✦ Synopsis

spacings considered, 0.045 and 0.09, the highest effective diversity gain is achieved when the source impedance (on transmit) is equal to the complex conjugate of the input impedance of the embedded dipole element. We have also shown that if we try to maximize the radiation efficiency, the increased correlation coefficient will degrade the effective diversity gain more than the improvement in radiation efficiency (for close spacings). Thus, the highest effective diversity gain was obtained when the embedded elements were conjugate-matched to their front-end receivers or transmitters. Then, the correlation between the two antenna ports began vanishing. We believe this conclusion can be generally applied, although we have only shown it for two parallel dipoles.
