Provided is an antenna where low transmission loss and visibility are simultaneously achieved. The antenna includes: a transparent film substrate; an antenna element that is provided on one surface among two surfaces of the transparent film substrate; and a ground part that is provided on the other surface among the two surfaces of the transparent film substrate. The antenna element and the ground part are formed of a mesh pattern formed of a fine silver wire, and a line width of the fine wire is 1.0 μm or more and less than 5.0 μm. A thickness of the transparent film substrate is 30 μm or more and 300 μm or less.

Monodirectional antennas may be arranged to radiate in a near omni-directional pattern. By incorporating switches into the antenna arrangement, the antennas can be controlled to selectively radiate from a common radiofrequency feed. These arrangements may be packaged in a housing, which may aid both in antenna performance and in antenna installation. According to another aspect of the disclosure, housings may include a plurality of antennas, and one or more procedures may be implemented to determine a codebook to radiate from the circular arrangement according to various beam constrains.

According to various aspects, exemplary embodiments are provided of antenna assemblies. In an exemplary embodiment, an antenna assembly generally includes at least one antenna element configured to be operable for receiving high definition television signals.

A method of installing an antenna array module on a window includes adhering the antenna array module to the window and connecting the antenna array module to an external module via a cable. The cable may extend from one side of the window to the other. The antenna array module may include a substrate (e.g., a transparent substrate) and a plurality of antenna elements (e.g., meshed patches) on one or more layers of the substrate. Beamformer(s) and splitter/combiner(s) operably connected to the plurality of antenna elements may be embodied in the external module or in the antenna array module (e.g., in whole or in part in one or more integrated circuits on a surface of the substrate). The external module may output digital data derived from mm-wave, intermediate frequency (IF) and/or baseband signal(s) received from the antenna array module.
