—A novel planar bow-tie aperture antenna is proposed for ultra-wide band (UWB) application in this paper. Beveling technique is employed to increase the impedance bandwidth, and slot loading is introduced to improve the impedance,matching. The measured impedance bandwidth is from 2.7 to 12 GHz for S11 < −10 dB, proving the effectiveness of these two techniques. The measured radiation patterns are relatively stable almost over the entire ultra-wide band of 3.1 to 10.6 GHz with low cross-polarization levels of at least −10 dB. Moreover, the proposed antenna maintains the advantages of ease of fabrication and relatively small electrical size.
