What will be the impact on Antenna performance to shift the resonant frequency by RLC Matching network?

There is always a possibility to shift the resonance frequency by adding a RLC matching network. I wonder what will be the consequence on antenna performance (axial ratio, gain)? If there is no...

Why Antenna shows negative gain even though it has very good matching?

I am aware of the fact that electrically small antennas are poor radiators with very small gain and low efficiency. One main cause of this is poor matching. An extremly electrically small antenna...

What is the impact of image current from ground plane on patch antenna? I wonder how it radiates if ground plane is very near to radiator?

As we know, patch antenna is combination of two magnetic dipole. If we place a perfect electrical conductor near a dipole, antenna performance will suffer significantly. Then how a patch antenna...

I am getting two peaks at 702 and 705 eV for Fe 2p scan of a composite made from Fe-salen.how it can be explained?

the pure Fe-salen spectra is in conformity with literature,but the composite is showing two extra peaks at 702 and 705 eV. Can anybody explain about why the peaks are coming.

What will be the cororidinate(theta and phi) to evaluate the axial ratio?

I have designed a circular polarized antenna. But , I am confused with cor-ordinate system. In some angel it shows less than 2 dB axial ratio and some other point it shows more than 10 dB like a...

Why there is a big difference in between realize gain and gain in my design?

I have designed a multiport antenna. Where as, I have 2 dB Gain but realize gain is -6 dB. Point to be noted, S11 is really good. I have -25 dB return loss at my desired frequency.
