Hi.
I'm designing a low power RF device with the CC1101 radio from texas instruments on the 433MHz band. I have some knowledge on transmission line theory but none on antenna theory, so i'm having difficulty answering some questions.
The device that i'm building has the area of a credit card and must have a range of at least 150m. This constrains are not making my life easy.
The questions that i have are; which antenna should i choose, a small helix or a monopole? How important is the ground plane size and its orientation relative to the antenna?
If anyone could give me some directions i would be very gratefull.
Thanks on advance.
Nuno
