摘要：
The low frequency performance of a proposed combined edge-slot Vivaldi antenna suitable for ground penetrating radar is investigated in this paper. By implementing edge slots in the conductor layer with an inverted triangular parasitic patch element in the aperture, the simulated gain and reflection coefficient parameters are improved compared to the conventional Vivaldi antenna. The modified antenna demonstrates wide impedance bandwith less than -10 dB with positive gain from 75MHz to 1 GHz. A maximum gain above 7 dBi is realized in simulation. With its low frequency operation, gain improvement and low design profile, the proposed antenna is an important candidate for low frequency GPR applications.
