Isotropic Antennas

Isotropic antennas are theoretical antennas that radiate signals equally in all directions, like a perfect sphere. They serve as a baseline to compare the performance of real antennas. In practice, no antenna is truly isotropic, but this concept helps engineers understand how well an antenna can distribute its signal in space. By using isotropic antennas as a reference, we can evaluate the gain and efficiency of other antennas, which might focus signals in specific directions, thus enhancing communication effectiveness in certain applications.
