Size Reduction of Octa-Band WWAN/LTE Antenna using Slotted Spirals with Non Uniform Width for Tablets
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 (1710-2690MHz). The size of the antenna was initially 15x40 mm2.
