Abstract: An example apparatus may include a first antenna having a first radiator and a first ground plane and a second antenna having a second radiator and a second ground plane. In some examples, a hybrid antenna may be formed through coupling of the hybrid antenna to components of the first antenna and the second antenna. The hybrid antenna may include a third radiator. In some examples, an electrical interface may be disposed between the first antenna and the second antenna. In this regard, the electrical interface may couple the first ground plane to the second ground plane to form the third radiator.

Abstract: A multi-zoned dichroic mirror for use in a liquid crystal projection system that is capable producing projected images having improved color uniformity including a dichroic mirror which is divided into at least two regions of a first and a second region, a first region on the dichroic mirror that is coated with a first dichroic coating which compensates for color variations caused by variations in the incident angles of the incident light beams in a positive manner, and a second region on the dichroic mirror coated with second dichroic coating which compensates for color variation caused by variations in the incident angles of the incident light beams in a negative manner.
