Özet:

In this communication, the design and analyses of the novel printed ultra wide band ring monopole antenna is presented. The recommended antenna has a pretty small size of 20 x 26 x 1.6 mm3 which is printed on the FR4 dielectric material which has the dielectric constant of 4.4 ad loss tangent of 0.02. The general geometry of the radiating part of the antenna is composed of the circular ring. The antenna has a defected ground structure which has the circular corner points. The antenna feed is placed in asymmetrical position with respect to the x-axis as a the microstrip line. The findings obtained by examining the general antenna performance criteria are presented in a systematic way. The results indicate that the proposed antenna has a suitable performance parameters at the UWB frequency range.
