Abstract
A reflector 1 comprises a body 2 with an electromagnetic radiation reflective surface 3 and support means5, 6; where the reflector 1 is able to be positioned to direct electromagnetic radiation in a desired direction. The reflector body 2 may have a curved elliptical shape with a parabolic surface. The reflective surface 3 may be formed of aluminium foil. The aluminium foil may include a self-adhesive layer which is used to secure the foil to the surface of the reflector body 2. The reflector 1 may include a pair of tabs 5, 6; each of which are located on opposite sides on an axis of symmetry of the reflector 1 and include an aperture 7, 8 to receive an elongate aerial B of a router A. The tabs 5, 6 may extend in a direction away from the reflector and may be flexed such that the aperture 7, 8 in each tab aligns with the aerial B. Flexible fingers 7A, 8A may be located in the apertures 7, 8 to provide frictional engagement between the aperture 7, 8 and the aerial B. The reflector arrangement may include a stand to position a reflector body adjacent to a router A.
Description
1
Title: Router Reflector
The present invention relates to a router reflector, especially for a WiFi router.
Many computers connect to the internet through a WiFi router. The WiFi router usually has an aerial which transmits and receives information to and from a computer. The transmitted electromagnetic energy is transmitted in all directions from the router aerial. If however the router is at one end of a building and the computer users wishing to connect to the router are in a specific area in the building, only a small proportion of the total energy transmitted wil l be receivable by a computer. This reduces the internet speed.
The invention seeks to provide a solution to this problem.
According to the present invention there is provided a router reflector comprising a reflector body having a reflective surface to reflect electromagnetic radiation, and support means to support the reflector body adjacent a router transmitter, said reflector body being positionable to direct electromagnetic radiation in a desired direction.
Preferably the reflective surface is a parabolic surface.
Preferably the reflector body is a curved elliptical shape.
2
Preferably the reflective surface is formed from aluminium foil. The aluminium foil may have a self-adhesive face to secure it to the reflector body.
In one embodiment the reflector body has a pair of tabs on opposing sides of the reflector body each with an aperture to receive an elongate aerial of a router. Preferably the tabs are positioned on or adjacent an axis of symmetry of the reflector surface. Preferably the tabs normally lie in a first position extending away from each other either side of the reflector body but can be flexed to second position projecting forward of the reflective surface with the apertures in an axial alignment to receive an elongate aerial. Preferably the apertures include flexible fingers to provide a friction surface to engage a router aerial.
The router body may include a stand to position the reflector body adjacent a router.
An embodiment of the invention will now be described with reference to the accompany ing drawings in which:
Figure 1 shows a perspective view of a router reflector, and
Figure 2 shows the router reflector of Figure 1 connected to a router aerial.
Referring to Figures 1 and 2 there is shown a router reflector 1 according to the invention, and a WiFi router A with an aerial B of a type well know in the art ,
3
Reflector I has a reflector body 2 formed as a plastics moulding as a curved elliptical shape with an axis of symmetry X-X. Reflective body 2 has a parabolic reflective surface 3 to reflect electromagnetic radiation. Surface 3 includes an aluminium foil layer 4 which may be bonded to the body 2 by a self adhesive layer on the back of the foil layer (not visible).
A pair of Z-shaped plastic tabs 5,6 are provided on opposing sides of the reflector body 2 each with an aperture 7,8 respectively to receive an elongate aerial of a router (see Figure 2). The tabs 5,6 are positioned on the axis of symmetry X-X of the reflector surface, and may be secured to the reflector body by means of rivets 5A,6A. Tab apertures 7,8 support radially spaced flexible fingers 7A,8A to provide a friction surface to engage router aerial B (see Figure 2).
The tabs 5,6 normally lie in a first position extending away from each other either side of the reflector body (see Figure 1) but can be flexed to second position (see Figure 2) projecting forward of the reflective surface 3 with the apertures 7,8 in an axial alignment to receive elongate aerial B. Tabs 5,6 provide support means to support the reflector body adjacent a router transmitter.
4
In use the reflector can be turned around the aerial B to reflect and direct electromagnetic radiation in desired direction, e.g. an area in a building. Furthermore, electromagnetic radiation from a computer WiFi aerial communicating with the router A will be focused onto the aerial B due to the parabolic shape of the reflective surface. This results in improved signal strength and hence internet speed.
Some WiFi routers do not have an aerial of the type show in Figure 1 or an external aerial at all. It is envisaged that a reflector body may include a stand (not shown) as a support means to position the reflector body adjacent a router. The stand may be instead of or in addition to the tabs 5,6.
The invention may take a form different to that specifically described above.
Further modifications will be apparent to those ski l led in the art without departing from the scope of the present invention.
