Abstract
An antenna for use in a distributed antenna system includes: (a) a feeding circuit on a first side of a first dielectric defining a planar edge perpendicular to the first side, a coplanar waveguide comprising a signal feed and a signal return coplanar with and interfittingly apart from the signal feed; (b) a radiator circuit on a second side of a second dielectric, a monopole radiator and a radiator return being copolanar and spaced apart from each other, the first dielectric capacitively coupling the signal feed to the monopole radiator; and (c) an edge connection along the planar edge for electrically connecting the signal return to the radiator return. A cover encloses the feeding circuit, including its impedance matching, in a water-resistant enclosure. The antenna ceiling-mounts indoors, is coated with a fire-resistant coating, and is operable at VHF (132-174 MHz), UHF (350-520 MHz), and 698-960 MHz.
