Summary: This letter proposes a shared aperture scheme based on a tapered slot configuration. The proposed antenna consists of an ultrawideband crossed tapered slot with ground and four 1x4 dipole arrays in the mm-wave band. Metal reflectors are introduced to increase the dipole array gain. The prototype demonstrates a wide impedance bandwidth and high isolation between ports, making it suitable for 5G microbase station applications.

Summary: This paper presents a design of reflector impulse radiating antenna (IRA) with six feeding arms and a printed tapered balun that provides broadband matching to a 50 Omega system. The design is obtained through thorough numerical analysis and optimization. The use of six feeding arms results in lower input impedance while maintaining the same boresight gain as a four-armed IRA. By placing the balun in the antisymmetry plane of the antenna, the boresight gain is preserved and the antenna construction is rigid. Omitting the resistors between the arms and the reflector allows the antenna to handle at least hundreds of watts of power. The compromises made by omitting the resistors are discussed, and the results are verified through measurements of the fabricated prototype.

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.
