Abstract

In this paper, a CPW fed and inversed U-type monopole structure wide slot antenna for novel broadband calacturictics is proposed. To enhance the impedance bandwidth of the wide slot antenna, we proposed the wide slot structure with cpw-fed which is combined with four $\lambda/2$ rectangular radiation modified monopole and inductively coupled. The measured impedance bandwidth is about 2.3 GHz(3.85~6.15 GHz) at 10 dB and the simulated antenna gain is about 6 dBi at 5.4 GHz.
