Hi all, this is my first post here, can I detect higher radio frequencies like 500mhz avove with arduino? and how?

Maybe with much additional hardware. With the Arduino alone you can't.

A loop antenna with a diode will work, as shown below:

With loop antenna and diode you can create current and light up led, but frequency is same in the output so it doesn't work for arduino.

jremington:
No, the output is rectified DC, which can be smoothed by a small capacitor and read by analogRead(), or could directly activate an optocoupler for input to digitalRead().

See The Creative Science Centre - by Dr Jonathan P. Hare

Analog read doesn't need to read DC it can read AC, that's why it's analog, anyway after diode it's DC but even with capacitor frequency is same and I can't see any kind of response from arduino.

Can you be more explicit about what you are trying to do?
What do you mean by "detect" radio frequencies above 500 Mhz?

jremington:
Why are you bothering to post on this forum?

Are you a troll?

What?!, If I made a mistake correct me please, asking a question about science isn't trolling, thank you.

It was just an example, I want to know how I can be able to receive analog data in the higher frequencies without external modules.

Why do you want to be able to receive data on frequencies > 500Mhz without using an external module ?

I want to know it's possible or not, If it's not then which module can receive and send data to the arduino In the UHF band.

You really need to describe what it is you actually want to do, you will get far better answers .........

This is your original question, and the answer is "NO". You will need lots of other components, as has been explained.
