Allowable Subject Matter Claim 10 is objected to as being dependent upon a rejected base claim but would be allowable if rewritten in independent form including all of the limitations of the base claim and any intervening claims. IDS document Fa et al. (CN 112751148B; “Fa”) discloses wherein the plurality of functional units comprise a phase shift circuit (p. 8, ¶1, “the two fixed transmission lines 14, the two movable transmission lines 21 and the transverse strip line 22 are coupled to form a phase-shifting transmission line together”). However, Fa does not teach, or suggest, wherein the feed network further comprises a phase shift medium; the phase shift medium covers the support frame; and the phase shift medium is capable of moving relative to the support frame under control of the phase shift circuit. IDS document Browne et al. (WO 2009/021550; “Browne”) discloses that the plurality of functional units comprise a phase shifting circuit (p.8, ¶3, a phase shifting device is electrically connected in the breaks 73 in the tracks 71 thereby providing the electrical connection between the radiating elements 10 and the feed “harness”). However, Browne does not teach, or suggest, wherein the feed network further comprises a phase shift medium; the phase shift medium covers the support frame; and the phase shift medium is capable of moving relative to the support frame under control of the phase shift circuit. IDS document Wang et al. (WO 2022/041621; “Wang”) discloses a phase shift medium (dielectric plates 21), wherein the plurality of functional units comprise a phase shift circuit (e.g. phase shifting conductor strip 22); and the phase shift medium is capable of moving relative to the support frame (p. 6, “the dielectric phase shifting unit 2 is provided with a phase shifting conductor strip 22 and a dielectric plate 21, the medium plate 21 moves along the lateral direction Y of the cavity 1”). Wang does not teach, or suggest, the phase shift medium covers the support frame, or that the phase shift medium is capable of moving under control of the phase shift circuit. Conclusion The prior art made of record and not relied upon is considered pertinent to applicant's disclosure: Yu (US 2024/0275042) – phase shifter with adjustable output mode has movable sliding plate sides. Liu (US 2017/0069941) – dielectric phase shifter comprising a cavity, and a dielectric element slidably mounted in the receiving space.
