dc resistance of 50 ohm antenna
Hi, all:
As we know RF components (for example RF load/terminator) has high frequency impedance of 50Ohm (telecommunication), most of them also have DC resistance of 50 Ohm. Why and how do they get 50Ω DC resistance?
How about antennas? Do all of them have 50Ω DC resistance? For example antenna of GSM radio base station.
Thanks.
