A wiring board includes: a substrate having transparency; a plurality of first wirings which are arranged on an upper surface of the substrate and extend in a first direction and each of which has a back surface in contact with the substrate and a front surface facing an opposite side of the back surface; and has a back surface in contact with the substrate and a front surface facing an opposite side of the back surface. The first wiring has a pair of side surfaces which extend in the first direction and are adjacent to the back surface of the first wiring, and each of the pair of side surfaces of the second wiring is recessed inward. The second wiring has a pair of side surfaces which extend in the second direction and are adjacent to the back surface of the second wiring.

An antenna array includes a first patch antenna and a second patch antenna which are oriented mutually in parallel. Each patch antenna includes a linear array of radiation elements. Adjacent radiation elements within each patch antenna are equidistantly spaced apart and are interconnected. In addition, a connecting line between adjacent first ends of the two patch antennas is provided, and the two second ends of the patch antennas are each adapted for transfer of an electrical oscillation. The spacings between the adjacent radiation elements of the first patch antenna are greater than the spacings between the adjacent radiation elements of the second patch antenna.

Conventionally, an image forming apparatus including a plurality of antennas for detecting for an arrival direction of a radio wave was not invented. In the present invention, a communication board including a plurality of antennas for wireless communicating with a communication terminal is provided on a front side with respect to a front-rear direction of an image forming apparatus including an imager forming unit in a vertical direction.

An optimal arrangement for a configurable smart antenna in a wireless (e.g., Wi-Fi) network having zero, one, or more other mesh nodes is determined by characterizing the network performance for each possible arrangement by determining a number of connected devices (e.g., either client devices or mesh nodes) and one or more other performance parameters. If one arrangement has more connected devices than any other, then that arrangement is selected. If two or more arrangements have the same greatest number of connected devices, then one or more other performance parameters are applied either serially or in parallel to select the optimal arrangement. In some implementations, the other performance parameters are sums or averages for all connected devices. In other implementations, the other performance parameters are for only a selected priority device, where the selected arrangement must connect to the priority device.

An antenna is made from strips of a shape-memory alloy or other resilient material acting as a spring with attached branches that constitute individual monopole antennas. In the folded state, the antenna looks like a strip roll and can be placed on a satellite. When in orbit, the antenna unfolds after the roll retention mechanism is released and orderly unfolds unrolling from a support frame or otherwise extends. The proposed design of monopole branches utilizes conductors of minimum length and achieves maximum directivity. Each monopole branch is connected to the signal receiver/transmitter by signal conduit elements. A system may include at least two such unfolding antennas thus achieving even greater operational effectiveness in regard to signal steerability, interference suppression and reduced moment of the satellite inertia. To prevent problems, additional measures are used that prevent unwinding of inner layers of the roll before the outer layer is extended.
