A method of using the center frequency of the fed signal spectrum -10dB bandwidth to design high-power bow-tie time-domain antenna is mentioned. This antenna fed signal is first-order Gaussian pulse. Blumlein formative line specially designed plays a first-order differential role in the process of changing Gaussian pulse produced by Photoconductive semiconductor switches (PCSS) into a first-order...
A broadband electrically small antenna (ESA) based on simplified metamaterial transmission lines (SMTLs) is proposed in this letter. The antenna consists of two different-sized SMTL unit cells of different resonance frequencies. A dispersion analysis of the SMTL reveals that an increase in series of the interdigital capacitance would decrease the 1st-order mode resonance frequency, thus reducing...
This article presents the design and simulation of a low-profile compound spiral antenna with embedded chip resistors and a wideband balun. To obtained low-profile characteristic and solve the problem of bidirectional radiation, a lossy cavity with a horizontal balun is adopted. The simulated and measured results show that the VSWR is less than 2 and the axial ratio is less than 3dB in the frequency...
