A novel bandwidth-enhanced UWB tapered slot antenna with Y-shaped corrugated edges is proposed. In the double-slot structure, the two slots are separated by a V-shaped metal surface with straight edges, which is beneficial to improve the directivity of the antenna. Meanwhile, an exponential Y-shaped corrugated edge is designed. This novel corrugated edge not only enhances the impedance bandwidth, but also improves the gain by concentrating the energy near the tapered slot. The impedance bandwidth of the double-slot TSA is from 2.5 to 28 GHz. The gain of the antenna is >10 dB from 3.5 to 25 GHz, and >8 dB in the whole operating band.
