Wide Band Dual Frequency Circular Slot Anteena With Rectangular Stub at X and Ku Band
The paper presents design and study of the performance of simple circular slot antenna, fed by microstrip line. The dual frequency response having center frequency of 10.58 GHz is observed by using 0.2m.m wide rectangular stub connected with microstrip line. The effect of bandwidth enhancement studies on the return loss performance (-10db) by changing the substrate thickness and substrate material is also being carried out. Dual frequency microstrip antenna becoming very popular day by day for its various applications. One such application is in MIMO Rader. Many methods are used so far for the realization of dual frequency microstrip antenna, like use of different structures in same microstrip antenna using printed circuit technology.
