Parallel Plane Waveguide: Parallel Plane Waveguide - As we know already in connection with transmission lines, that reflections and standing waves are produced if a line is terminated in a…
Reflection of Electromagnetic Waves by a Conducting Surface: In view of the way in which signals propagate in waveguides, it is now necessary to consider what happens to Reflection of…
Rectangular Waveguides: Rectangular Waveguides - As we know already that the term skin effect indicated that the majority of the current flow (at very high frequencies) will occur mostly along…
Radiation Pattern of Antenna: The important terms and definitions used in connection with antennas and their Radiation Pattern of Antenna are Antenna Gain and Effective Radiated Power: Certain types of…
Interference of Electromagnetic Waves: Interference of Electromagnetic Waves occurs when two waves that left one source and travelled by different paths arrive at a point. This happens very often in…
Choke Balun: A Choke Balun, or balance-to-unbalance transformer, is a circuit element used to connect a balanced line to an unbalanced line or antenna. Or, as is perhaps a little…
Fundamentals of Transmission Lines: Fundamentals of Transmission Lines (in the context of this book) are considered to be impedance-matching circuits designed to deliver power (RF) from the transmitter to the antenna,…
Transistor RF Amplifier Circuit: A radio receiver always has an RF section, which is a tunable circuit connected to the antenna terminals. It is there to select the wanted frequency…
