Radiation pattern is just a map of how the strength of the signal varies around (transmitting) antennas. For some, like a simple whip antenna, the patttern too is quite simple. For directional antennas they can be quite complicated.
A passive antenna is an antenna that is not powered by an amplifier.
end-fire antenna = surface-wave antenna
A thin antenna has nothing to do with the physical size of the antenna. Any antenna whose length is less than (1/10) of the wavelength of the signal is thin antenna. A linear antenna is one in which the current distribution is linear or bears a linear relationship with some parameter, say voltage of the antenna...... Mukesh

The power radiation pattern represents how the radiated power from an antenna is distributed in space. It shows the strength of the radiated power in different directions relative to the antenna. This pattern helps to understand how an antenna radiates energy and is important in designing and evaluating antenna performance.
A smart antenna is used to identify signal signature and to track an antenna beam on the target. Some are for beamforming which is used to create the radiation pattern of the antenna.
Antenna gain of base station for a specific user depends on antenna pattern, antenna orientation (azimuth and tilt) and user's coordinates with respect to base station.

The antenna is located inside the rear window. You will notice the pattern in the glass (similar to the defroster pattern).
The horizontal plane pattern of an antenna describes its radiation characteristics when viewed from above, displaying how the antenna radiates signal in the horizontal plane around it. In contrast, the vertical plane pattern depicts the antenna's radiation characteristics when viewed from the side, showing how it radiates signal up and down. These patterns are crucial for understanding an antenna's coverage and performance in different environments, influencing its application in communication systems.
The isotropicantenna by definition has a radiation pattern that is a perfect sphere. The omni driectional antenna is characterized by a radiation pattern resembling a doughnut.
Radiation pattern is just a map of how the strength of the signal varies around (transmitting) antennas. For some, like a simple whip antenna, the patttern too is quite simple. For directional antennas they can be quite complicated.
The tip of an antenna is commonly referred to as the "radiating element" or "antenna tip." This part is crucial for the emission and reception of electromagnetic waves. In certain types of antennas, such as dipoles, the tips are where the current is most concentrated, playing a significant role in determining the antenna's radiation pattern and efficiency.
The flow chart follows this pattern; Transceiver to amplifier then out to swr meter, then into antenna tuner then out to antenna.
it is the integral of the normalised power pattern over sphere (4pie.st)
An asymmetrical polar diagram is a graphical representation of an antenna's radiation pattern that shows variations in signal strength with direction. It can be used to analyze the directionality and coverage of an antenna.
