Antennas: From Theory to Practice by Dr. Yi Huang, Kevin Boyle

By Dr. Yi Huang, Kevin Boyle

Practical, concise and whole reference for the fundamentals of recent antenna layout

Antennas: from concept to perform discusses the fundamentals of recent antenna layout and conception. constructed in particular for engineers and architects who paintings with radio communications, radar and RF engineering, this ebook bargains useful and hands-on remedy of antenna thought and strategies, and gives its readers the abilities to examine, layout and degree numerous antennas.

Key gains:

  • Provides thorough insurance at the fundamentals of transmission traces, radio waves and propagation, and antenna research and layout
  • Discusses commercial commonplace layout software program instruments, and antenna dimension gear, amenities and strategies
  • Covers electrically small antennas, cellular antennas, UWB antennas and new fabrics for antennas
  • Also discusses reconfigurable antennas, RFID antennas, Wide-band and multi-band antennas, radar antennas, and MIMO antennas
  • Design examples of varied antennas are supplied
  • Written in a realistic and concise demeanour via authors who're specialists in antenna layout, with event from either academia and undefined

This publication should be a useful source for engineers and architects operating in RF engineering, radar and radio communications, looking a entire and functional advent to the fundamentals of antenna layout. The publication is also used as a textbook for complex scholars getting into a occupation during this box.

20 and +20 . 1. 2 Impedance Matching Impedance matching is the practice of making the output impedance of a source equal to the input impedance of the load in order to maximize the power transfer and minimize reflections from the load. Mathematically, it means the load impedance being the complex conjugate of the source impedance. 44) Normally, we can use either lumped networks or distributed networks to match impedance. 1 Lumped Matching Networks Lumped matching networks can be divided into three basic types: the L network, the T network and the pi (π) network.

However, the characteristic impedance of a transmission line is not a distributed parameter but a constant. 5, what is the input impedance? e. 26) where 0 = A2 A1 is called the reflection coefficient at the load and is equal to the ratio of A2 to A1, which are the complex coefficients of the forward and reverse voltage waves at z = 0. 29) This means that the reflection coefficient is a distributed parameter and is a function of the load impedance as well as the transmission line characteristic impedance.

As expected, the electric field is from positive charges to negative charges, whilst the magnetic field forms loops around the current. 5 Summary In this chapter we have introduced the concept of antennas, briefly reviewed antenna history and laid down the mathematical foundations for further study. The focus has been on the basics of electromagnetics, which include electric and magnetic fields, electromagnetic properties of materials, Maxwell’s equations and boundary conditions. Maxwell’s equations have revealed how electric fields, magnetic fields and sources (currents and charges) are interlinked.
