Harris’ Q134 Antenna offers the latest in fully conformal, low RCS antenna. The Q134 antenna capitalizes on Harris’ proven annular-slot technology providing a 3.7:1 operating bandwidth, which exceeds the useful bandwidth of most blades and other exposed apertures. In addition to the broad operating bandwidth, the Q134 also
Broadband Circularly Polarized Annular-Ring Microstrip Abstract: A wideband circularly polarized (CP) annular-ring patch antenna with two proximity-coupled L-probe feeds orientated to have phases of 0 deg and 90 deg, using a broadband 90 deg hybrid feed, is proposed. It is found that the current distribution for CP operation can be improved by cutting a smaller concentric circular slot on the original larger circular patch to form an annular-ring TANGENTIALLY FED BROADBAND ANNULAR SLOT … 2009-11-12 · TANGENTIALLY FED BROADBAND ANNULAR SLOT ANTENNA FOR WLAN APPLICATIONS Philippe Minard, Ali Louzir THOMSON multimedia, Corporate Research 1 Avenue Belle-Fontaine, BP 19, 35511 Cesson-Sévigné Cedex – France Pattern and Frequency Reconfigurable Annular … 2011-8-18 · Pattern and Frequency Reconfigurable Annular Slot Antenna Using PIN Diodes_专业资料 108人阅读|11次下载 Pattern and Frequency Reconfigurable Annular Slot
