Loop Antenna Radiation Pattern

Loop Antenna Radiation Pattern - The tangent line at 0° indicates vertical polarization, whereas the line with 90° indicates horizontal polarization. Here, c denotes the loop’s circumference. Courtesy himanshu rohilla, 3rd year ee, iit delhi. 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). 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 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). Web the antenna feed points would be in series with the loop, such that a small loop looks somewhat like a short circuit across the antenna feed. Web loop antennas are usually classified as electrically small ( c < λ / 3 ) and electrically large (c ∼ λ ). The radiated power is now maximum along the axis of the loop, not in the plane of the loop. Web a radiation pattern defines the variation of the power radiated by an antenna as a function of the direction away from the antenna.

Radius of loop= 5.3 mm, circumference = λ. 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). Here, c denotes the loop’s circumference. Courtesy himanshu rohilla, 3rd year ee, iit delhi. Web the antenna feed points would be in series with the loop, such that a small loop looks somewhat like a short circuit across the antenna feed. 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. 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 azimuth radiation pattern of a horizontally polarized full wave loop antenna in free space. This still qualifies as a “small loop”, but is beginning to show some of the characteristics of a larger loop. The radiated power is now maximum along the axis of the loop, not in the plane of the loop.
