/kæseɡreɪn iən əˈtɛnə/

Meaning and Usage

A Cassegrainian antenna is a type of reflector antenna that employs a feed horn placed at the focal point of a parabolic reflector, which reflects the radio waves towards a second, smaller parabolic reflector. This configuration allows for a more compact design while maintaining high gain and directivity. Cassegrain antennas are commonly used in satellite communication, radio telescopes, and radar systems.

Frequency of Use: The term is specialized and primarily used in technical contexts, such as engineering, telecommunications, and satellite communication. Its usage is more prevalent in written contexts, particularly in academic papers, technical specifications, and industry documents.

Example Sentences

1. The Cassegrainian antenna design allows for effective communication with satellites in geostationary orbit.

2. Дизайн кассегрейновой антенны обеспечивает эффективную связь со спутниками на геостационарной орбите.

3. Engineers opted for a Cassegrainian antenna for the new radio telescope due to its superior sensitivity and resolution.

4. Инженеры выбрали кассегрейновую антенну для нового радиотелескопа из-за ее превосходной чувствительности и разрешения.
