Abstract: A four element 1×4 dielectric resonator antenna array with corporate feed structure has been designed and investigated in this paper. microstrip feed has been used to power the corporate feed structure. Proposed antenna radiates at the C-band frequency of 6.5GHz which is widely used for the RADAR applications. For the design of corporate feed equal split Wilkinson power divider concept is been used. Arlon material has been used as base to the antenna which is having a thickness of 0.79mm. Proposed antenna is having a gain of 12dB. From the return loss and smith chart plots we can observed the impedance matching characteristics of the antenna array. A beam width of 250 is obtained with a SLL of 15dB which is best acceptable for array applications.
