Description

Window antenna Information about the divisional application The scheme is a divisional application. The original application (first filed application) of the division is an invention patent application with the application date of 2015, 11, 24, the application number of 201580070207.9 and the name of window antenna. The applicant has filed an invention patent application with the application number 201911227990.1 and the name of "window antenna" for the above-mentioned original application. However, the first review of the opinion notice for application number 201911227990.1 indicates that there is a singleness defect, and accordingly, the applicant filed the present divisional application. Cross Reference to Related Applications The present application claims the benefit of U.S. provisional patent application No.62/084,502, filed on 25.11.2014, entitled "Window Antenna," which is incorporated herein by reference in its entirety and for all purposes. Technical Field The present disclosure relates generally to electrochromic devices that may be used in electrochromic windows of buildings or other structures. Background Electrochromic is a phenomenon in which a material exhibits reversible electrochemically-mediated changes in one or more optical properties when excited into different electronic states. Electrochromic materials and devices made from them may be incorporated into windows for home, commercial, or other uses, for example. The color, transmittance, absorbance or reflectance of such electrochromic windows may be changed by inducing a change in the electrochromic material, for example by applying a voltage across the electrochromic material. This capability may allow control of the intensity of light of various wavelengths that may pass through the window. For example, a first voltage applied to an electrochromic device of a window may cause the window to darken, while a second voltage may cause the window to lighten. Electrochromic devices, such as most controllable light-switchable devices, contain electrical connections for controlling the application of electrical stimuli (e.g., in the form of controlled applied voltages and/or currents) to drive optical transitions and/or maintain optical states. Electrochromic devices are often implemented as very thin layers covering a surface, such as a face of a window surface. Such devices typically comprise a transparent conductor, typically in the form of one or more layers covering the electrochromic electrode and distributing the applied voltage over the face of the device to achieve complete and efficient light transmission. SUMMARY One aspect of the present disclosure relates to a window antenna characterized by (a) a window having one or more patches (lites) each including at least two surfaces having an area configured for viewing through the window, (b) an electrochromic device disposed on a first surface of the window, (c) an antenna structure disposed on either the first surface or a second surface of the window, and (d) a ground plane disposed on either the first surface of the window, the second surface of the window, the third surface of the window, or a structure connected to the window. In certain embodiments, the sheet has a length or width of at least about 60 inches. In certain embodiments, the electrochromic device does not have an ion conductor deposited between the electrochromic layer and the counter electrode layer. The antenna structure may have various configurations such as a strip line or a patch. In some embodiments, a stripline or patch structure may be used as part of a monopole antenna. In one such embodiment, the stripline has an axis along its length and the ground plane is substantially perpendicular to the axis of the stripline. Such a ground plane is provided on the same surface as the antenna structure or on a structure connected to the window. In certain embodiments, the stripline has an axis along its length and the ground plane is substantially parallel to the axis of the stripline. The ground plane may be provided on a different plane than the strip line, for example, on a different surface of the window pane. In certain embodiments, the antenna structure comprises two striplines, wherein the striplines are configured as dipole antennas. In some embodiments, the two striplines are substantially parallel. All references to a stripline may be replaced with references to a patch unless otherwise indicated herein. In certain embodiments, the antenna structure comprises a fractal structure. In one example, the fractal structure is disposed on a plane, and wherein the ground plane is substantially perpendicular to the plane of the fractal structure. In some such examples, the ground plane is disposed on the same surface as the antenna structure. In some such examples, the ground plane is disposed on a structure connected to the window. In some embodiments, the fractal structure is disposed on a plane, and the ground pla
