Abstract

Phased array with wide scanning angle is important to radars, satellite communications and wireless communications. A linear phased array with reconfigurable dynamic Yagi-Uda patch antenna (RDYPA) elements is proposed. The array element consists of one driven patch and some/no parasitic patches/patch. By adjusting the states of array elements, three array modes can be achieved. At each mode, the element has different parasitic patches. The phased array is investigated by simulation and measurement. The simulated scanning angle of the array can cover an elevation range from -72° to 64° by combining three modes and changing the excited phases of elements, with a maximum side lobe level (SLL) less than -7 dB and gain fluctuation less than 1 dB.
