Dipole Antenna directivity as a function of dipole length. Figure 6 indicates that up until approximately L =1.25 the directivity increases with length. However, for longer lengths the directivity has an upward trend but is no longer monotonic.
Friis Transmission Formula is the most fundamental equation of antenna theory. This equation relates transmit power, antenna gains, distance and wavelength to received power. This page is a must-read for those interested in antenna theory. Antenna Temperature. Antenna Temperature is a property of an antenna and the environment it operates in.
Chapter 2: Antenna System-Level Performance Parameters. Before the theoretical treat-ment of antennas starts, it is good to have a knowledge of what parameters are important to characterize an antenna and what these parameters mean. This chapter treats this topic
The book provides a broad coverage of antenna types and phenomena, for operations at very low radio frequencies, as well as frequencies up to those of submillimeter wavelengths. Unlike most university-level antenna textbooks, it does not require prior skills in electromagnetic theory, sophisticated mathematics, or computer programming.
1. Definition of the Antenna and Wave-Motion The radio antenna may be defined as the interface between a circuit in which electrical power is constrained to follow conducting paths, and electromagnetic radiation travelling freely through space. The antenna may convert power in the circuit into radiated energy or vice versa, forming either
These lecture notes are heavily based on the book of Antenna Theory and Design by W.L. Stutzman and G. A. Thilie. For future version or any proposals, please contact with Dr. Serkan Aksoy (saksoy@gtu.edu.tr).
