Wexford, Ireland [email protected] +353 53 9169500 www.taoglas.com 1.0 Introduction This flexible wideband ultra wide band antenna has been designed by using DIT Antenna High Frequency and Research Centre patented antenna design methodology in Dublin, Ireland. Taoglas and DIT have developed this range of solutions following years of expertise and collaboration in design of high performance ultra wide band antennas for wireless devices. LTE system antenna (100x38x0.1mm) Taoglas have designed an ultra wideband antenna solution for global LTE “4G” systems. The bands are 690 MHz – 940 MHz and 1720 MHz – 3130 MHz. The antenna is delivered on flexible circuit material which is ideal for the radiation patterns of antennas with higher frequencies and wider bandwidth. The efficiencies of the antenna are over 70% across the bands. This material allows the antenna to be placed on the edge of a PCB and folded over the PCB or folded upwards and adhered to the device housing itself. The antenna is currently available with cable and connector and its own ground plane for evaluation purposes. © All Rights Reserved Taoglas Limited, Unit 7 Peare Campus, Moyne Business Park, Enniscorthy, Co.

HGP = Ground plane length (mm) © All Rights Reserved Taoglas Limited, Unit 7 Peare Campus, Moyne Business Park, Enniscorthy, Co. Wexford, Ireland [email protected] +353 53 9169500 www.taoglas.com wgp = Ground plane width (mm) The performance of the antenna remains quite stable on different points of a PCB as can be observed from parametric sweeps of the antenna at an offset location x on the ground plane. © All Rights Reserved Taoglas Limited, Unit 7 Peare Campus, Moyne Business Park, Enniscorthy, Co. Wexford, Ireland [email protected] +353 53 9169500 www.taoglas.com 4.0 S11 Measurement Six different ground plane configurations have been tested: 1) Orthogonally displaced on the edge of an 80 x 40 mm2 groundplane; 2) Co-planarly displaced on the edge of an 80 x 40 mm2 groundplane; 3) Orthogonally displaced on the edge of a 100 x 40 mm2 groundplane; 4) Co-planarly displaced on the edge of a 100 x 40 mm2 groundplane; 5) Orthogonally displaced on the edge of a 200 x 200 mm2 groundplane; 6) Co-planarly displaced on the edge of a 200 x 200 mm2 groundplane. The antenna presents a versatile behaviour and offers a good impedance matching and radiation performance for different grounding solutions. In particular, it offers 6 dB return loss bands (5 dB at the edge) over the ranges 690 – 960 MHz and 1.71 – 2.69 GHz (LTE bands) for the configurations 4, 5 and 6. But for the configurations 1 and 2 its performance is very close to LTE requirements. This suggests that this antenna can be allocated into small devises either orthogonally or co-planarly displaced at the edge of the chipboard. The co-planar configuration might be suitable for small (~ 80/100 x 40 x 33 mm3) and low-profile devises. © All Rights Reserved Taoglas Limited, Unit 7 Peare Campus, Moyne Business Park, Enniscorthy, Co.
