Abstract
The effect of slotted spiral technique on an antenna that covers octal bands of WWAN/LTE has been studied and discussed in this paper. The Slotted Spiral consists of strips arranged together forming a spiral of different vertical and horizontal width. The antenna has been initially designed without employing the slotted structure to cover the frequency bands GPS l2 band-1227. 60/l3 band 1381. 05, DCS1800 /PCS1900/ UMTS2100 LTE2300/2500/2600 (1710–2690 MHz). The size of the antenna was initially 15 x 40 mm2. Then the structure has been designed employing the slotted spiral technique which provides a size reduction from 15 x 40 mm2 to 15 x 38 mm2 which is small enough to be incorporated in a tablet computer. Furthermore the use of embedded parallel resonant structure aids in implementing slotted spiral technique. The antenna after employing size reduction provided a low return loss and good radiation efficiency and high gain than the antenna without slotted spiral.
