Non-Planer Parasitic of Semi-Fractal patch Antenna with Multi Ring Structure for Multi Band Applications

Abstract

A new A new form of hybrid design of a microstrip-fed parasitic coupled ring fractal monopole antenna with semi ellipse ground plane is
proposed for modern mobile devices having a wireless local area network (WLAN) module along with a World-wide Interoperability for
Microwave Access (WiMAX) function. In comparison to the previous monopole structures, the miniaturized antenna dimension is only about
30 x 40 x 0.8 mm3, which is smaller than the previous proposed design. By only increasing the fractal iterations, very good impedance
characteristics are obtained. Throughout this letter, the improvement process of the impedance and radiation properties is completely presented
and discussed.
