We study how the recent experimental results constrain the gauge sectors of U(1) extensions of the standard model using a novel representation of the parameter space. We determine the bounds on the mixing angle between the massive gauge bosons, or equivalently, the new gauge coupling as a function of the mass MZ' of the new neutral gauge boson Z' in the approximate range (10-2,104) GeV/c2. We consider the most stringent bounds obtained from direct searches for the Z'. We also exhibit the allowed parameter space by comparing the predicted and measured values of the ρ parameter and those of the mass of the W boson. Finally, we discuss the prospects of Z' searches at future colliders.
