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: This letter presents the design of a compact broadband circularly polarized (CP) array antenna using the Vivaldi element. The antenna consists of four sequentially rotated Vivaldi antenna elements bent into the aperture for miniaturization. A coupling metal patch on the top enhances impedance, circular polarization, and gain characteristics. The measured results show a 10 dB impedance bandwidth of 57.8% and a 3 dB axial ratio bandwidth of 50.7%. The antenna also has a peak gain of 5.6 dBic across the entire operating bandwidth, making it highly miniaturized compared to similar antennas.

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: In a Vivaldi antenna, a symmetrical double-sided structure is introduced to reduce the lower-side frequency. Multiple transverse and longitudinal slots loaded into the redundant conductor layer of the Vivaldi structure can stimulate resonant modes at the higher frequency end, further broadening the antenna bandwidth towards high frequencies. Meanwhile, impedance matching slots are introduced into the conductor layer on the feed side to achieve ultra-wideband (UWB) antenna. The overall size of the final antenna is 23.5 mm x 30.0 mm x 2.4 mm, while the relative bandwidth (S-11 < -10 dB) reaches 142% (2.49-14.78 GHz). This miniaturized UWB antenna has similar directional patterns in the operating band, with an average gain of 4.82 dB.

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 proposes a miniaturized wideband metasurface antenna with +/- 45 degrees dual-polarization. The metasurface is made up of a 3 x 3 array of square patches, and each patch is loaded with a symmetrical quasi-fractal slot. By changing the current path of each patch, the resonant frequency of the metasurface is decreased, and the electrical size is reduced. Experimental results show that the antenna has a wide operating bandwidth and good antenna performance.
