The need for a global research effort to establish the current understanding of climate change adaptation and mitigation at the city level is urgent. To meet this goal a coalition of international researchers - the Urban Climate Change Research Network (UCCRN) - was formed at the time of the C40 Large Cities Climate Summit in New York in 2007. This book is the First UCCRN Assessment Report on Climate Change and Cities. The authors are all international experts from a diverse range of cities with varying socio-economic conditions, from both the developing and developed world. It is invaluable for mayors, city officials and policymakers; urban sustainability officers and urban planners; and researchers, professors and advanced students. 517 3 $aClimate Change & Cities 606 $aUrban ecology (Sociology) 606 $aClimatic changes$xRisk management 606 $aClimate change mitigation 606 $aUrban policy 615 0$aUrban ecology (Sociology) 615 0$aClimatic changes$xRisk management. 615 0$aClimate change mitigation. 615 0$aUrban policy. 676 $a363.349217091732 702 $aRosenzweig$b Cynthia 712 02$aUrban Climate Change Research Network, 801 0$bUkCbUP 801 1$bUkCbUP 906 $aBOOK 912 $a9910465303903321 996 $aClimate change and cities$92482164 997 $aUNINA LEADER 03564oam 2200481 450 001 9910483807303321 005 20210528192734.0 010 $a981-15-9089-3 024 7 $a10.1007/978-981-15-9089-4 035 $a(CKB)4100000011631484 035 $a(DE-He213)978-981-15-9089-4 035 $a(MiAaPQ)EBC6420710 035 $a(PPN)252513312 035 $a(EXLCZ)994100000011631484 100 $a20210528d2021 uy 0 101 0 $aeng 135 $aurnn|008mamaa 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aOmnidirectional slots antenna /$fJunping Geng 205 $a1st ed. 2021. 210 1$aGateway East, Singapore :$cSpringer,$d[2021] 210 4$d©2021 215 $a1 online resource (XXV, 170 p. 121 illus., 104 illus. in color.) 311 $a981-15-9088-5 327 $aIntroduction -- Basic Theory of Omnidirectional Antenna and Slot Array -- Principles of Omnidirectional CP Slot Array Antenna -- Principles of Omnidirectional Dual-CP Slot Array Antenna -- Dual CP Polarization Diversity and Space Diversity Antennas Enablaed by a Compact T-shaped Feed Structure -- Circular Truncated Cone Slot Antenna with Circular Polarized Conical Beam -- Half-space Covered Antenna for Air-ground Communication -- A Compact Reconfigurable Coaxial Slot Antenna -- The Omnidirectional/Directional Switchable Antenna based on the Curved Microstrip Antenna with Defected Ground Structure. 330 $aOmnidirectional antenna with high gain, low profile, vertical polarization, even CP polarization is very difficult to design, although it is from the dipole. In this book, a novel idea that the running wave in the coaxial wire is disturbed by the orthogonal slot array on the cylindrical metal shell is introduced, which radiates the CP wave in omni-direction. When feeding on two ends of the coaxial wire respectively, there will appear left hand circularly polarized (LHCP) omnidirectional radiation or right hand circularly polarized (RHCP) omnidirectional radiation. By introducing the T-shaped feed structure, the coaxial wire with slot array can conveniently produce the LHCP and RHCP radiation diversity with one end feeding. In the further, combining with the directional antenna, it will generate the pattern diversity in the half-sphere space. The antenna of the coaxial wire with slot array can further transform into conical CP beam antenna if the coaxial wire becomes into a conical frustum. By introducing the PIN diode into the slot, the antenna of the coaxial wire with slot array can radiate the reconfigurable directional beam by switching the states of the PIN diodes. By introducing a novel switchable microwave circuit, the omnidirectional /directional pattern switchable antenna can be realized easily. This book proposes a continues method to develop the potentialities of the omnidirectional antenna. And the readers can study the method or ideas of the omnidirectional antenna, even graft the CP or diversity methods to other antennae. 606 $aAntenna radiation patterns 606 $aElectromagnetic waves$xPolarization 606 $aAntennas (Electronics) 615 0$aAntenna radiation patterns. 615 0$aElectromagnetic waves$xPolarization. 615 0$aAntennas (Electronics) 676 $a621.3824 700 $aGeng$b Junping$01077550 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bUtOrBLW 906 $aBOOK 912 $a9910483807303321 996 $aOmnidirectional slots antenna$92848018 997 $aUNINA
