What is an aperture coupled patch?

  • A.A patch with an aperture cut in its centre to lower its resonant frequency
  • B.A patch fed by a waveguide aperture placed directly beneath the substrate
  • C.A pair of patches coupled through an aperture in a shared ground plane
  • D.A patch excited through a slot in the ground plane from a line below

Answer: D

In an aperture coupled design the feed line runs on a separate substrate below, and energy passes to the patch through a small slot in the ground plane between them. The two substrates can then be chosen independently, a thin high permittivity one for the line and a thick low permittivity one for the patch. There is no direct connection to solder, and the feed radiation is shielded by the ground plane. It is the most flexible of the feeding methods and the most complex to build.
