bicone
Description
The bicone
object creates a bicone antenna. A bicone
antenna consists of two symmetrical or asymmetrical cones separated by a small gap. The
feed spans the gap and connects both the cones.
Bicone antennas are broadband omnidirectional antennas used for electronic support measure (ESM) applications. Bicone antennas are often used in electromagnetic interference (EMI) testing for immunity testing or emissions testing.
Creation
Description
creates a bicone
antenna with dimensions for a resonant frequency of 2.3 GHz. The default
bicone has a feedpoint at the apex of the top cone.ant
= bicone
sets
properties using one or more name-value pairs. For example, ant
= bicone(Name,Value)ant =
bicone('Height',1)
creates a bicone antenna with a cone of
height 1 meter.
