As wireless devices shrink, antenna design becomes a critical bottleneck. This guide explores several techniques to overcome ...

Parasitic antenna arrays (PAAs) with a single radio frequency (RF) chain have been used to enable new trends and paradigms for multi-antenna transmission. Significant reduction in hardware complexity, ...

Beyond Towers: The Architecture of Wireless Reach Base station antennas serve as the crucial link between mobile devices and ...

By utilizing low-cost passive elements that reflect signals with varying phase shifts over consecutive snapshots, RIS generates the necessary linearly independent signal components for subspace-based ...

The design of our proposed 2×2 2 × 2 integrated array antenna for IoT applications starts with the design of a single-element passive antenna based on the conventional magneto-electric dipole (CMED) ...

Single-cell transcriptome profiling reveals the spatiotemporal distribution of triterpenoid saponin biosynthesis and transposable element activity in Gynostemma pentaphyllum shoot apexes and leaves ...

Quantum emitters radiate light omni-directionally, making it hard to collect and use the generated photons. Here, we propose a three-dimensional metal–dielectric parabolic antenna surrounding an ...

To increase the transmission efficiency between the satellite and ground system while enhancing antenna gain, for example, they introduced the design procedure, simulation, and measured data of ...
