Design of wide band printed monopole antenna for low rate wireless personal area networks

Abstract

A dual‐band printed monopole antenna useful in low‐rate wireless personal area networks (LR‐PAN) and GPS operation for tablet devices is presented. Antenna has monopole strips arranged in planar configuration on substrate suitable to match standard tablet computer display size. The overall antenna dimension is 150 × 50 × 1.6 mm3. The long and short strips of monopole are separated by notch to increase the bandwidth of antenna. The operating impedance bandwidths of 14.97% and 5.09% are obtained across LR‐PAN band and GPS band, respectively. The presented monopole antenna provides significant gain in order of 4.48 dBi for lower resonant mode and 3.26 dBi for higher resonant mode. The antenna covers LR‐WPAN frequency bands of 868.3 MHz, 915/920 MHz, GSM 850, UMTS/LTE 850, 1.57 GHz GPS bands.

CPW Fed Flexible Graphene Based Thin Dual Band Antenna for Smart Wireless Devices

“…Other Graphene based antennas working in dual-band for millimetre regime and satellite frequencies are also proposed by researchers [13]. The size of this kind of antennas can be reduced further using the concept of electrically small antennas, Fractal Defected Ground Structure with metamaterial-based antennas [14][15][16][17][18][19]. Flexible antennas with CPW feeding technique are preferred in designs because both the patch and the ground plane are printed on the same side of the substrate which reduces the complexity of the fabrication process and no need for vias and short pins when incorporating active devices with the antenna structure [20].…”
