antenna effect

[an′ten·ə i′fekt]
(electromagnetism)
A distortion of the directional properties of a loop antenna caused by an input to the direction-finding receiver which is generated between the loop and ground, in contrast to that which is generated between the two terminals of the loop. Also known as electrostatic error; vertical component effect.

The research team says the new cell can increase the plasmonic antenna effect, which improves the cells light absorption ability and, as a result, its conversion efficiency.
It should be noted that the same antenna effect should also be considered in the modal method as discussed in Section 1, since antennas are usually involved in the radiating of RF signals.
Copper cabling creates more of an antenna effect than thinner, mylar alminium foil cables, long lengths of aluminium cable won't pick up interference.
The use of the bowtie geometry has two significant benefits over previous work on plasmon lasers: (1) the bowtie structure provides a well-defined, electromagnetic hot spot in a nano-sized volume because of an antenna effect, and (2) the individual structure has only minimal metal "losses" because of its discrete geometry.
The manufacturer of thermally conductive plastics and heat transfer solutions also noted that its proprietary CoolPoly grades have no antenna effect (there is no amplification of electromagnetic or radio frequency interference and no magnetic coupling) and repel both heat and aluminum.
This eliminates the antenna effect of the lead, which causes the many problems of MRI and pacemaker incompatibility.
The superscript H is the Hermitian operator, and h is the M x 1 composite fading channel vector including the overall antenna effect.
Features include no antenna effect (no amplification of electromagnetic or radio frequency interference and no magnetic coupling), 50 percent lighter weight than aluminum, and they provide part design flexibility.
In order to examine the noise in received signals due to the jitter and antenna effects, we analyze the standard deviation of the measured data.
This means that the antenna effects, in addition to spatial domain propagation, need to be taken into account in the testing.
We are confident that multi-antenna OTA testing will enable us to further improve the quality and performance of our mobile phones as the testing now includes the antenna effects which are crucial in multi-antenna systems.
The simulation can be for an ideal environment or for one with impairments, such as multi-path, pseudo-range error, loss of satellite visibility, satellite power change, ionosphere and tropospheric atmospheric attenuation, antenna effects, CW interference, or AWGN.
