Abstract :
The pattern reconfigurable microstrip parasitic array (RMPA) has been reported and its radiation pattern can be switched in three variations using PIN diodes. In this work, the RMPAs are used as elements in a phased array and the electrical behavior of the array are compared to that of a normal patch antenna array. It is expected that the pattern reconfigurability of the RMPA will be able to improve the performance of the array with respect to the patch array, e.g., increase the scan angle and decrease the side lobe level, etc. Because the RMPA is pattern reconfigurable only in the H-plane, all of the arrays to be studied are all H-plane aligned
