Single-Anchor Indoor Localization Using ESPAR Antenna
In this paper a new single-anchor indoor localization concept employing Electronically Steerable Parasitic Array Radiator (ESPAR) antenna has been proposed. The new concept uses a simple fingerprinting algorithm adopted to work with directional main beam and narrow minimum radiation patterns of ESPAR antenna that scans 360° area around the base station, while the signal strength received from a mobile terminal is being recorded...

RSS-based DoA Estimation Using ESPAR Antennas and Interpolated Radiation Patterns
In this letter, it is shown how an algorithm, which employs received signal strength (RSS) values in order to estimate direction-of-arrival (DoA) of impinging signals in wireless sensor network (WSN) nodes equipped with electronically steerable parasitic array radiator (ESPAR) antennas, can easily be improved by applying an interpolation algorithm to radiation patterns recorded in the calibration phase of the DoA estimation process....

Low-Reflection Subgridding
Artykuł przedstawia technikę umieszczania makromodeli w trójwymiarowej siatce dyskretyzacji metody różnic skończonych. Umożliwia ona łączenie obszarów siatki o różnym kroku dyskretyzacji. Zastosowana prosta interpolacja liniowa wraz z kolokacją pól sąsiadujących ze sobą podobszarów prowadzi do uzyskania małego współczynnika odbicia od obszaru z gęstą siatką.
