In this paper, a compact differential-fed antenna with filtering responses is proposed. The antenna is composed of two radiating patches and a differential-fed circuit embedded with two u-shape slots which generate two notches. The stacked patch is employed to further improve the impedance bandwidth to fit the LTE communication application. The proposed antenna achieves the 18% impedance bandwidth...
A photochromic metal‐organic gel with thermo‐, photo‐, and anion‐responsive behavior is obtained. Unusually, heating of the Al–ligand solution leads to gel formation and cooling to room temperature reverses the process to reform the solution. The gel is sensitive to weakly coordinating anions. Additionally, reversible photochromic transformations take place both in the solution and gel states, accompanied...
