DUAL-BAND BEAM SCANNING REFLECTARRAYS AND NOVEL WIDEBAND AND ... Dual-band Beam Scanning Reflectarrays and Novel Wideband and Polarization Diversified Planar Antennas. (August 2008) Shih-Hsun Hsu, B.S., National Cheng Kung University; M.S., University of Wisconsin-Madison Chair of Advisory Committee: Dr. Kai Chang The reflectarray antenna has been considered as a suitable candidate to replace the A Compact UWB and Bluetooth Slot Antenna for MIMO/Diversity ... A novel compact pattern diversity slot antenna for ultra-wideband (UWB) and Bluetooth applications is presented. This antenna consists of two modified coplanar waveguides that feed staircase-shaped radiating elements, wherein two different fork-like stubs are placed at the 45° axis. CPW Fed Monopole Antenna for Future UWB Diversity Application ...
A conical reflector antenna is disclosed with a feed that is either a close approximation to a line source or a cylindrical structure which is electrically equivalent to a line source.
(PDF) Four Ports Wideband Pattern Diversity MIMO Antenna Keywords: broadband antenna, pattern diversity antenna, slot antenna and ultra wide band (UWB) antenna. Abstract-In this paper a broadband four ports MIMO antenna with pattern diversity is presented. DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR ... Figure 7: Radiation patterns of annular slots when n=0 and W s<< ... The annular slot antenna consists of a circular slot on a square, metal ground plane that is fed by a microstrip line, designed on the bottom of the Duroid substrate. The Dual-band-notched antenna for UWB MIMO applications ... Two antenna elements are placed side by side and fed with matched microstrip lines on a substrate with an area of 35 × 30 mm 2. Notched characteristics at WiMAX (3.4–3.6 GHz) and WLAN (5.725–5.825 GHz) have been achieved using complementary split ring resonator (SRR) slots etched in both the antenna elements.
Microstrip slot antennas have numerous promising features but they suffer from undesired modes.single slot (c) five slots. The third design of antenna is fabricated and tested the simulated results[9] H. Sabri and Z. Atlasbaf, “Two Novel Compact Triple- Band Microstrip Annular-Ring Slot Antenna...
