Summary: This paper proposes a step-by-step design procedure for obtaining independent dual band-notch performance in a tunable dual band-notched UWB antenna. The proposed antenna consists of a semicircle ring-like radiating patch, an elliptical-shaped slot, double split ring resonators, and a defected ground structure (DGS). By loading varactor diodes and changing the reverse bias voltage, a wider band-notched tuning range can be achieved. The experimental results show efficient suppression of narrow-band interference signals and improved antenna operating performance. The proposed antenna has a simple structure, low profile, compact size, and extensive independent tunable range.

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.

Summary: This paper proposes a novel high gain antipodal tapered slot antenna for high resolution imaging applications in the frequency range of 20-40 GHz. By designing the radiating fins of the antenna as elliptical and circular shape for inner and outer tapers respectively, and incorporating an isosceles trapezoid-shaped dielectric lens and anisotropic left-handed metamaterial unit cells, the antenna achieves high gain and stable radiation pattern.

Summary: Compact fifth-generation (5G) low-frequency band filtering antennas with stable directive radiation patterns, improved bandwidth, and gain are designed, fabricated, and tested in this research. The proposed filtennas combines compact 5G third-order uniform and non-uniform transmission line hairpin bandpass filters with the compact ultrawide band Vivaldi tapered slot antenna in one module. Computer simulation technology software is used for the simulation, and good measured S11 and peak realized gains are achieved for the filtennas, outperforming the predesigned filters.

Summary: A new theory called Vivaldi nonuniform slot profile antenna (VNSPA) is proposed to reduce the size of the predesigned compact ultrawide band (UWB) Vivaldi-tapered slot antenna (VTSA) without compromising its performance. The proposed antenna achieves a significant size reduction and maintains similar matching and bandwidth performance compared to VTSA. Experimental results validate the effectiveness of the new theory.

Summary: By introducing a V-shaped air slot in the antenna substrate, the peak gain of traditional Vivaldi antennas can be significantly improved without increasing size or adding extra components. The air slot helps to distribute electromagnetic waves more evenly, enhancing peak gain particularly at higher frequencies. Experimental results demonstrate that the combination of air slot and removal of back substrate can effectively enhance antenna performance.
