| dc.description.abstract | The report is a planning of create a circular antenna with in radio frequency
which applies some knowledge about antenna engineering to build it for learning about
the diffraction of waves and parameter in antenna. For example, reflection coefficient
(S11), voltage standing wave ratio (VSWR), impedance, and radiation pattern. The test
should calculate a radio frequency and the aerial were made by the CST Microwave
Studio program. Then, uses stainless steel to create all of a circular aerial after
calculates diameter antenna. After that, brings it to do the parameter test for compare
in the CST Microwave Studio program. For the aerial testing, uses some equipment like
MFJ, the Signal generator, the Spectrum analyzer, and Network analyzer to do the
parameter test. In conclusion, the result of the aerial testing has the same tendency
with the theory which had learned before | en_US |
