Embodiment Construction
[0026] The present invention will be further explained below in conjunction with the accompanying drawings.
[0027] Such as figure 1 As shown, an ultra-wideband hybrid antenna for reverberation chamber measurement includes: a ground plate 1, a main radiation module 2 and a secondary radiation module 3 arranged above the ground plate 1, and a fixed main radiation module 2 and a secondary radiation module. Dielectric support 7 of radiation module 3 .
[0028] In this example, the ground plate 1, the main radiation module 2 and the secondary radiation module 3 are all cut from a metal copper plate with a thickness of 1mm, and the overall volume is 375×300×302.5mm 3 (length × width × height), where, such as figure 2 As shown, the main radiation module 2 is composed of the first gradient index curve 4, the first parallel line 5 and the irregular circular arc curve 6, with an overall height of 302.5mm and a width of 289.5mm. The equation of the gradient index curve 4 is y= 0.36...
