In this work, by using the VLA archive data, we present the arcsecond scale structure and radio spectrum properties of six UHBLs, which were selected from Nieppola et al. 2006 , including all the UHBLs available with VLA archive data at L, C, X band. Our preliminary result shows that spectrum of UHBLs seems to be steeper than normal HBLs.
