Patent number: 10854959Abstract: A telecommunications antenna comprising a plurality of unit cells each including at least one radiator which transmits RF energy within a bandwidth range which is a multiple of another radiator. The radiators are proximal to each other such that a resonant condition may be induced into the at least one radiator upon activation of the other radiator. At least one of the radiators is segmented into capacitively-connected radiator elements to suppress a resonance response therein upon activation of the other of the radiator.Type: GrantFiled: March 2, 2018Date of Patent: December 1, 2020Assignee: John Mezzalingua Associates, LLCInventors: Taehee Jang, Niranjan Sundararajan, Lance D.

Publication number: 20200169002Abstract: Disclosed is a telecommunications antenna having a plurality of cloaked low band (LB) and high band (HB) dipoles. The LB and HB dipoles provide cloaking by breaking the dipoles into dipole segments, and providing conductive cloaking elements over the gaps between dipole segments to form a plurality of capacitors along the dipole. The capacitors along the LB dipoles provide a low impedance to LB RF signals and a high impedance to HB signals. The capacitors formed on the HB dipoles provide a low impedance to RF signals and high impedance to harmonics of the LB RF signals. This cross-cloaking of dipoles enables more dense arrangements of LB and HB dipoles on an antenna array face, providing opportunities to arrange, for example, the LB dipoles with an array factor that results in an advantageous fast roll off gain pattern.Type: ApplicationFiled: May 17, 2018Publication date: May 28, 2020Applicant: John Mezzalingua Associates, LLCInventors: Alex Waldauer, Charles Buondelmonte, Taehee Jang, Niranjan Sundararajan

Modular unit cell construction for a high performance, low profile (HPLP) telecommunications antenna
Patent number: 10320092Abstract: A unit cell for an antenna comprises a conductive ground plane, a low-band radiator, a pair of high-band radiators, and a conductive partition disposed along an edge intersecting a pitch axis of the conductive ground plane. The low-band radiator comprises a pair of orthogonally coupled dipoles each having a vertical stem portion and an arm portion. Each arm disposed in a plane orthogonal to the conductive ground plane. The arm portions, collectively and on-edge, produce an L-shaped radiator parallel to the conductive ground plane. Each of the high band radiators comprises a pair of cruciform radiators, each cruciform electrically connected to, spaced-apart from, and parallel to the conductive ground plane. The conductive partition isolates at least a portion of the RF energy transmitted by the low and high-band radiators.Type: GrantFiled: July 31, 2017Date of Patent: June 11, 2019Assignee: John Mezzalingua Associates, LLCInventors: Kevin T.

Publication number: 20190019593Abstract: Optically transparent, highly conductive conductor materials are provided, which in certain variations may also be flexible. Methods of making transparent conductive conductors, such as electrodes, are also provided. Such a method may include creating a groove pattern on a substrate that defines a two-dimensional array. Then an electrically conductive material may be selectively applied within the groove pattern of the substrate so as to create a transparent conductor (e.g., a transparent conductive electrode (TCE)). The transparent conductor has a sheet resistance of ?about 5 Ohms/Square and a transmissivity of ?about 50% for a predetermined range of target wavelengths of electromagnetic energy. Such methods may form linear micromesh conductive arrays and tortuous micromesh conductive arrays that can be used in a variety of optoelectronic applications, including as optically transparent, flexible and mechanically reconfigurable zeroth-order resonant (ZOR) antennas.Type: ApplicationFiled: December 28, 2016Publication date: January 17, 2019Applicant: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Lingjie Jay GUO, Taehee JANG, Sangeon LEE, Jinhwan LEE
