An antenna is a device that converts electrical signals into electromagnetic waves and vice versa. Antennas are used in a wide range of applications, including communication systems, radar systems, and navigation systems. Wave propagation, on the other hand, refers to the way electromagnetic waves travel through a medium, such as air, water, or space.
A single antenna often isn't enough for long-range communication. K.D. Prasad explains how combining multiple antennas (arrays) can shape the signal.
fc=9Nmaxf sub c equals 9 the square root of cap N sub m a x end-sub end-root (Where Nmaxcap N sub m a x end-sub is the maximum electron density per cubic meter)
Directivity measures the concentration of radiation in a specific direction. Gain factors in the electrical efficiency of the antenna alongside directivity.
The wave travels directly from the transmitting antenna to the receiving antenna. Since it cannot bend around the Earth, it is limited by the curvature of the Earth.
Very High Frequency (VHF), Ultra High Frequency (UHF), and microwave frequencies (30 MHz and above).

Antenna arrays are used to improve the performance of antennas. There are several types of antenna arrays, including:
An antenna is a transitional structure between free space and a guiding device (like a waveguide or transmission line). It acts as an impedance-matching device that converts guided electromagnetic waves into free-space waves, and vice versa. Fundamental Parameters of Antennas
