Microwave antenna structure with intergral radome and rear cover
 A suspended line feed type planar antenna is arranged with a number of antenna elements formed on a film-shaped substrate, and the film-shaped substrate is sandwiched between a plastic radome and a plastic rear cover, a conductive surface is plated on the rear surface of the plastic radome at its portion except the portions opposing the antenna elements and/or a conductive surface is plated on the whole front surface of the rear cover. The conductive surfaces and the antenna elements constitute resonance type printed path radiators, whereby the planar antenna of the invention can be simplified in construction and reduced in cost, thickness and weight, and the planar antenna of the invention can be increased in productivity and reliability.
