19 de may. de 2024 · What's Hot in Antennas and Propagation? In this new #WHAP, the authors Y.-N. Chen, C. Ding, H. Zhu, and Y. Liu present the main highlights of their #ieeetap "A ±45°-Polarized Antenna System With Four Isolated Channels for In-Band Full-Duplex (IBFD)". Read the full paper here
15 de may. de 2024 · However, the antenna design is large and has a complex structure. In 11, an orthogonal circular polarization (CP) MIMO antenna is recommended for 5G operations in the sub-6 GHz frequency range.
Hace 1 día · In this paper, a programmable reflectarray antenna (PRA) for 5G network in S-band is proposed. The first 2-bit reconfigurable polarization-insensitive metasurface with two substrates, three metal layers and only four p-i-n diodes in each unit cell is developed. The top layer of the proposed unit cell is a slotted polygon patch around with two pairs of p-i-n diodes integrated orthogonally. The ...
Hace 2 días · Cross polarization discrimination is the change in received signal strength with change in polarization direction for a linearly polarized antenna. In the case of measurements between dipoles and yagis upto 20dB of change can be observed on changing plane of polarization.
12 de may. de 2024 · El factor de pérdida de polarización de la antena (PLF) es un parámetro crucial en el diseño y análisis de sistemas de antenas. Cuantifica la eficiencia de una antena para recibir potencia en comparación con la potencia incidente, considerando los desajustes de polarización entre las antenas transmisora y receptora.
13 de may. de 2024 · The employment of a circularly polarized antenna improves signal quality and reduces loss. The research work reported in Chen et al. 2023a uses a metasurface loaded with vias for size miniaturization and to realize wideband from 5.46 GHz to 8.46 GHz.
2 de may. de 2024 · Abstract: This paper implements a series-fed microstrip patch antenna with slant-polarization. A 45° inclined cross-shaped dual-polarized microstrip patch antenna array was investigated.
