To make an antenna wideband under thin state. The slot antenna includes an antenna element having an aperture type slot, a reflector disposed by opposing to the antenna element, a feeding device which is electrically and physically connected to the antenna element and the reflector, a short-circuiting device which electrically short-circuits the antenna element and the reflector, and a reducing device which reduces the reactance component of the antenna. Since the reducing device for reducing the reactance component of the antenna is provided, the reactance component of the antenna can be reduced even if the antenna is formed thin and the antenna can be made wideband regardless of its thinness.

A process for manufacturing a high frequency multichip module includes a reception inspection step which includes steps of preparing a vertical-type probe, setting the high frequency bare chip on a device stage, and measuring high frequency characteristics of the high frequency bare chip using the vertical-type probe. The prepared vertical-type probe has a center conductor and ground conductors arranged at both sides of the tip portion of the center conductor in the vertical direction in which the probe is pressed to electrodes of the high frequency bare chip. The high frequency bare chip has a ground electrode disposed at the opposite side of the chip from the signal electrodes on the upper surface of a device stage. Then, only a good product is fed to the next step. After the reception inspection, the process goes to a component mounting step. Preferably, the process goes to the next step when the high frequency multichip modules passes at least on of a performance test and visual inspection after the component mounting step.

In a high-frequency probe having a detachable end according to the present invention, parts relating to replacement of an end unit are three parts, that is, an end unit, a probe body, and a pressure block. The end unit comprises a coaxial cable, two slender plate-like ground plates. The coaxial cable is linear in the direction of the end of the high-frequency probe. The ground plates sandwich the coaxial cable. The probe body has an end unit support surface, a circuit board, an end unit arrangement surface and an end part guide. The end unit support surface forms a perpendicular surface used for fixing the end unit to a predetermined position in the end side of the central block in a central part of a surface of the body block. The circuit board connects the end unit to a coaxial connector. The end unit arrangement surface forms a plane in an end side of the body block. And further the guide groove positions and fixes the ground plate in the end part. It is capable to supply positioning pins and a positioning pin holes in mutual contact surfaces for positioning. The present invention makes it possible to adjust characteristic impedance of the probe end part by providing an elastically-shaped part for securing contact pressure and using a pipe or the ground plate in an exposed part of the coaxial inner conductor for performing gap adjustment.
