A millimeter wave Vivaldi antenna with contoured platted vias for next generation wireless communication systems

Abstract

We present a millimeter wave slot coupled Vivaldi antenna (SCVA) for the 5th generation wireless communication systems. The performance of proposed SCVA is studied with contoured platted via holes introduced along the radiating tapered slots. The designed SCVA is compact with a size of 19.3×73.45 mm2. The simulation results show that the reflection coefficient (S11) is less than -10 dB from 24 GHz-40 GHz with an average gain of 13 dBi over the entire bandwidth. The radiation pattern is symmetrical in both azimuth and elevation planes. The dispersion, when ultra-short pulses of 16 GHz bandwidth are received by the proposed antenna, is of value less than 1 %.
