Understand the design principles and working characteristics of biconical antennas

Biconical Antenna is a special wide-band antenna whose structure consists of two symmetrical metal cones connected at the bottom and connected to the signal source or receiver through a trim network. Biconical antennas are widely used in electromagnetic compatibility (EMC) testing, wireless communications and radar systems. The working principle of the biconical antenna is to utilize the reflection and radiation characteristics of electromagnetic waves on metal conductors. When an electromagnetic wave enters a biconical antenna, it will be reflected multiple times on the surface of the cone, forming a multipath propagation effect. This multipath propagation causes the antenna to produce a relatively uniform radiation pattern in the radiation direction. The main feature of biconical antennas is their wide-band performance. It can operate over a large frequency range, typically covering a few hundred megahertz to several gigahertz. This characteristic makes biconical antennas widely used for wide-band wireless communication testing and measurement, as well as EMC testing of equipment in different frequency ranges. In addition, the structure of the biconical antenna is relatively simple and easy to manufacture, install and use. However, biconical antennas also have some limitations. First, the gain of the antenna is relatively low due to its broadband performance. Secondly, since the design and manufacture of antennas need to consider frequency range and other requirements, there may be different antenna characteristics on certain frequency bands. Therefore, it is necessary to select the appropriate biconical antenna according to specific requirements in the application. In general, the biconical antenna is a special antenna with wide-band performance and is suitable for wide-band wireless communication, EMC testing and measurement. It has the advantages of simple structure, easy manufacturing and use, but attention needs to be paid to the selection of gain and different frequency band characteristics.
