A single-feedpoint multiband monopole antenna is provided with independent radiator elements. The antenna comprises a microstrip counterpoise coupler having a single-feedpoint interface, a first radiator interface, and a second radiator interface. A first microstrip radiator, i.e. a meander line microstrip, has an end connected to the counterpoise coupler first radiator interface, and an unterminated end. A second microstrip radiator, i.e. a straight-line microstrip, has an end connected to the counterpoise coupler second radiator interface, and an unterminated end. The two radiators are capable of resonating at non-harmonically related frequencies. As with the two microstrip radiators, the microstrip counterpoise coupler is a conductive trace formed overlying a sheet of dielectric material. The counterpoise coupler can come in a variety of shapes, so that the overall antenna may take on a number of form factors.
