Isotropic antenna is a hypothetical radiator with a spherical radiation pattern, and 100 percent efficiency; that is, it does not have losses, so all the power fed to it is The chapter also considers concepts of aperture. 6 Mutual Coupling Effects 279 9. Antenna Theory - Lonosphere and its Layers. Multiple Input Multiple Output (MIMO) - In wireless communications, when multiple antennas are used both at the transmitting end as well as the receiving end, the configuration is said to be multiple input, multiple output or MIMO. The shape of this array symbolizes the turnstile, which is used at the entrances of few places. Understanding these concepts is very important for performing tasks related to antenna design, operation, and maintenance in See more Antenna Theory Tutorial in PDF - You can download the PDF of this wonderful tutorial by paying a nominal price of $9. • Typically an antenna consists of an arrangement of Figure 2: Propagation of electromagnetic wave within free space. These are well known and widely used antennas. Slot Antenna is an example of Aperture antenna. Construction of Yagi-Uda Antenna. com .
