Conical Antennas

A conical antenna, or cone antenna, is a broadband antenna with a cone shape that amplifies signals. Conical antenna are ideal for use in EMC testing, especially radiated emissions testing, to fulfill testing requirements and standards like MIL-STD-461G. One specific form of the conical antenna is the conical log spiral antenna, which are effective in measuring the spectral characteristics of radiation. By placing a conical antenna on the ground, an omni-direction signal can be sent out for even more diverse applications.
