Summary: This paper presents a 3D-printed hemispherical lens integrated with a planar ultra-wideband (UWB) antenna. The lens is designed and fabricated from ABS, and it enhances the UWB antenna's high-gain radiation by reducing wave reflection. The proposed additive 3D-printed dielectric lens antenna offers advantages such as ease of design and assembly, low-cost fabrication, and size reduction for high-gain antennas.

Summary: This paper proposes a novel ultra-wideband bow-tie antenna for ground-penetrating radar (GPR) systems. By designing a resistive loaded antenna with a metal reflector and metamaterial loading, the antenna achieves directional gain and high bandwidth. Experimental results show that the fabricated antenna has a lowest frequency of 317 MHz, a relative bandwidth of 98.6%, a peak gain of 9.3 dBi, and a compact size of only 0.38λ at the lowest frequency. Furthermore, the antenna is suitable for deep penetration and high-resolution detection in GPR systems, benefiting the imaging of underground structures.

Summary: This paper proposes a compact stepped slot antenna for ultra-wideband applications, achieving a very small size and wide operating bandwidth. By integrating a stepped slot on the back side and exciting it using a 50 omega-feed line on the top side, the antenna demonstrates a large impedance bandwidth. Additional elementary slots are utilized to further increase the operating bandwidth, resulting in an omnidirectional radiation pattern in the H-plane and bidirectional pattern in the E-plane.

Summary: This paper presents an ultra-wideband dual circularly polarized slot antenna with high isolation. The design incorporates L-shaped probes and a ladder strip to achieve four impedance resonance modes, while a bent strip moderates the impedance to achieve an ultrawide impedance bandwidth. Additionally, L-shaped strips combined with the ladder strip create circularly polarized modes at different frequency bands, and the bent strip creates a third circularly polarized resonance mode. The antenna demonstrates excellent performance with a wide impedance bandwidth, high isolation, and high gain.

Summary: This paper presents a novel high-gain, miniaturized, and ultra-wideband tapered-slot Vivaldi antenna (TSVA) for ice-sounding radar applications. The antenna is miniaturized and its impedance matching and gain are improved by introducing new designs of tapered slot edge, circular cavity, rectangular cavity, inner circular patch, and rectangular slit structures. Simulation and measurement results show that the designed Vivaldi antenna has a 15% reduction in size and a peak realized gain increase of up to 5.1 dBi compared to the conventional antenna.
