Lab02 - Getting Started with CST Studio
with A Half-wave Dipole Antenna 1
I. Make the following
antenna geometry and find S11 and Z matrix of antenna.
Antenna type: A center-fed
dipole with a circular cylindrical conductor
Design frequency: f
0 = (1.5 + PIN/10000) GHz
½Ç½ÀÁ¶±³ PIN = 0000
Dipole end-to-end
length: L = 0.45 ¥ë
Dipole diameter: d
= L/20
Dipole feed gap at the
dipole center: g = d
Frequency
of analysis: From ( f0 - 1 ) to ( f0 + 1 )
GHz
