The invention relates to a flush-mounted aircraft, UAV or missile antenna system, which is an integral part of the fuselage () of an aircraft, UAV or missile. The antenna system comprises a surface () made of a conductive material and a resonant recess () formed in said conducting surface, wherein said recess is conformed to provide a resonant behavior in a selected operating frequency, the antenna system further comprising a radiating element () located within said recess and a feeding element () within said recess coupled to said radiating element.

Flush-mounted low-profile resonant hole antenna

In accordance with the teachings described herein, a multilevel ground-plane for a mobile device is provided. The multilevel ground-plane includes a first conductive surface, a second conductive surface, and a conducting strip that couples the first conducting surface to the second conducting surface. A mobile device having a multilevel ground-plane may include a printed circuit board, an antenna radiating element attached to a surface of the printed circuit board, and the multilevel ground plane integral with the printed circuit board and electromagnetically coupled to the antenna radiating element.
