This antenna has a high attenuation of the back radiation and high gain in front radiation, as a result high front to back ratio (FB ratio) can be achieved in this antenna.
Radiation characteristics such as antenna gain, side lobe level, and back radiation are thus discussed.
These FSSs are not backed by a metal reflector hence a small amount of transmission through the FSS is allowed, which also leads to a small amount of back radiation.
Greenhouse gases from the atmosphere trap the heat radiating back from the earth's surface, while aerosols in the atmosphere reflect back radiation coming from the sun which causes dimming.
This is due to impedance mismatch and pattern degradation, as the back radiation level increases rapidly at these frequencies.
Front and back radiation is essentially a modified dipole (front and side waves 180 degrees out of phase), but the sound level in front is only about a third of the level from the inside rear corner.
Power-packed Tony Dobbin had the Toon army in full cry as he drove This Is Serious to peg back Radiation on the run-in to land the pounds 38,000 prize.
The volcanic particles absorb and scatter back radiation from the sun.
The use of DGS offers back radiation which is not desirable for antenna design as the DGS is supposed to perturb and suppress the occurrence of any orthogonal resonance.
Low back radiation and low cross-polarization are also obtained at the two principal planes.
