Webthe antenna from service as described in Section 402-421-220. 2. INTRODUCTION 2.o1 The KS-15676 L9 and L14 horn-reflector antennas consist of an electromagnetic horn which illuminates a sector of a large paraboloidal reflector whose focal point is at the apex or feed point of the horn. The paraboloidal reflector WebSince reflector antennas are not efficient when the diameter is less than 8λ, horn antennas or wire antennas are used for a wide-beam antenna whose beam angle is larger than about 8°. On the other hand, the larger reflector antennas are needed to produce spot-beam coverage in the lower frequencies.
WebSep 25, 2024 · A new antenna type is described which combines the low noise temperature characteristics of the horn -ref lector antenna with the more attractive mechanical features associated with the paraboloidal reflector. Cassegrain optics used in an off-set feed configuration enables a virtual source to be formed without sub-reflector blockage. WebThe horn reflector antenna, invented by H. T. Friis in the mid-1940s and in wide use today, uses only a section of a very large parabolic surface as the radiator and is illuminated from the focal point by a tapered horn of either round or square cross section in such a way that the vertical-to-horizontal transition takes place within the ...
