Abstract

This letter proposes a spherical inverted-F antenna (SIFA). The radiating element of this antenna is conformally integrated onto one quadrant of a metal-coated foam sphere. The substrate has been recessed into the spherical volume to remain conformal to the spherical host chassis. Design variables are provided in spherical coordinates to describe the structure; this includes the ground, patch, and a spherical foam shell that physically supports the patch and acts as its substrate. Measured and simulated results are presented for a design operating around 400 MHz. \ 2009 IEEE.
