They are used to radiate and receive THz power. The study of the generation and reception of THz radiation involves both semiconductor theory, electromagnetics, and antenna theory. In this work, after a review of some equivalent circuits for analyzing PCAs, a novel Norton equivalent circuit model is discussed. It effectively describes the coupling between the photoconductor and the antenna. In order to increase the radiated THz power, a connected array solution of PCA is discussed. Connected arrays allow an efficient radiation of the antenna on a large bandwidth and are therefore suitable for radiating the picosecond pulses generated in the photoconductor. In order to realize a connected array of PCA, a proper biasing circuit has to be designed. Such circuit can involve the use of inductors manufactured in printed circuit board technology. Two possible designs of inductor are also discussed.
