak gain of 10-12 dBi. The antenna has a unique design featuring a stabilized linear polarization beam, which makes it a viable choice for applications requiring an omnidirectional pattern with low cross-polarization discrimination and good overall gain.

The EXB148SM is powered by an active microstrip radiating element. The active element is connected to the antenna body via a balun, with the entire assembly enclosed in a radome. The active element is designed to provide a continuous sinusoidal harmonic radiation pattern, with the signal varying in amplitude across the frequency range. This results in a stable axial ratio and low cross-polarization discrimination over the entire frequency band. In addition, the antenna is designed to minimize backward radiation and is moisture and weather resistant.

The antenna is highly efficient and has high average gain (>10-12 dB) over the entire frequency band. It can be used with a wide range of RF systems, including but not limited to point-to-point broadband systems, public safety systems, point-to-multipoint systems, and distributed antenna systems. It is also suitable for use with many applications, such as cell phone systems, private radio networks, and GPS systems.

The EXB148SM is easy to install and maintain, thanks to its robust construction and design. It is also easy to integrate into existing systems due to its plug-and-play setup. However, it is important to keep in mind that the antenna is designed for use in specific frequencies, so the signal needs to be kept within the designated operating range to ensure maximum effectiveness.

In summary, the EXB148SM is an omnidirectional RF antenna designed to meet the specific needs of various applications. It is a simple yet reliable solution with a unique design, which provides users with a stabilized linear polarization beam. The antenna’s peak gain and average gain are high over the entire frequency band, and it is robust and easy to install and maintain. Furthermore, it is suitable for use with many applications, including but not limited to point-to-point broadband, public safety, and GPS systems.
