What is a waveguide circulator in a microwave
A waveguide circulator directs microwave signals between three ports, isolating signals efficiently. For example, at 10 GHz, it handles 1 kW transmitted power with less
Why do satellites use high frequency
Increased Data Transmission Capacity The Ka-band, operating between 26.5 GHz and 40 GHz, supports data rates of over 100 Mbps, allowing a single satellite to
How to design an antenna for a specific frequency
To design an antenna for a specific frequency, first calculate the wavelength using λ=cf\lambda = \frac{c}{f}λ=fc, where ccc is the speed of light and fff
What is the difference between Yagi and Omni antenna
Yagi antennas are directional, offering higher gain (up to 12 dB) and long-range communication, typically up to 50 kilometers at 2.4 GHz. In contrast, Omni
What is the material of a directional coupler
A directional coupler uses materials like copper (conductivity ~5.96×10⁷ S/m), dielectric substrates like FR4 (dielectric constant ~4.5), or PTFE for high frequencies (loss tangent <0.001),
What is the function of coupler antenna
A coupler antenna splits or combines signals, matches impedance, filters frequencies, and measures signal power. For example, in a 1,000-watt system, it diverts 10 watts
What are the different types of cable ends
There are several types of cable ends, including N-Type, BNC, SMA, F-Type, and TNC connectors. For example, the N-Type connector handles frequencies up to 11
What is the limit of C-Band

How do satellite antennas work
Satellite antennas focus signals using parabolic dishes, amplifying them with gains up to 55 dB for high frequencies like Ka-band (26.5-40 GHz). Proper alignment within
How do you test a directional coupler
To test a directional coupler, apply a 0 dBm signal and measure key parameters. For instance, verify coupling factor (-20 dBm for 20 dB coupling),
What are the factors contributing to the loss inside a wr187 waveguide
Losses in a WR187 waveguide stem from conductor losses (~0.02 dB/m at 5 GHz), surface roughness (>1 µm increases resistance), leakage (~0.1 dB from misaligned
What is the beamwidth of quad-ridged horn antenna
The beamwidth of a quad-ridged horn antenna varies with frequency. At 1 GHz, it’s typically around 60°, narrowing to 15° at 18 GHz. Measure it
What are the 7 radio waves
The seven types of electromagnetic waves are radio (1mm-100km wavelengths), microwaves (1mm-1m), infrared (700nm-1mm), visible light (400-700nm), ultraviolet (10-400nm), X-rays (0.01-10nm), and gamma rays (<0.01nm).
What messes with radio waves
Physical obstructions, weather, and atmospheric layers disrupt radio waves significantly. For example, heavy rain can reduce signal strength by 20 dB per kilometer at 12
