马建平同志发明的高增益反射式聚焦天线,确切地说应认为是超增益天线。因为面状天线的增益通常可由式G_▲=(πD/λ)~2η来表示,若天线效率η在0.6以上直到趋于1时,均可认为是高效率、高增益天线。超增益反射式聚焦天线的直径D为1.2m,张角2ψ_0为130°,波长λ_0≈7.9cm,它的增益值并不服从于
The high-gain reflective focusing antenna invented by Comrade Ma Jianping should be considered as a super-gain antenna. Because the gain of the planar antenna can usually be expressed by the formula G_ ▲ = (πD / λ) ~ 2η, if the antenna efficiency η is more than 0.6 until it reaches 1, it can be regarded as a high efficiency and high gain antenna. The super-gain reflective focusing antenna has a diameter D of 1.2m, an aperture angle of 2ψ_0 of 130 °, a wavelength of λ_0≈7.9cm, and its gain value does not obey
