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

The inverted-F antenna with a parasitic branch (IFA&PB) is widely used in metal-bezel smartphones. Typically, the primary IFA branch is directly fed, while the parasitic branch is excited via ...

Wearable visible light communication systems face fundamental limitations in dense multi-input multioutput configurations due to signal crosstalk between channels. Here, we demonstrate shear-aligned ...

The reflection phase feature of an EBG structure which has two different in-phase reflection phase features is studied in this paper. This EBG structure is applied as high impedance ground plane (HIP) ...
