The Antenna’s Bandwidth and Radiation Pattern Modifying this distance can thus change the performance of the antenna. The distance between the radiators and the surface area of the cone’s end tips are responsible for the reactance of the antenna’s input port. Within each cone, there is a small symmetric cutout that allows for ample clearance for mounting and assembly purposes. Wires, which are modeled as perfect electric conductors, are used to connect the inner and outer conductors of the coax to the conical radiators.

A perfectly matched layer is used to truncate the area of free space surrounding the antenna. This results in a wave that is launched down the coax. This structure houses a small cylindrical domain that contains the antenna’s power source, which is not included within the modeling domain.Īs an alternative, this source can be modeled by implementing a coaxial lumped port boundary condition at the boundary that is facing the coaxial cable. The Biconical Antenna model in our Model Gallery features two conical, metallic, radiating elements, with a dielectric-filled coaxial feed structure at its center. To ensure that the antenna’s design meets these requirements, we can turn our attention to the power of simulation.

It is very important for these antennas to include the broadband characteristics needed to meet such guidelines. This testing ensures that products adhere to the electromagnetic compatibility compliance guidelines that are issued by governing organizations. In particular, the antenna’s two symmetrical radiating cones.īiconical antennas are noted for their use in conducting electromagnetic compatibility (EMC) testing. What allows the antenna to achieve such an extremely wide bandwidth? It can be attributed to its structure. These broadband dipole antennas typically feature a bandwidth of three or more octaves. We explore how simulation can help you ensure this.Ī biconical antenna is a broad-bandwidth antenna that is comprised of two conductive objects, which are cone-shaped. In order to help with this testing, it is important that these antennas possess broadband characteristics. This method provides a novel idea for electric field grading composites with concurrent reinforcement performances in potential applications.When undergoing testing for electromagnetic compatibility compliance, many products rely on biconical antennas. Meanwhile, the dynamic mechanical test reveals that the storage modulus and crosslinking density of the composites are markedly enhanced due to 3D interconnected structure, while the thermal conductivity of this composite is also notably improved by about 300%. The composites exhibit excellent nonlinear electrical properties at a low SiC loading of 4.47 vol%, and introducing different volume fractions of SiC into cellulose aerogel supported epoxy composites can largely broaden the range of switching field. In this study, we report a novel strategy to achieve comprehensive enhancement of thermal, mechanical and electrical properties of epoxy composites with self-assembly surface-modified SiC particles on cellulose aerogel scaffolds.

Therefore, how to realize synergistic optimization of electrical and mechanical performances in ultra-low SiC loading is urgent for practical applications. However, excellent field-grading performance is at the expense of mechanical characteristics due to excess fillers in the composites.
