4 Threads found on edaboard.com: Measure Field Strength Antenna
what do you want to detect (1 mV, 100 mV, 2 V, etc)? Whether you will measure something depends on what you use as antenna and the strength of the field.
BAT85 is not the best Schottky diode for a simple UHF detector. Try to find a schottky diode with less capacitance. A very nice detector diode is BAT62 as it has a (...)

I have a question about induction loops, for example those used for hearing assistance or other short-range communication applications. I assume that they are magnetically coupled systems whereby the transmitter generates current in a parallel resonant circuit tuned to a specific frequency. I suspect the receiver has a coil that is

I was woundering how to measure the total electric field strength from different simultaneous sources at a certain point.
what I know is that the antenna factor is useful only if there is an incident plane wave from one direction.
what if there were more than one plane wave? how can the (...)

I need to design an antenna and a rectifier circuit at 27 Mhz in order to measure the strongness or weakness of the 27 Mhz signal by multimeter. please give me instruction for calculation of value of the single diode, rectifier capacitor, resistor
Thank in advance
