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.

What is an antenna?
In Electomagnetics, Radio, Electronics, etc.:An antenna is a structure that couples energy between a circuit (radio, cell phone, etc.) and free space. The plural is antennas.In Biology, Zoology, etc.:An antenna is an organ used to sense the surroundings. The plural is antennae.
What is passive antenna?
A passive antenna is an antenna that is not powered by an amplifier.
End fire antenna?
end-fire antenna = surface-wave antenna
What is Polar Radiation?
This will be a map of the radiation pattern of an antenna.
What is the Radiation pattern of loop antenna?
cardioids
How does a smart antenna work?
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.
Difference between isotropic antenna and omnidirectional antenna?
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.
Advantages of omni directional antenna?
can transmit in all directions with a donut shaped radiation pattern.
What is radiation pattern of isotropic antenna?
By definition, an isotropic radiator radiates equally well in all directions. A simple vertical whip would have such a pattern in the horizontal field.
What can transformation can occur in a radio antenna?
The radio antenna converts electromagnetic radiation to electrical energy
Radiation resistance of quarter wave monopole antenna is?
The radiation resistance of quarter wave monopole is 36.5 ohms
What is the value of radiation resistance of half wavelength dipole antenna?
36 ohm
How do you block antenna radiation?
Radiation from an antenna can be blocked by using a simple sheet of conducting material. Aluminum foil would work. But you'd have to set things up so whatever it is you are shielding is completely in the electromagnetic shadow of the antenna. Metal screen would work, too, but you'd have to make some calculations as regards the frequency of the radiation you wish to block and the size of the openings in the screen. You can see the items in your microwave heating up, but the radiation can't get out. Same principle.
What is antenna tilt?
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.
