the total hilbert patch antenna size is 10cm×10cm,the wire width is 0.5mm,the order is 6.
then anybody can participate the lowest resonant frequency?
what software can be used to calculate the the resonant frequency or s11?
and how to use the network analyser to test the S11 espcially at low frequency(10MHz-100MHz)? i found the result will easliy be influenced by the enviroment. for example when i was close to the antenna the result will change!
pls help me! thanks!

depends on feed point.there are papers by V.Varadan, K.J.Vinoy and K.A.Jose that give you a fair idea.low freq. VNAs do exist(r&s)
