Waveguide horn antenna is also an aperture antenna, and its internal metal wall gradually transitions to ensure the impedance matching between the waveguide port and the free space. In this way, the aperture and axial length of the waveguide horn antenna can be adjusted to obtain the gain and ...
All physical systems are subject to some types ofextraneoussignals or noise during operation. Examples of these signals are thermal-noise voltage in electronic circuits and brush orcommutatornoise in electric motors. External disturbance, such as windgustacting on anantenna, is also quite common in ...
the point is generally not in the center of the antenna, but a tiny adjustment in the XY direction. Such impedance matching methods are simple and do not increase costs. Move only in a single -axis direction is called a single bias antenna, and the movement of both axes is called dual ...
Gain is just one of the standard parameters used to measure the performance of an antenna. In addition to gain, engineers must consider frequency,bandwidth, impedance and polarization when selecting an antenna for a particular application. The durability of an antenna and its ability to handle extr...
NFC Antenna Testing Evaluating NFC antenna designs requires specialized wireless testing: Return Loss Return loss vs. frequency characterizes antenna tuning and matching. A deep notch at 13.56 MHz indicates resonance. Impedance The complex impedance spectrum verifies inductive behavior at 13.56 MHz and res...
Both can be designed to be 50Ω, and this is not an issue.However the impedance of an antenna can vary very considerably dependent upon its characteristics and the frequency - often there are inductive and capacitive elements to the overall impedance of the antenna....
