Why is the efficiency of a corrugated horn antenna higher than the convention horn antenna

The efficiency of a corrugated horn antenna is higher than that of a conventional horn due to its reduced back reflection, achieving levels of -20 dB compared to -10 dB in conventional designs. This allows for up to 99% of input power to be effectively radiated, enhancing performance in applications like satellite communications and radar

What is the difference between a load bank and a dummy load

A load bank simulates real-world conditions by applying controlled loads to power systems, typically ranging from 100 kW to 2 MW, allowing detailed performance testing. In contrast, a dummy load absorbs power without measurement capabilities, usually rated at 50 to 1,000 watts, used primarily for RF applications. Load banks provide critical data, while dummy loads

What is an RF termination

An RF termination is a passive component designed to absorb excess signal power in RF systems, typically with an impedance of 50 ohms. For example, a 100-watt RF termination can manage signals up to 18 GHz while maintaining a return loss greater than 20 dB, ensuring only 1% of the signal reflects back for optimal

How do RF rotary joints work

RF rotary joints enable signal transfer between stationary and rotating parts, typically handling frequencies from 1 GHz to 40 GHz with insertion loss under 0.5 dB. They ensure efficient communication in systems like radar and satellite, often supporting power up to 5 kW at lower frequencies. Transmission Path At the Ku-band, 12-18 GHz; an RF

Which type of antenna is typically used for long distance communication

Parabolic dish antennas are ideal for long-distance communication, providing a gain of up to 47 dBi. For example, a 2.4-meter dish operates efficiently at 12 GHz, enabling satellite communication over 35,786 kilometers with power outputs of 1 to 10 kilowatts. Parabolic (Dish) Antennas Parabolic or Dish Antennas in Satellite Communications The parabolic dish antennas play
