- Abstract
- In this letter, a novel ultra-wideband circular quasi-fractal monopole antenna with a six-petaled lotus pattern is presented. The CPW-fed technique and quasi-fractal concept are used to achieve ultra-wideband characteristics. The size of the proposed antenna is 42 x 50 mm(2) with a lotus diameter of 19.8 mm. The proposed antenna exhibits ultra-wideband characteristics from 2.65 to 12.72 GHz, which corresponds to a fractional bandwidth of 131%. The measured radiation pattern of the proposed antenna is nearly omnidirectional.
