Very low profile multibranch antenna with high-pass matching circuit for LTE/WWAN tablet computer device

Abstract

A low-profile multibranch antenna for the LTE/WWAN tablet computer device is presented. The antenna consists of three branches, an integrated matching circuit and a folded radiation patch. The matching circuit greatly enhance the low-band bandwidth (covering 698~960MHz) without increasing the antenna size. Detail operating principle of the antenna is described in this study. The antenna is disposed on a 0.8mm thick FR4 substrate of size 8 × 40 × 23 mm3. The proposed antenna is fabricated and tested.
