A substantially planar antenna configured for easy installation in a ceiling or ceiling tile. The antenna is configured for duplex communications in carrier frequency ranges spanning at least a 2:1 ratio of frequency values from the highest to the lowest frequency in the carrier frequency band, such as the frequency range from 800 to 960 MHz and 1700 to 2400 MHz, and within a coverage pattern below the ceiling extending through 360&#xb0; azimuth and 180&#xb0; elevation. The antennas are manufactured as a printed circuit board that snaps apart into a number of panels, which each contains at least a planar antenna element and a cross brace that are used to assemble the antenna. The printed circuit board is a dielectric substrate carrying printed conductor including a radiating circular monopole disc radiating element, associated transmission signal paths, and printed indicia that typically include assembly instructions and a logo. The printed circuit board sheet configuration makes the antennas inexpensive to mass produce and easy to snap apart into individual units, which are themselves self-contained, easy to snap apart and install.
