Abstract:

Systems and methods for providing antenna beams having reduced grating and side lobes when steered off of the antenna broadside are disclosed. According to the present invention an arrangement of antenna elements suitable for use in generating antenna beams steered at greater angles off of the antenna broadside is utilized with a beam feed network consistent with the antenna beams being steered at the greater angles and reduced antenna element spacing to provide the reduced grating and side lobes. A preferred embodiment utilizes a 2 Butler matrix coupled to 2 antenna columns spaced according to the present invention to provide 2 antenna beams. Preferred embodiments provide a dual mode antenna system in which antenna elements of a first mode are interspersed with antenna elements of a second mode.

Abstract:

A door protector used for protecting an area on a door from marring caused by the scratching of dogs. A protective pad is provided with a scratching surface. The scratching surface has a texture such that as a dog scratches thereon with its paw an audible sound is generated. The sound alerts the dog's owner that the dog desires to pass through the door. The protective pad is adhered to the surface of the door so that when the dog scratches on the protective pad the sound of the scratching is transmitted to the door so the dog owner is alerted that the dog is at the door. The protective pad is at least translucent, or even somewhat transparent, so that the color and texture of the door surface shows through the protective pad. The door protector is aesthetically pleasing to the dog's owner and satisfies the dog's desire to scratch on the door and functions to alert the dog's owner of the scratching.
