Dear frends,
I am stucked with my result of the design
I am preparing an antenna which is 4 Arm Microstrip Spiral Antenna with 4 SMA feeds at 50 Ohms but since the impedance of antenna as theory says is not equivalent to 50 Ohms So i renormalize it to 300 Ohms Can you please check my design and let me know if there is any problem with my design of Antenna. If you also Calculate S parameter using Z parameter from the formula S11 = 20 log (Zin-Zo/Zin+Zo) Which is coming out to be wrong ..
The issue is I am checking at two parameters of HFSS
1. Renomalize all modes at 300 Ohms
2. Do not renormalize
I am not able to understand the results as these above changes are causing change only in S-Parameter but not the Z-parameter
I think it should change the Z-parameter also ..
I dont know what the problem is .
Thank You
