Abstract A simple method is proposed for the realisation of compact dual‐polarised antennas. The aperture area of a dual‐polarised dipole antenna can be reduced by half by surrounding the antenna with a square loop. Based on the method, a broadba

There are two 5G voice solutions, EPS Fallback and VoNR.In the early stage of 5G network construction, 5G base station coverage rate and terminal penetration rate were not high, so EPS Fallback was used as a 5G voice transition solution.At present, w

Warm blobs are persistently warmer-than-normal seawaters over the Northeast Pacific (NEP), which cause substantial impacts on marine ecosystems and climate. Recently, the warm blobs occurred consecutively in spring and summer of 2021 and 2022. The wa

Abstract An ultra‐wideband dual‐polarized antenna with a low profile is proposed for base‐station applications. The dual‐polarized antenna consists of two crossed dipoles, a square patch, and a square meta‐surface. The ultra‐wideband oper

An embeddable decoupling structure is proposed for massive multiple-input-multiple-output (M-MIMO) antennas in this paper. The embeddable decoupling structure is made up of an end-folded metal strip and a pair of C-shaped metal strips. By introducing

A novel artificial magnetic conductor (AMC) surface based on spiral strips is proposed, which consists of 9 × 9 AMC cells. Each AMC cell includes a spiral strip to increase its inductance, thus featuring a wide bandwidth of 42% for ±90° reflection

Overuse of chemical fertilizers to maintain tea production has caused many adverse effects in tea plantations and largely hampers the sustainable development of the tea industry. Applying bio-organic fertilizer (BOF) to achieve the goal of sustainabl
