Design of a modified L-probe fed microstrip patch antenna

A modified L-probe fed microstrip patch antenna is proposed. By replacing the bent part of an L-probe with a printed strip on a suspended substrate and by placing a radiating patch beneath the substrate, the proposed antenna can be more easily fabricated as a planar antenna. As an example, an antenna with this feed has been fabricated for operation near 2.2 GHz and was found to have a broad impeda...
