Abstract: A printed circuit board antenna is a diversity polarization antenna for connecting with a printed circuit board. The antenna includes a fixed height connector, a horizontally polarized antenna, and a vertically polarized antenna. The phase center of the vertically polarized antenna coincides with the phase center of the horizontally polarized antenna.

Abstract: The invention provides a vacuum mouthpiece (2) for the acquisition and retention of resected biological specimens for retrieval from a body cavity, the mouthpiece being attached to a first tubular member (4) connectable to a vacuum source and having an active surface including at least one opening communicating with the first tubular member; the mouthpiece (2) being made of an elastically resilient material and having, in a free state, an outside diameter larger than the inside diameter of a second tubular member (24) into which it is insertible by elastic deformation. The invention further provides a closable pouch (20) for the entrapment and retrieval of a resected biological specimen from a body cavity, and a laparoscopic system and method utilizing the above.

Abstract: A phased array antenna includes at least one digital modulator for phase shifting the signal of at least one antenna in the array. Each modulator includes a digital modulating element where the element can be a quadrature modulating element.
