A miniaturized left‐handed circularly‐polarized printed radiator for direct broadcast satellite application

“…The electromagnetic interference impacts of an antenna may be assessed by calculating its CF. [60][61][62][63][64] The determination of the CF is carried out in the following manner.…”

“…Using the prescribed approach, the radiation efficiency ( ) of the antenna prototype is calculated to be 96.43 % at an operating frequency of 12.61 GHz. The electromagnetic interference impacts of an antenna may be assessed by calculating its CF 60–64 . The determination of the CF is carried out in the following manner.…”

“…The contributors of this article stated a miniature printed CP antenna for DBS use. These are the unique features of the prototypes: The antenna has been significantly reduced in size, achieving a reduction of 21.03 % . The antenna provides decent gain and a very impressive bandwidth of 0.8 GHz. It provides complete coverage of the DBS service band in terms of CP bandwidth at 100 % . The antenna offers more than 85 % aperture 51,52 and above 95 % radiation efficiencies, 53–57 respectively. Additionally, it provides a correction factor (CF) of 44.27 dB/m, 60–64 suggesting that it has low impact of EMI/EMC. …”

Application of Automobile Antenna Simulation in Experimental Teaching based on CST

“…The coupling between antenna and antenna, antenna and vehicle body or cable may lead to the deterioration of antenna performance, and seriously affect the work of the whole communication system. The purpose of this paper is to study the electromagnetic compatibility performance of the antenna on the vehicle and evaluate the radiation effect of the antenna on the vehicle based on the antenna orientation diagram [1]- [5]. Electromagnetic compatibility(EMC) is defined as "equipment (system or subsystem) together in their common electromagnetic environment to perform their respective functions of any other equipment is not common to its electromagnetic environment produce electromagnetic interference of a state of coexistence of unsustainable, This includes two aspects: on the one hand, the equipment (system, subsystem) will not be subjected to the electromagnetic emission of other equipment (system, subsystem) in the same electromagnetic environment and lead to the disallowed degradation, that is, it has a certain degree of immunity to the outside world; On the other hand, it will not cause other devices in the same electromagnetic environment to be subjected to the electromagnetic emission of the impermissible degradation, that is, the electromagnetic interference to the outside world is within a certain range.…”
