Abstract

A Planar Inverted-F Antenna, PIFA, comprises a sheet of conductive material including first, second, third and fourth contiguous sections, the first and third sections extending orthogonally away from the second section and the fourth section extending away from the third section. The sections are folded relative to one another to define a volume with a heights of the second section, a width of the second section, and a depth of the third section extending away from the second section. A supporting pin and a feed pin extend from the second section along an outer edge. A supporting leg extends from either the third or fourth sections, the supporting leg lying outside the plane of the supporting pin to support the PIFA when mounted on a printed circuit board, while allowing components to at least partially occupy the volume under the PIFA.

Dependent claims

A planar inverted-F antenna, the antenna comprising a sheet comprising conductive material, the sheet including:

a first section having a first slot defined therein, the first slot comprising:
a first leg running adjacent a first edge of the first section;
and
a second leg running adjacent a second edge of the first section;
a second section, the second section connected at a first edge of the second section to a third edge of the first section, the second section oriented at a first angle to the first section, the second section comprising:
a shorting leg separated from a remainder of the second section by a second slot, the shorting leg running along a second edge of the second section and terminating in a shorting pin extending from a third edge of the second section opposite the first edge of the second section;
and
a feed pin extending from the remainder of the second section along the third edge of the second section;
a third section, the third section connected at a first edge of the third section to a fourth edge of the second section, the third section oriented at a second angle to the second section;
and
a fourth section, the fourth section connected at a first edge of the fourth section to a second edge of the third section, the fourth section oriented at a third angle to the third section.
