Abstract :
This paper presents compact broadband multimode antennas for MIMO and diversity applications. The antenna system is riot based on spatial diversity. as usual MIMO system, but on a combination of pattern and polarisation diversity. Different modes of self-complementary spiral antennas we used to decorrelate the signals. It is shown that only one antenna is necessary to receive three uncorrelated signals, thus the space required to place the MIMO antenna is very small.
