Abstract

We present an evaluation of tunable adaptive antenna array performance for achieving useful field patterns. Utilizing antenna elements which can be tuned by a controllable impedance Â¿black boxÂ¿, we characterize the array´s ability to achieve robust patterns for both broadcast and unicast communications. Simulation results demonstrate the impact of these tunable elements and the use of IMPATT diodes is introduced as a means to enable the tunable adaptive antenna array.
