| 333237000 | Leaky lines | 6 |
| 20100001817 | LEAKY COAXIAL CABLE - Provided is a leaky coaxial cable in which a plurality of slots | 01-07-2010 |
| 20100194500 | LEAKY CABLE - A leaky cable with a central conductor, and an outer conductor having a rectangular cross section surrounding the central conductor. The outer conductor has a first and a second surface parallel to each other, and at least one slot row formed in at least one of the first and second surface. The slot row is formed in a first direction of the outer conductor and includes a plurality of slots each configured to form a leaky electromagnetic field. An insulator is disposed between the central conductor and the outer conductor. The width of the rectangular cross section in a direction parallel to the first and second surfaces is less than half of a wavelength of an electric signal transmitted through the leaky cable. | 08-05-2010 |
| 20110234338 | Bundled leaky transmission line, communication device, and communication system - A bundled leaky transmission line includes a transmission line inside which a signal is transmitted, wherein multiple leaky transmission lines which exchange a radio wave mainly via a slit provided on an outer circumference of the transmission line are bundled, and the leaky transmission lines are bundled together such that the slit which is provided to each of the leaky transmission lines and which gives radio wave directionality to the leaky transmission line is directed in a direction different from each other. | 09-29-2011 |
| 20140197907 | ELECTROMAGNETIC STRIPLINE TRANSMISSION LINE STRUCTURE - A transmission line structure includes a first transition element, a second transition element, and an active element. The first transition element has a radio frequency injection port and the second transition element, which is spaced from the first transition element, has a radio frequency termination port. An active element is in electrical communication with the first transition element and the second transition element. The active element includes a first and second connection region where the active element is attached to the first and second transition elements. The connection regions are configured to reduce reflection of electromagnetic energy. | 07-17-2014 |
| 20150091673 | LEAKY FEEDER ARRANGEMENT - A leaky co-axial cable arrangement, including a co-axial cable, a plurality of radiation slots arranged on the co-axial cable and an activation arrangement configured for affecting predetermined regions on the cable to selectively activate or deactivate at least one of the plurality of radiation slots to provide the leaky co-axial cable arrangement. | 04-02-2015 |
| 20160380327 | METHODS AND APPARATUS FOR INDUCING A NON-FUNDAMENTAL WAVE MODE ON A TRANSMISSION MEDIUM - Aspects of the subject disclosure may include, for example, a system for generating first electromagnetic waves and directing instances of the first electromagnetic waves to an interface of a transmission medium to induce propagation of second electromagnetic waves substantially having a non-fundamental wave mode. Other embodiments are disclosed. | 12-29-2016 |
