Higgler,thank you so much!this antenna is used for a radio telescope to receive 1420mhz radio wave.I've tried a simulation in ADS with 106*96mm patch and 18*16mm for the feeding line ,the center working frequency is perfectly 1420mhz and the impedence matching good(in the origin of the smith...
Hello,
Im doing a design: a patch antenna which works in 1420mhz.It will be put at the focus point of a dish(D=2m)From the rim(angle=65degree)to the center(0degree),there should be a fall of 10dB.I calculated the dimention was:width=106mm,length=86mm.Choose transmission line to feed it.I dont...
