A low‐profile wideband dual‐mode (on‐/off‐body mode) dual‐port wearable antenna with flexible substrate is presented for the 5 GHz wireless body area network (WBAN) communications. Using polydimethylsiloxane (PDMS) and felt as substrate, the proposed antenna has a compact structure and is easy to manufacture. In particular, the on‐body mode is realized by the circular patch loaded with a concentric...
A wideband high‐gain millimeter‐wave planar end‐fire antenna based on spoof surface plasmon polaritons (SSPPs) is proposed. A symmetric SSPP transmission line is used to adjust the phase of the wave on the outer edges. By loading metal strips with I‐shaped resonators, a transmission line which exhibits a SSPP‐like behavior is formed. It is used to extend the lower limit of the working bandwidth from...
Based on the finite element analysis and the automatic modeling, the interconnect reliability for GaN monolithic microwave integrated circuit (MMIC) power amplifier (PA) with different transistor sizes, currents, and temperatures have been predicted effectively in this article. The modeling and computation are completed automatically based on the ANSYS Parametric Design Language (APDL) to study the...
