Office Action

§102
Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Information Disclosure Statement The information disclosure statement (IDS) submitted on February 20, 2024 is in compliance with the provisions of 37 CFR 1.97. Accordingly, the information disclosure statement is being considered by the examiner. Election/Restrictions The amendments filed March 9, 2026 overcome the showing of distinct inventions between the inventions corresponding to groups I and II. Accordingly, the restriction requirement filed February 13, 2026 is hereby withdrawn. Claim Rejections - 35 USC § 102 The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention. Claims 1-3, 5-10, 12-21 and 35 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by SEMILOVSKY (U.S. Publication No. 2023/0163468). SEMILOVSKY, in figure 1a, discloses: Claim 1: A base station antenna (100), comprising: a first radio frequency ("RF") port; a first array of radiating elements (102) that are configured to transmit and receive RF signals in a first operating frequency band, where each of the radiating elements in the first array is coupled to the first RF port; a second RF port; and a second array of radiating elements (101) that are configured to transmit and receive RF signals in a second operating frequency band, where each of the radiating elements in the second array is coupled to the second RF port, and the second operating frequency band is at higher frequencies than the first operating frequency band, wherein a first of the radiating elements in the first array includes a first dipole radiator that has a center-fed first dipole arm that comprises a first conductor (103), where at least a first portion of the first conductor has a helix-shape (fig. 1a). Claim 2: wherein the first portion of the first conductor comprises at least two resonant circuits that, together or in combination with additional resonant circuits, are configured to suppress formation of currents in the second operating frequency band on the first dipole arm (¶[0034]-[0035]). Claim 3: wherein a diameter or electrical length of the first portion of the first conductor or a magnitude or spacing of turns of the helix defined by the first portion of the first conductor is selected to suppress formation of currents in the second operating frequency band on the first dipole arm on the first dipole arm (¶[0034]-[0035], fig. 2b). Claim 5: wherein the first dipole arm further comprises a second conductor, wherein at least a first portion of the second conductor has a helix-shape, and wherein the first portions of the first and second conductors are wound around a common axis (¶[0034]). Claim 6: wherein the first conductor further includes a second portion that has a helix-shape (¶[0034]-[0035]). Claim 7: wherein the first portion is collinear with the second portion and spaced apart from the second portion by a third portion of the first conductor that does not have a helix-shape (¶[0034]). Claim 8: wherein the first portion extends at an oblique angle with respect to the second portion (fig. 6a). Claim 9: wherein the first conductor forms a conductive loop (fig. 6a). Claim 10: wherein the first portion of the first conductor and one or more additional portions of the first conductor that are part of the conductive loop each have a helix-shape (fig. 6a). Claim 12: wherein the first dipole radiator further includes a center-fed second dipole arm that comprises a second conductor, where at least a first portion of the second conductor has a helix-shape (fig. 1a). Claim 13: A base station antenna (100), comprising: a first radio frequency ("RF") port; a first array of radiating elements (102) that are configured to transmit and receive RF signals in a first operating frequency band, where each of the radiating elements in the first array is coupled to the first RF port; a second RF port; and a second array of radiating elements (101) that are configured to transmit and receive RF signals in a second operating frequency band, where each of the radiating elements in the second array is coupled to the second RF port, and the second operating frequency band is at higher frequencies than the first operating frequency band, wherein at least some of the radiating elements in the first array of radiating elements comprise: a first dipole radiator that comprises a first dipole arm and a second dipole arm (fig. 6a); and a second dipole radiator that comprises a third dipole arm and a fourth dipole arm (fig. 6a), wherein the first through fourth dipole arms comprise respective first through fourth conductors, where each of the first through fourth conductors includes at least a first portion that has a helix-shape (fig. 6a). Claim 14: wherein the first dipole radiator is a center fed dipole radiator and the second dipole radiator is a center fed dipole radiator (fig. 1a). Claim 15: wherein each of the first through fourth dipole arms is configured to suppress formation of currents on the respective first through fourth dipole arms in a predetermined frequency range (¶[0034]-[0035]). Claim 16: wherein an electrical length of each of the first through fourth dipole arms is approximately one quarter of a wavelength that corresponds to a center frequency of an operating frequency band of the cross-dipole radiating element (fig. 1a shows half wavelength dipoles). Claim 17: wherein the first dipole arm further comprises a second conductor, and wherein the first portion of the first conductor and a first portion of the second conductor that has a helix- shape are wound around a common axis (¶[0034]). Claim 18: wherein each of the first through fourth conductors further includes a second portion that has a helix-shape (¶[0034]). Claim 19: wherein the first portion of each of the first through fourth conductors is collinear with the second portion of each of the respective first through fourth conductors and spaced apart from the respective second portion by a respective third portion of the first through fourth conductors that does not have a helix-shape (¶[0034]). Claim 20: wherein the first portion of each of the first through fourth conductors extends at an oblique angle with respect to the second portion of each of the respective first through fourth conductors (fig. 6a). Claim 21: wherein the first through fourth conductors each form a respective conductive loop (fig. 6a). Claim 35: wherein the first portion of the first conductor and one or more additional portions of the first conductor that are part of the conductive loop each have a helix-shape (fig. 6a).
