ANT-GPS-SH-SMA

RF antennas have become ubiquitous in today\'s wireless systems, and their use is ubiquitous for myriad commercial and government applications. This article will focus on three specific types of RF antennas: ANT-GPS-SH-SMA, and their application field and working principle.

ANT-GPS-SH-SMA

The ANT-GPS-SH-SMA antenna is an omnidirectional antenna, designed for portable installations. It offers outstanding performance in small size, providing high gain and excellent directivity over a wide frequency range. This antenna is widely used for GPS, Wi-Fi, cellular networks, wireless microphones, and digital television. The antenna is made up of multiple antennas and a helical antenna shim to provide maximum gain while reducing error caused by wind and environment. The gain of the antenna is typically 3dB, and the VSWR is less than 1.5. The frequency range of the antenna is from 690 MHz to 2.4 GHz.

Application Field

ANT-GPS-SH-SMA antennas are commonly used for GPS receivers, Wi-Fi adapters, cellular networks, wireless microphones, and digital television. The antenna can also be used in many other applications such as Machine-to-Machine (M2M) communication, wireless repeaters, point-to-point wireless bridges, and other remote data exchange applications.

Working Principle

The working principle of the ANT-GPS-SH-SMA antenna is based on the directivity of the antenna in the direction of the incoming signal. The helical antenna shim provides the antenna with omnidirectional emission by redirecting the incoming signal in the desired direction. The gain of the antenna is achieved by the antennas in the array absorbing the signal from the incoming electromagnetic waves and redirecting it in the desired direction. The antenna then transmits and receives the signal with a higher gain than if the signal was not redirected.

Conclusion

ANT-GPS-SH-SMA antennas are widely used in various applications due to their small size, high gain, wide frequency range, and directivity. They are used in many applications including GPS receivers, Wi-Fi adapters, cellular networks, digital television, wireless microphones, and M2M communication. The working principle of the antenna is based on the directivity of the antenna in the direction of the incoming electromagnetic signal.
