Abstract: An antenna assembly can be configured for RF communications. The antenna assembly can include a ground plane disposed on a substrate. The antenna assembly can include a patch antenna structure spaced apart from the ground plane. The antenna assembly can include one or more grounded posts coupled to and extending from the substrate. The one or more grounded posts can be arranged along at least a portion of a periphery of the patch antenna structure. The patch antenna structure can emit a radiation pattern based at least in part on a transmit signal. The radiation pattern can induce a resultant field in the one or more grounded posts to adjust a characteristic of the radiation pattern.

Abstract: A paper coating pigment is provided which includes a blend of a first and a second discrete aragonitic precipitated calcium carbonate (PCC) particles. The first particles of the blended pigment have an average particle size (APS) of about 0.4 microns and the second particles of the blended pigment have an average particle size (APS) of about 0.5 microns. The blended pigment preferably includes a weight ratio of about 50:50 to about 80:20 with a 60:40 weight ratio being most preferred, respectively, of the first 0.4 micron particles to the second 0.5 micron particles. Also provided are a method for preparing coated paper, which includes preparing the blended aragonitic PCC pigment, adding a binder, and applying the pigment to the paper basestock in a slurry containing a binder and or additives.

Abstract: A high opacity, high light scattering filler pigment for use in wood-containing paper manufacture, comprising by weight 25 to 50% of a fine particle size hydrous kaolin which has been defined as to have particle size distribution such that less than 20% by weight are of less than 0.3 .mu.m E.S.D. and substantially the balance being a fine particle size calcined kaolin.
