A planar slotted patch antenna is proposed for ground penetrating radar (GPR). The proposed antenna has a wide bandwidth ranging from 600 MHz to 4 GHz. Tapered slot feeding, curved ground plane, and slot loading are used for a wideband operation, whereas resistive loading is utilized for removal of notch band. Current loops made by slots are bifurcated with the use of 50 Ω resistors. The antenna is designed and optimized to achieve good performance, especially at lower frequencies while keeping the antenna's physical dimension relatively small. The time-domain analysis of the antenna is performed, and the comparative graph is added after analysis to validate its performance in the impulse-based radar. Furthermore, a sandbox test is conducted; the experimental results show the significance of the proposed antenna toward GPR application.
