웹The idea of an Infinite Balun is to use the currents flowing on the outside of the coaxial cable as part of the antenna. In this case, we won't need to choke the current at all; we just need to align the cable with where we want the current to flow on our antenna. As an example, consider the spiral antenna . 웹2024년 3월 24일 · Not always necessary. Surprisingly, the use of a balun is not always necessary when feeding a symmetrical antenna with a coaxial line. When the antenna or symmetrical feed line features a point of symmetry where the voltage potential is at a minimum, the shield of the coax may be connected to this point. svd disease

웹2016년 4월 21일 · This paper presents the design of a wideband Balun for Archimedean spiral antenna. The Balun is designed with a microstrip Line (MSL) to parallel stripline (PSL) transition which is used as a balanced feed for Archimedean spiral antenna. This transition Balun has the wideband performance of 194% over the band of 0.5GHz to 18.5 GHz. The … 웹How to connect a Balun to an antenna object?.
