both users need diversity?
I met similar problem at 2.4G band project. After reading the above discussion, we find that there are several means to overcome multipath fading effect, such as hopping frequecy, FEC, interleaving, circularly polarity antenna, spacing diversity antenna. But circularly polarity antenna is difficult to be realised and designed.
1. We usually use wired antenna with mobile end, which is linearity polarity. Microstrip antenna is circularly polarity antenna, however, it occupys large area.
2. Should both communication ends (base & mobile) use diversity technique? My now project situation is this probaly realised within base, difficult within mobile(handset) as the spacing limitation. Any suggestions?
thks.
