Abstract
A broadband compact antenna comprises an electric dipole or monopole coupled or connected in parallel to a slot antenna. The slot antenna is composed of a flat, square or rectangular conducting sheet with a slot having a variety of possible shapes including a bow-tie or rectangle. The slot is then fed at the center by a coaxial transmission line with its outer conductor bonded to the sheet. To obtain broadband characteristics and compactness, a dipole or monopole, formed using either wire, flat strips or shapes formed in sheets of metal, is located in close proximity to the center of the slot.
