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.

An arc-shaped distributed multilayer capacitive loading structure combined with resistive loading is presented in this paper to enhance the radiation performance of folded bowtie antenna (FBA). The radiation efficiency of the loaded bowtie antenna (BA) is improved, and the low-frequency bandwidth is broadened by the bent loop circuits. Additionally, a novel technique of cavity groove is proposed to design the reflector. The optimized cavity tightly coupling with the radiation part overcomes the shortcomings of conventional cavity-backed BAs. The improved ultra-wideband (UWB) FBA with low profile is then designed and fabricated. The basic geometry of the proposed antenna is combined by a novel acorn-shaped bent bowtie patch and a hollowed stepped back cavity. The simulated-10 dB impedance bandwidth of the proposed antenna is over 100 MHz-1100 MHz while the measured operating bandwidth is 250 MHz-850 MHz. This BA of folded type obtains a high realized gain of 4 dBi at 850 MHz and a narrow pattern over the whole band. Time-domain measurements and field tests for practical ground-penetrating radar (GPR) applications have been carried out and the results demonstrate the advanced performance.
