Harry Bergman,Robert S. Hotchkissave been developed for various applications. One important technology for terahertz systems is the design of efficient antennas for terahertz wave transmission and receiving. Accordingly, the terahertz antenna measurement technology is of equal importance as terahertz antenna design. This chapter gi

Infection and Inflammatory Disorderss is explained briefly to obtain the current distribution on the antenna. For a transmitting antenna, input impedances, current distributions, and radiation patterns are shown for four typical antenna lengths. For a receiving antenna, current distributions and reradiation patterns are shown when the

Physics and Mathematics of Radio Wave Propagation in Cellular Wireless Communicationsth loss for a cellular wireless communication. The reason a macro model can provide accurate results that agree with experiments is because the trees, buildings, and other man-made obstacles contribute second-order effects to the propagation path loss as the dominant component that affects propagati

Concept and Applications of Receiving Mutual Impedanceethods for the determination of the receiving mutual impedance are given and illustrated with typical examples of dipole and monopole antenna arrays. The fundamental difference, namely, the truly isolated state between the receiving mutual impedance and the conventional mutual impedance, is explaine
