What is the difference between horn antenna and dipole antenna

Differences between horn antenna and dipole antenna: 1. Structure: horn antenna is a waveguide opening structure (gain 10-25dBi), dipole is a λ/2 metal rod (gain 2-3dBi); 2. Directivity: horn antenna directional radiation (main lobe width <60°), dipole omnidirectional radiation; 3. Frequency: horn is suitable for 3-300GHz microwave, dipole is suitable for 30MHz-3GHz; 4. Application: horn […]

What is the difference between horn antenna and parabolic dish antenna

Horn antennas offer moderate gain (10-20 dB), wide bandwidth, and simpler design, whereas parabolic dish antennas provide higher gain (30-40 dB) and directivity but require precise alignment. Introduction to Antenna Types Basic Principles of Antennas Antennas are crucial components in wireless communication, converting electrical power into radio waves and vice versa. A key parameter, the

Double Ridged Waveguides

What is Double Ridged Waveguides

Understanding Double Ridged Waveguides Double ridged waveguides are an important development in the field of waveguide design as they provide superior characteristics to both their single-ridged and standard counterparts. This can be seen clearly when comparing their fundamental characteristics, the behavior of transverse electric modes and the critical role of ridge dimensions in wave propagation.

SATCOM ANTENNA

What is SATCOM ANTENNA

Satellite communication antennas are high-precision devices used to send and receive geosynchronous orbit satellite signals. The gain of a typical Ka-band parabolic antenna can reach 45dBi. It uses a carbon fiber sandwich structure to achieve ±0.1mm deformation control, and completes polarization calibration (error <0.5°) and Doppler frequency offset compensation (accuracy ±10Hz) through a precision servo
