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
