Plot the radiation pattern of loop antenna with the circumference approximately equals to ?, operating at 1 GHz frequency.

Expert Solution

Radiation Pattern : Practical antennas do not radiate uniformly in all directions. The radiation pattern is a graphical representation of the distribution of radiation energy as a function of angle about the antenna in the three-dimensional space and is generally measured in the far field region.

The frequency range of operation of loop antenna is around 300MHz to 3GHz. This antenna works in UHF range.

A loop antenna is a coil carrying radio frequency current. It may be in any shape such as circular, rectangular, triangular, square or hexagonal according to the designer’s convenience.

Loop antennas are of two types.

Large loop antennas
Small loop antennas
Large loop antennas are also called as resonant antennas. They have high radiation efficiency. These antennas have length nearly equal to the intended wavelength.

L=?L=?

Small loop antennas

Small loop antennas are also called as magnetic loop antennas. These are less resonant. These are mostly used as receivers.

These antennas are of the size of one-tenth of the wavelength.

L=?10
