Printed single-layer ACPW stepped-feed monopole antenna for LTE/WLAN band applications

Abstract

The ability of a printed single-layer monopole antenna, which is composed of diamond-fed slotted top-loading, asymmetric co-planar waveguide (ACPW) and stepped-feeding structure, to operate at three wide frequency bands (698∼960 MHz, 1710∼2690 MHz and 3400∼3800 MHz) to cover WLAN and LTE operation has been demonstrated in this article. A prototype of the proposed antenna with 106 mm in length, 0.8 mm in thickness and 15 mm in width is fabricated and experimentally investigated. The experimental results indicate that the VSWR 2.5:1 bandwidths achieved were 71.43%, 48.16% and 13.89% at 700 MHz, 2450 MHz and 3600 MHz, respectively. There is good agreement between the simulated and measured results.
