Abstract :
A novel reconfigurable two elements antenna array for IMT-advanced MIMO system is proposed. The array includes two microstrip antennas with two PIN diodes respectively. By switching the states of PIN diodes, the available part for radiation can be changed, and each antenna element can operate on two operation bands, two orthogonal polarizations and has distinct radiation patterns. Each antenna element has a compact size smaller than 13 mm in square. For these flexible features, the proposed antenna array has good potentials for the adaptive MIMO systems in handheld terminals.
