Electronic states of an antiferromagnet UCd$$_{11}$$ and its reference compound ThCd$$_{11}$$ were investigated by means of de Haas-van Alphen (dHvA) effect. From the cyclotron effective mass determined from the dHvA oscillation, the electronic specific heat of UCd$$_{11}$$ was estimated as 100 mJ/K$$^2$$mol, much smaller than 840 in the previous report. The result suggests that magnetic excitation contributes significantly to the specific heat.
