Inverted-E shaped monopole on high-permittivity substrate for application in industrial, scientific, medical, high-performance radio local area network, unlicensed national information infrastructure, and worldwide interoperability for microwave access

In this study, the simulation and measured results of coplanar waveguide (CPW)-fed inverted-E shaped monopole for application in industrial, scientific, medical (ISM), high-performance radio local area network (HIPERLAN), unlicensed National information infrastructure (UNII), and worldwide interoperability for microwave access (WiMAX) bands are presented. The CPW-fed inverted-E shaped monopole is fabricated on a high-permittivity substrate. The lower band is associated with the longer strips of the inverted-E shaped monopole whereas the higher band is associated with the middle and shorter strips of the inverted-E shaped monopole. The proposed antenna has good agreement between the measured and the simulation results. The proposed antenna has a 10 dB return loss with bandwidth 644 MHz (2033-2677 MHz) in the lower band and 1913 MHz (4815-6728 MHz) in the higher band. The proposed dual-band CPW-fed inverted-E shaped monopole covered the ISM, HIPERLAN, UNII and WiMAX bands.
