A microstrip is a thin, flat electrical conductor separated from a ground plane by a layer of insulation or an air gap. Microstrips are used in printed circuit designs where high frequency signals need to be routed from one part of the assembly to another with high efficiency and minimal signal loss due to radiation. They are of a class of electrical conductors called transmission lines, having specific electrical properties that are determined by conductor width and resistivity, spacing from the ground plane, and dielectric properties of the insulating layer. A microstrip transmission line is similar to a stripline, except that the stripline is sandwiched between two ground planes and respective insulating layers.

Microstrips can also be designed to launch electromagnetic waves into space, in which case they are called microstrip antennas.
