    S11 for practical antennas

    Thanks for the reply . Any tips on improving the gain (Currently I am working on an Inverted F PCB antenna and a gain of about 4.3dBi). Also any points to consider while designing a dual band antenna considering that we require high bandwidths for the two resonance frequencies.

    S11 for practical antennas

    What value of S11 is required for practical antennas . Is it less than -10dB or -6dB ?

    how to get a good radaition pattern of patch antenna

    It is highly dependent on what you are using the antenna for. In case you need the antenna to be used with base station , it should be omni directional and this response is not good , whereas if you need it places where a more directional response is needed then this will be better . Apart from...

    Inverted F antenna bandwidth

    Currently I am designing dual band IFA antenna for GSM900 and DCS using CST. But I am finding it really hard to get the required amount of bandwidth. Can anyone share techniques by which I can increase the bandwidth ? Thanks in advance.

    Hfss designing matching

    I am trying to design a L match in my antenna to tune my antenna to a particular frequency. I am using this configuration. I have made the inductance and capacitance using LumpedRLC boundary excitation.I am also adding the screenshots of my current setup The L match does not tune my...
