Hi there! I'm Andrew Chen, the founder of sannytelecom.com. I've been operating a factory in China, designing and producing various kinds of communication antenna products since 2015. I'm passionate about wireless antennas and sustainability. In the articles, I want to share with you my knowledge about antennas & related products from a Chinese supplier's perspective.
Millimeter waves (mmWave) refer to a portion of the electromagnetic spectrum with wavelengths ranging from 1 to 10 millimeters. This frequency range falls between microwave and infrared waves.
When choosing a horn antenna, you need to focus on a couple of parameters based on your application. It’s included but not limited to frequency ranges, gain, polarization as well as the half-power beamwidth, etc.
Horn antennas are of different types that give you a variety to choose from. The choice would depend on the need and function that the antenna has to perform. Following are 9 main types of horn antennas that will help you understand their different features and determine which one you need.
A high gain directional antenna which is typically used to receive or transmit signals in the wireless backhaul networks at 4.9-6.4GHz, is a WiFi Parabolic Dish Antenna.
For WiFi parabolic dish antenna, the gain ranges from 18dBi to 40dBi between 2.4GHz and 6.5GHz, depending on the exact frequency range and reflector diameter.
All RFID systems need antennas to transmit and receive signals. But not all antennas are created equal. There are a variety of factors you need to consider when choosing the right UHF RFID antenna for your application.
