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

Abstract

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.
