Probe-Fed Hexagonal Ultra Wideband Antenna Using Flangeless SMA Connector

  • 42 Accesses


An ultra wideband (UWB) antenna fed through a flangeless standard SMA connector near one of the vertices of hexagonal patch is introduced here, in this paper. The designed antenna possess a half elliptical but truncated ground plane with a rectangular slot to achieve UWB with monopole radiation characteristics. The antenna prototype provides an impedance bandwidth of 8.3 GHz from 2.3 to 10.6 GHz with a WLAN band rejection of 1.6 GHz from 4.9 to 6.5 GHz. Antenna measurements show that removal of flanges modifies a C-band antenna to an UWB antenna. The demonstrated technique can be utilized to achieve ultra wideband in probe fed antenna. Measurement results match the expectations as predicted by simulation results.
