Loop Antenna Radiation Pattern

Loop Antenna Radiation Pattern - As the frequency progresses to the second and third resonances the perpendicular radiation fades and strong lobes near the plane of the loop arise. Web a radiation pattern defines the variation of the power radiated by an antenna as a function of the direction away from the antenna. Web let’s start with a simple square loop in free space, fed in the middle of one side, and see how the radiation pattern and other characteristics vary as we change the frequency (or change the length in wavelengths, which is the same thing). These antennas have low radiation resistance and high inductive reactance, so that their impedance is difficult to match to a radio impedance (often 50 ohms). The tangent line at 0° indicates vertical polarization, whereas the line with 90° indicates horizontal polarization. Web azimuth radiation pattern of a horizontally polarized full wave loop antenna in free space. Here, c denotes the loop’s circumference. This power variation as a function of the arrival angle is observed in the antenna's far field. The pattern is similar to a dipole, but about 6 degrees wider however, the vertical pattern is more compressed, providing about 1 db of gain. Courtesy himanshu rohilla, 3rd year ee, iit delhi.

Web an antenna is a device that couples currents to electromagnetic waves for purposes of radiation or reception. Web a radiation pattern defines the variation of the power radiated by an antenna as a function of the direction away from the antenna. As the frequency progresses to the second and third resonances the perpendicular radiation fades and strong lobes near the plane of the loop arise. The radiation patterns for different angles of looping are also illustrated clearly in the figure. These antennas have low radiation resistance and high inductive reactance, so that their impedance is difficult to match to a radio impedance (often 50 ohms). This still qualifies as a “small loop”, but is beginning to show some of the characteristics of a larger loop. Web let’s start with a simple square loop in free space, fed in the middle of one side, and see how the radiation pattern and other characteristics vary as we change the frequency (or change the length in wavelengths, which is the same thing). Radius of loop= 5.3 mm, circumference = λ. This power variation as a function of the arrival angle is observed in the antenna's far field. The pattern is similar to a dipole, but about 6 degrees wider however, the vertical pattern is more compressed, providing about 1 db of gain.
