TM Antennas And Radio Propagation ELECTRONIC FUNDAMENTALS SERIES The manuals on electronic fundamentals form a progressive series of educational texts which present the theory and application of electronics for the military services. They understand working mechanisms of linear antennas, aperture antennas, ultrawideband antennas, antenna arrays and leakywave antennas. They are able to evaluate antenna radiation properties by applying concepts and approximation methods. For such antennas, ground has a strong influence on the propagation of the signal. The mode of propagation is called surface wave propagation. Antennas Wave Propagation Prepared By A. Usha Rani Assistant Professor J. Shiva Ramakrishna Assistant Professor G. Nagendra Prasad, Assistant Professor Leakywave antennas Derived from millimeterwave guides (dielectric guides, microstrip lines, coplanar and slot lines)..
