Abstract :
A low profile diversity antenna for MIMO application is introduced. The design is based on a double folded dipole antenna filled with a slab of ceramic of εr=6. Two diversity antennas operating at 5.2 GHz are designed and implemented on a handset for IEEE.11a wireless systems. The isolation is found to be better than 20 dB in both measurement and simulation and measured bandwidth is about 250 MHz at -10 dB. Simulated and measured radiation patterns are close to each other. The envelope cross-correlation is calculated to be much less than 0.1 and the ratio of the mean effective gain between the antennas is close to unity.
