HFSS S11 of electrically small antenna

    • huyrua291996

      Hello everyone,

      I am simulating an electrically small antenna for 433 MHz. I decide to use length of lamda / 10 because of my limited board.

      But my result of S11 is not true at 433 Mhz. Must I set up like radiation box, mesh or sth to make it right

      Without any knowledge of your design, it's hard to say what the problem may be. However, for very electrically small antennas, it's possible that you may need to incorporate some matching elements into the design to achieve the resonance you're expecting at 433MHz. Hope this helps.
