This paper presents the design and evaluation of a compact antenna system with pattern reconfigurability at 2.6 GHz. The antenna is based on the concept of an electronically steerable parasitic array radiator (ESPAR), and its height is reduced by top loading. The antenna can generate 10 reconfigurable patterns with a maximal gain of 7.4 dBi. Furthermore, a multiple antenna system consisting of these antennas is proposed. The radiation patterns realized by this multiple-input-multiple-output (MIMO) system are optimized for automotive urban scenarios based on the results of previous research. The S-parameter measurement results of a fabricated prototype correlate with the simulation. Furthermore, 3D measurements of radiation patterns correspond very well with simulation and gain up to 8 dBi is obtained.
