    A double-reflector antenna of millimeter range with wide-angle scanning
    (Видавництво Національного університету "Львівська політехніка", 2009) Naumovich, N.; Muravjev, V.; Yurtsev, O.; Moskaliov, D.; Kizimenko, V.; Baty, C.
    It is described the results of numerical simulation and experimental investigation of a double-reflector antenna. The antenna is made according to a certain scheme and it consists of a parabolic reflector (transreflector) horn feed, flat convergent mirror (twistreflector) and a dielectric radome. The transreflector is a thin parabolic radome which has a system of thin wires applied on it. It reflects the waves of linear polarization. The twistreflector turns the plane of polarization around 90.

    Numerical analysis of patch antenna as antenna array element
    (Видавництво Національного університету "Львівська політехніка", 2009) Kizimenko, V.; Bobkov, Y.
    The patch antennas as antenna array element can be modeling by finite element method (programs Microwave Office, Ansoft HFSS and other). But this method need to use fast computer with memory large size. In this work the authors make an attempt to use thin wire integral equation method for patch antenna analysis. The results of modeling by proposed method are compared with the same of modeling by finite elements method and experimental results.
