  1. Telecommunications Technological Center of Catalonia (CTTC) Pavel Miskovsky Ph.D. candidate Sept. - 2005

  2. UWB Antennas New facilities “Parc Mediterrani de la Tecnologia” • 3.500 m2 building • 3 floors (970 m2 each for utilization) • Offices, meeting rooms, training room, labs and workshops, terrace for antenna use

  3. UWB Antennas • Antenna Requirements: • Low cost • Easy to integrate • Small size • Wide-band • Omnidirectional • CTTC Approach: • Planar technology • Self-Complementary • Bow-tie based topology Double-sided Technology • FCC definition • Fractional bandwidth≥20% or >500MHz absolute bandwidth • 3.1GHz – 10.6 GHz • Short pulses [ns] • No carrier • Gaussian shape and derivates • Without DC component

  4. UWB Antennas Matching/ Filtering Network Matching Technologies Radiating Unit Antenna Subsystem Microstrip To Double-Sided Double-Sided Matching impedance Filtering Double-Sided Bow-tie Shaped • Exploring the potential of double-sides technology in terms of impedance matching, gain and polarization

  5. UWB Antennas Antenna, matching network and technology transformer • Bow-tie shaped antenna with a circle tangent to a 90 deg triangle • feedline width optimized

  6. UWB Antennas Measurements

  7. UWB Antennas Measured radiations patterns, E-plane (xy) copolar crosspolar

  8. UWB Antennas Transfer function dependence on frequency and relative orientation (E-plane) between two identical antennas
