I need an antenna to be low profile (suitable to be mounted on a Helicopter) and that covers GSM upload band (880-915)and UMTS upload band (1850-1980)
A design with a circular polarization is the optimal that i can expect.
I will appreciate any idea or document,
Thank you
Do you have any brilliant idea about an antenna array suitable to be mounted on a Helicopter for the detection of a communication handset that work on 80MHz?
(i appreciate any idea ...)
