Choke structure
WebAbstract: A 2-D choke structure is analyzed by the method of moments (MoM) for the study of isolation characteristics between closely arranged two waveguide slot array antennas. … WebIn this study, we demonstrate an Nb5N6 terahertz (THz) detector with radio frequency (RF) choke-enhanced dipole antenna structure for 0.3 THz detection. The maximum electric field intensity of 218 V/m is obtained by optimizing the parameters of the dipole antenna with RF choke. Compared to a dipole antenna without RF choke, the electric field intensity of …

By introducing some matching posts in the structure, a wideband design is achieved with 55% bandwidth covering from 11 to 19.5 GHz, where the insertion loss is lower than 0.28 dB. In electronics, a choke is an inductor used to block higher-frequency alternating currents (ACs) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core, although some consist of a doughnut-shaped "bead" of … See more Chokes are divided into two broad classes: • Audio frequency chokes (AFC) – designed to block audio and power line frequencies while allowing DC to pass • Radio frequency … See more • Line reactor • Waveguide choke - designed to enhance or inhibit propagation of specific modes in waveguides.
