A novel single L‐shaped open slot antenna for octa‐band metal‐framed smartphones

Abstract

A novel single L‐shaped open‐end slot antenna for octa‐band metallic frame smartphones is presented. The antenna mainly comprises an L‐shaped open slot and a simple LC circuit. The slot is placed at the top of the ground plane which is excited by the 50‐Ω feedline with a band‐stop match circuit. According to the proposed feeding arrangement, the antenna can cover all dual‐wideband LTE/WWAN operations at 698‐960 MHz and 1710‐2690 MHz. A prototype antenna is manufactured and tested. Experimental results such as return loss, radiation patterns, and radiation efficiencies are also presented.

Design of an Antenna With Ground Plane Slots for Lte/Wwan Mobile Phones

“…At present, there are already a lot of researches about the miniaturization and multiband of the mobile phone antennas [1][2][3][4][5][6][7][8][9][10][11][12][13]. In order to better achieve miniaturization and multiband, many technologies have been studied.…”

“…The coupling feed technology [1][2][3] and loading printed distributed inductance technology [4,5] can help to achieve the miniaturization of mobile phone antenna. Loading the matching network [6,7] and reconfigurable technology [8,9] are helpful in achieving multiband of the mobile phone antenna. The slot loaded technology [10][11][12][13] can not only achieve the multiband of the mobile phone antenna, but also improve the impedance matching of the mobile phone antenna.…”
