A small size monopole UWB antenna used for short distance wireless baseband transmission at high data rate

This work presents the design, simulations and measurements of a compact 18×12 mm
²
monopole antenna fabricated on 1.6 mm-thick FR4 substrate for ultra-wideband (UWB) applications. The antenna exhibits a measured voltage standing wave ratio lower than 2 through the 3.1–10.9 GHz frequency range. The Wireless Baseband Transmission (WBT) scheme has been designed to transmit 1 Gbps digital data streams with Manchester or Polar RZ encodings directly between two monopole antennas placed in an emitter-receiver configuration, at a short distance from each other comprised between 1 and 10 cm. The Bit Error rate (BER) has been measured for different digital pattern lengths.
