 In this article a single notched ultra-wideband antenna which is integrated with dielectric ring resonator is proposed for cognitive radio applications. The proposed antenna consists of elliptical base and a split ring resonator on either side of the feedline for bandwidth enhancement. The rectangular dielectric resonator which is proposed is a rectangular dielectric resonator which give good isolation between the two ports. The proposed antenna has single rejection at 5.7GHz-8.4GHz at ultrawideband region. The proposed antenna has a peak gain of 6dB and average gain of 3. 1dB.Commercially equipped tool ANSYS EM 17 is used to characterise the proposed antenna. The proposed antenna provides good isolation between the two antenna ports confirming efficient integration. The antenna is best suitable for candidate of radar applications, medical imaging and cognitive radio systems.

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.
