Abstract: A four element 1×4 antenna array with corporate feed structure has been designed and investigated in this paper. Coax feed has been used to power the corporate feed structure. Proposed antenna radiates at the L-band frequency of 1.35GHz which is widely used for the RADAR applications. For the design of corporate feed equal split Wilkinson power divider concepts are been used. FR4 material is been used as base to the antenna which is having a thickness of 62mils. Proposed antenna is having a gain of 6.99dB. 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 14dB which is best acceptable for array applications.
