Integrated Miniature PIFA with Artificial Magnetic Conductor Metamaterials

摘要

Integrated antenna structures described herein may include planar inverted-F antennas (PIFAs) integrated with artificial magnetic conductor (AMC) metamaterials. The integrated metamaterial operatively coupled with the PIFA may function as an artificial magnetic reflector, sending all the energy radiated upwards, and thereby changing the original omnidirectional radiation pattern of the PIFA to a directional radiation pattern. The integrated antenna structures that include PIFAs and metamaterials may maintain a smaller form factor as compared to similar directional antennas, while exhibiting a suitable performance in terms of radiation efficiency, radiation pattern and impedance bandwidth.

1. An antenna structure, comprising:
a printed circuit board (PCB); at least one planar inverted-F antenna (PIFA), configured within a top and bottom layer of the PCB; and at least one artificial magnetic conductor (AMC) cell configured within the PCB, the at least one AMC cell comprising a backing metal layer arranged in a first inner layer of the PCB, and an AMC metal layer formed in a second inner layer of the PCB, the AMC metal layer being configured to have a predetermined shape, wherein the AMC metal layer is configured to reflect energy radiated by the PIFA.
