In a plane containing an isolated Hertzian dipole, the radiation pattern of the antenna is a: a Circle and the radiation is circularly polarized b Circle and the radiation is linearly polarized c Figure of eight and the radiation is circularly polarized d Figure of eight and the radiation is linearly polarized. The following terms spell the same meaning in reference to an antenna: a Near field and Principal zone b Near field and Fresnel zone c Near field and Fraunhafer zone d Far field and Fresnel zone The standard reference antenna for the directive gain is: a infinitesimal dipole b elementary doublet c half wave dipole d none of the above

It will also appeal to practicing engineers working on antenna development. The text explains both the basic theory of antennas and its application to practical designs. It provides comprehensive coverage and is replete with interesting worked examples and challenging problem sets. The revision represents a thorough updating of material and now includes BASIC programs which can be used for antenna design and computational techniques. Additionally, the book has been reorganized to make it more user-friendly for both students and professionals. The book now covers the fundamentals of various antennas and concepts in the first half of the book and then gets into more details on those same topics later in the book.
