Aperture-coupled planar inverted-F antenna

摘要: An aperture-coupled planar inverted-F antenna (PIFA) including a radiating patch formed on one side of ground plane and separated therefrom by first dielectric which may be air, foam or another suitable material. A shorting strip connects the to at point corresponding dominant mode null, such that size reduced factor two. microstrip feedline is arranged an opposite second part substrate printed wiring board Signals are coupled between via aperture in plane. The use coupling avoids excessive cost associated with conventional TEM transmission line coaxial feeds, while providing improved manufacturability ease integration relative PIFAs feeds. Moreover, provides tuning flexibility. For example, portion used as stub provide impedance matching feedline.
