In this paper, a compact 8 × MIMO antenna design for 5G terminals is proposed. The consists of two quad-element pairs, each which includes symmetrical T-shaped monopole mode elements and edge-coupled fed dipole elements. size the 38 7 0.8 mm3. monopoles are decoupled by parasitic elements, dipoles grounding strips. Meanwhile, both also orthogonal mode. results show that operating frequency band...

The objective of this paper is to design a parasitic antenna array capable rejecting interfering signals and directing its main lobe towards the wanted signal. designed linear consisting an active monopole fourteen monopoles. method used LMS, making it possible calculate values reactive loads be connected ports elements so that radiation patterns satisfies fixed constraints. simulation results ...

In certain, infrequently occurring, favorable circumstances the ants P. rufescens can display patterns of behavior which seem to be disappearing as a result of their parasitic way of life: the ability to food themselves, independently though ineffectively, elements of the offspring-protection behavior, transporting of nestmates, escape reaction. Similar events reinforce the infrequently used, l...

Parasitic antennas are much lower in cost and complexity than conventional smart antennas. For this reason, they may be considered for use at the portable station. In this paper we study the capacity of a spacedivision-multiple-access (SDMA) system when n element switched parasitic antenna arrays (SPAA) are used for this purpose. As in [1], dynamic slot allocation (DSA) is used with a conventio...

 This paper presents an application of an adapted (R-L-M-C) PEEC method dedicated to the extraction of equivalent circuit of power electronics devices. Two dedicated integral methods with different meshes are used to compute either resistive and inductive elements or capacitive couplings. The adaptive multi-level fast multipole method (AMLFMM) is presented to extract parasitic capacitances on ...

Maintaining mutual coupling suppressing structure as simple as possible is becoming attractive in the electromagnetic and antenna community. A novel parasitic patch structure that can reduce mutual coupling between cavity-backed slot antenna elements is proposed and studied. The structure consists of only a simple rectangular patch inserted between the antenna elements, and it is therefore low ...
