Novel Miniature Semi-Circular-Semi-Fractal Monopole Dual Band Antenna

In this paper, newtype of monopole antenna named Sierpinski-Carpet-Circular (SCC) are introduced. The antenna has design on two frequency bands of 7.5–11 GHz and 13–18 GHz. Furthermore, my design has special radiation pattern. In the other word, this antenna has Conical-Beam and radiation pattern doesn't have notch on top of antenna such as conventional monopole antenna. This behavior occurs, because of change in convention circular shape. I achieved to desirable Return Loss with the two elements from fractal shape add to semi circular geometry. Also, these elements reduce cross-polarization in ϑ = 0° cut. Minimum gain is 7.15 dB in measurement frequency. In results, this antenna has moderate gain. This objective is introduced here hoping for expand branch of fractal shapes in composite to other good shape antenna for multi-band and wideband antenna applications.
