Abstract

In this paper, a CPW-fed monopole antenna using inverted L-type DGS structures is proposed and investigated experimentally. The proposed antenna is fabricated into FR4 substrate with dielectric constant($\varepsilon$r=4.5). Measured results show that the impedance bandwidth, determined from 10-dB return loss, for frequencies between 5.7250Hz-5.825CHz under the condition of VSWR$\leqq$2 is about 540MHg.
