摘要: A planar antenna for circular polarized microwaves incorporates a substrate sandwiched between conductive layers having a plurality of openings arranged in a rectangular array, with a pair of perpendicular excitation probes supported on the substrate in alignment with each opening, and a feed circuit for interconnecting the excitation probes in a predetermined phase relationship. Two additional conductive elements may be supported on the substrate in alignment with the excitation probes to provide improved impedance matching. The feed circuit may incorporate a pair of quarter wavelength feed lines connected to the excitation probes, with a resistance element interconnected between the feed lines. The feed point of the antenna may be located near the center of the array, occupying a position normally occupied by one of the pairs of excitation probes.

摘要: 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.

摘要: A deodorant equipment for an air conditioner includes a heater. A fin covers at least a part of an effective heating area of a surface of the heater. The fin has a radiator portion extending along a longitudinal direction of the heater. A vitreous coating film covers at least a part of an outer surface of the fin. A catalyst layer includes an absorption member and a catalyst. The absorption member absorbs odor components of air. The absorption member releases the odor components when being heated. The catalyst oxidizes and decomposes odor components when being heated.
