We present the design, manufacture, and measured performance of a dielectrically loaded
quad-ridge flared horn (QRFH) feed for decade bandwidth radio astronomy application. The …

Reflector-based radio telescopes are used as tools for observations in both radio astronomy
and space geodesy. To observe the weak sources in space, highly sensitive receivers …

We present the design of an ultra-wideband dielectrically loaded Quad-Ridge Flared Horn
(QRFH) feed for the European Very Long Baseline Interferometry Network (EVN) developed …

The 50-meter Large Millimeter Telescope (LMT) operating on the Sierra Negra in Mexico is
the largest single-dish millimeter-wave telescope in the world. Although designed to work in …

Abstract Introduction. Radio telescopes of Very Long Baseline Interferometry (VLBI)
networks usually record several signals with relatively narrow (up to 32 MHz) bands, which …

Radio telescopes are used as tools for observations in both radio astronomy and geodesy.
To observe the weak sources in space, highly sensitive receivers headed by optimized …

This paper considers the potential of the dielectrically loaded Quad-ridge Flared Horn
(QRFH) feed to provide continuous beyond-decade bandwidth in reflector telescopes for …

Современные системы приема и преобразования радиоастрономических сигналов на
радиотелескопах развиваются в сторону расширения рабочей полосы частот и …

Введение. Радиотелескопами комплексов радиоинтерферометрии со сверхдлинными
базами (РСДБ) обычно регистрируются несколько сигналов с относительно узкими (до …
