Non SUSY Searches at Tevatron
  The Fermilab Tevatron collider experiments, CDF and \dz, have collected over 200 ${\rm pb}^{-1}$ of data at $\sqrt{s}=1.96$ TeV since March 2002 (RunII). Both experiments have investigated physics beyond the Standard Model; this paper reviews some of the recent results on the searches for new phenomena, concentrating on Z', extra dimensions, excited electrons and leptoquarks. No signal was observed, therefore stringent limits on the signatures and models were derived.
