Introduction

The SQ2449PV36RSM is a special type of RF antenna that is designed for multi-band applications. This antenna is a rectangular microstrip patch antenna with a rotationally symmetric pattern which provides excellent performance over a wider frequency range. It is used in a variety of applications, including base station antenna systems, mobile handheld devices, and computer networks.

Application Field

The SQ2449PV36RSM is an ideal choice for applications requiring high gain and wideband performance such as wireless local area networks (WLANs), smart antennas, and mobile communications. It is designed to operate within the 2.4-2.5 GHz range and provides a gain of 24 dBi. Its relatively small form factor is suitable for integration into tight spaces, making it ideal for use in mobile handhelds and other portable devices. The antenna offers a low-VSWR over a wide frequency range and features low return loss, giving it superior performance in both indoor and outdoor environments.

Working Principle

The SQ2449PV36RSM utilizes a rectangular patch structure and radiates in a rotationally symmetric pattern that is tailored for multi-band applications. This antenna is a microstrip antenna that works by exciting a thin flat plate or "patch" that is printed on dielectric material and has a low magnetic and dielectric loss. The patch has two distinct resonance frequencies and a strongly directive gain pattern, meaning it is capable of narrow beamwidths and excellent efficiency.The antenna uses a combination of multiple frequency selective surfaces (FSS) to tune the antenna for multiple operating bands, and its geometry is optimized for maximum gain. Additionally, the antenna utilizes an internal balun to ensure balanced operation, eliminating the need for external components.

Conclusion

The SQ2449PV36RSM is a high-performance RF antenna that is designed for use in multi-band applications. This antenna boasts a high gain of 24 dBi and a wide frequency range, making it suitable for use in WLANs, smart antennas, and mobile communications. It works by exciting a rectangular patch antenna printed on dielectric material and features multiple FSSs for tuning various operating bands. Additionally, its small form factor and internal balun are suitable for integration into mobile handhelds or other tightly-packed devices.
