Why cross-polarization ratio is important for lineary polarized antennas?
The question reason is one test. I have two wifi 802.11n MIMO modules and did throughput test two times. At first time AccessPoint Tx0 signal goes through attn and cable only to STAtion Tx0, AP Tx1 -> STA Tx1. At second...
Ansoft HFSS Antenna Design kit creates HFSS model of rectangular patch antenna with edge feed at 2.45GHz. In that model I set narrower frequency sweep, add additional analysis with more adaptive passes, adjust Return loss raport to see booth analysis results.
It is normal, that return loss...
But you can feed conventional patch directly from coaxial cable - solder shield to ground plane and center line to patch. You just need to find point in patch with 50Ohm impedance.
So, I try to do same - just create cylinder (material copper), which acts as coaxial center line and waveport at...
Hello,
in google I found one document with some research of patch with notch antenna (document attached). This antenna should have two "resonances" - one at ~2.7GHz, second "resonance" depends from notch size and is ~4.4GHz with 6x6mm notch.
I do simulation with Ansoft HFSS of that antenna...
