Supershaped CPW-fed Monopole Antenna With Parasitic Strips for Unidirectional Pattern

In this paper, a supershaped CPW-fed monopole antenna with parasitic strips for unidirectional pattern is proposed. A Gielis curve based patch with planar reflector and parasitic strips are used to enhance the directivity. The characteristics of the antenna such as return loss, realized gain and radiation pattern are simulated and the return loss is compared with the measured results. The -10 dB impedance bandwidth of the designed antenna is from 2 GHz to around 10 GHz with the peak gain around 4 dB or above for most of the frequency range.
