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: 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: 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: The increased demand for higher data rates in e-commerce, cloud-based processing, social media, and online video streaming is driving the focus towards millimeter wave (mmWave) technology. The mmWave spectrum offers wide bandwidth and low latency, making it suitable for 5G cellular and other communication fields. While single-element patch antennas are compact, they have limitations in bandwidth, gain, and radiation efficiency. Array antennas have shown significant improvements in these areas but have limitations in data rate support. Multiple-Input-Multiple-Output (MIMO) technology can enhance the data rate by spatial diversity and multiplexing techniques. This paper discusses the performance of planar MIMO antenna structures developed at mmWave, comparing them based on bandwidth, gain, isolation, efficiency, and radiation pattern. It also examines the effects of slots, ground structures, and decoupling structures on impedance matching, bandwidth, and isolation levels.

Summary: A compact tag antenna with a stacked planar inverted-L antenna (PILA) structure is proposed for metal-mountable applications in the UHF RFID passband. By inserting a shorted patch into the PILA structure, a double-layered inverted antenna is created, effectively reducing the tag resonant frequency. Experimental results show that the proposed tag antenna has stable resonance characteristics and is insensitive to changes in the backing metal platform.

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.
