Abstract

The invention relates to an EHF radio measurement technique and can be used to create integrated circuits of the millimeter range. The purpose of the invention is to increase the sensitivity and reduce reflection losses. The EHF detector contains a transmission line in the form of a dielectric rod 1 of rectangular cross section, the side edges of which are adjacent dielectric plates 2 and which is located on a metal plate. A flat conducting frame (SPR) 5 is made quarter-wavelength and located between one side face of the rod 1 and one plate 2. The other plate 2 has a cavity in which a metal screen 7 is installed, the central part of which is made in the form of a flat rectangle placed on the other side face of the rod opposite the CPD 1 5. Thereby a maximum magnetic field strength of the transverse component H _X wave is displaced relative to the axis of the rod 1 to the arranging plane SPR 5, which leads to increased sensitivity. 1 hp f-ly, 2 ill.

The EHF detector contains a transmission line in the form of a dielectric rod 1 of rectangular cross section, the side edges of which are adjacent dielectric plates 2 and which is located on the metal plate end of the dielectric rod I is the input of the EHF detector, and the other is connected to the HF load. conductive frame 5 is made of a quarter-wavelength and located between one side face of the dielectric rod 1 and one dielectric plate 2 ” with a metal plate 3, and another with a low-frequency load (not shown) either through the semiconductor diode 6, or directly in the case when the semiconductor diode 6 is included in the gap of a flat metal frame 5 that can be applied directly to the dielectric core 1 "In another dielectric plate 2, the cavity in which the metal screen 7 is installed is installed, the central part of which is made in the form of a flat rectangle placed on the other side face of the dielectric rod 1 TiaripOTHB plane oh conductive frame 5, and the end parts in the form of bp 1 convex surfaces with the possibility of changing their curvature The EHF detector works as follows

the way

An electromagnetic wave propagating along the dielectric rod 1 excites a flat conducting wave.

frame 5 enters the load 4 in the flat conductive frame 5, an SDS is induced, which is transformed by a semiconductor diode b.

the axis of the dielectric rod 1 to the plane of placement of the flat conductive frame 5, which leads to an increase in the sensitivity
