Symmetry Properties of Antennas in Transmitting and Receiving UWB Signals
We study waveform distortion properties of antennas when transmitting and receiving ultra-wideband (UWB) signals. The impulse response of the transmit antenna is proportional to the derivative of the impulse response of the corresponding receive antenna. The source of this asymmetry and the condition under which it holds are also discussed. The asymmetry property can be derived from the symmetry properties of transmit and receive antennas, both based on the linearity of Maxwell’s equations in isotropic media. The results are illustrated for a UWB pulse and the diamond antenna based on simulations on XFDTD.
