3 doc.: IEEE Submission, Slide 3 Contents Introduction –Wireless LAN Antenna for Laptop PC –Simulation Technology of Multi Band Antenna Development of UWB Antenna –Basic Design of UWB Antenna –Measurement Results Conclusion & Next Step

4 doc.: IEEE Submission, Slide 4 W-LAN Antenna for Laptop PC Bluetooth LAN Introduction - Suitable for IEEE802.11a/b/g and Bluetooth - Thin Structure (30mm x 30mm x 0.2mm) - High Gain & Omni-directional - Self Ground Plane

5 doc.: IEEE Submission, Slide 5 Return Loss & VSWR Introduction - Micro Coaxial Cable; OD 1.13mm, L=500mm - Time Domain (Gating) Return LossVSWR

6 doc.: IEEE Submission, Slide 6 Average Gain (Horizontal Plane) Introduction 2GHz Band5GHz Band - Micro Coaxial Cable; OD 1.13mm, L=500mm

7 doc.: IEEE Submission, Slide 7 Simulation Technology of Antenna Single Band Antenna Dual Band Antenna Introduction - Capability for Multi Band - Short developing term - Easy Customizing Radiator Design Open Stub Short Stub Simulation Technology Using Equivalent Circuit

8 doc.: IEEE Submission, Slide 8 Target of UWB Antenna –Bandwidth ; 3GHz ~ 6GHz as first generation. -> VSWR < 2.0 –High average gain ; 0dBi (include cable & connector loss) –Omni-directional –Self-Ground Plane –Low Cost & Ready for Mass production

9 doc.: IEEE Submission, Slide 9 Basic Design of UWB Antenna Frequency (GHz) VSWR Image of VSWR Using Triple Band Technology to cover 3GHz to 6GHz Equivalent Circuit of Triple Band Photo of Radiator Patent Pending 123

10 doc.: IEEE Submission, Slide 10 Return Loss & VSWR Measurement Result - Micro Coaxial Cable; OD 1.13mm, L=180mm - Time Domain (Gating) Normalized Bandwidth = 67% (3GHz/4.5GHz) Return Loss PropertyVSWR

11 doc.: IEEE Submission, Slide 11 Measurement System of Antenna Properties Chamber Horn Antenna Sample (Free Space) Network Analyzer

12 doc.: IEEE Submission, Slide 12 Radiation Pattern at 4.5GHz Measurement Result Polarization Vertical Horizontal Measurement at Horizontal Plane - Micro Coaxial Cable; OD 1.13mm, L=180mm Gain (dBi) Measurement Plane

13 doc.: IEEE Submission, Slide 13 Average Gain (Horizontal Plane) Measurement Result - Micro Coaxial Cable; OD 1.13mm, L=180mm

14 doc.: IEEE Submission, Slide 14 Group Delay Measurement Result - Micro Coaxial Cable; OD 1.13mm, L=180mm

15 doc.: IEEE Submission, Slide 15 Conclusion & Next Step Conclusion –Our new antenna covered from 3GHz to 6GHz. –Average gain was around 0dBi. (Coaxial Cable OD1.13mm, L=180mm) –Omni-directional & Self Ground Plane –Group Delay was 1.2ns within this region Next Step –Measurement of the Performance using real UWB System. –Increasing the Band Width up to 10GHz.
