Phase shift and antenna

Abstract

The invention relates to a phase shifter and antenna, which is in the field of communication engineering. The phase shift system according to the light shielding consists of a first and second base arranged opposite each other, and a first dielectric layer is arranged between the first and second bases, where the first base includes: the first subbase, and the transmission line is arranged on the side of the first subbase close to the first dielectric layer; Therefore, the second part includes: a second plate, and a reference electrode positioned on the side of the second plate close to the test dielectric layer, the orthogonal projections of the reference electrode and the transmission line on the first plate overlapping at least partially with each other; and a first hole is made on the reference electrode, and the length of the first hole in the first direction is not less than the width of the transmission line.
