Abstract
This paper presents the conceptual design of an electrically small antenna (ESA) for transmitting arbitrary wideband signals. Using an ESA, the antenna system converts the baseband I/Q of a broadband signal to a circularly polarized waveform. Consequently, the bandwidth of the transmitted signal is orders of magnitude broader than the antenna’s instantaneous bandwidth. The full-wave simulation results of the antenna system are imported into a circuit simulator to evaluate its performance. These simulation results demonstrate that the proposed method for transmitting an arbitrary waveform from an ESA is effective.
