1
The Discone Antenna in UWB Communication System

2
The configuration of the Discone antenna
The antenna has good traditional parameter like
return loss
3
Filtering effect of the antenna
4
Transfer functions are different at different
angles
5
Receiving Transfer functions impinging from
different direction
6
The distortion caused by transmitting and
receiving of the antenna
7
The Reciprocity Theorem
8
The reciprocity relationship verification for
broadside direction
9
The antenna effect at LOS situation
The antenna effect was studied in a BPSK DS-UWB
system. The impulse response of the transmitting
and receiving antenna were simulated from CST.
The indoor propagation model was simulated by ray
tracing model.
10
The antenna effect at NLOS situation

Conclusions
  • The antenna has greater impact in UWB than in
    narrowband systems as the large bandwidth of an
    UWB signal causes substantial changes in both
    radiation pattern and the input impedance.
  • Reciprocity can be used to produce the receiving
    transfer function if the transmitting transfer
    function is known or vice verse.
  • The performance evaluation of UWB system must
    include the antenna effect.
