Abstract

Described herein are techniques related to one or more systems, apparatuses, methods, etc. for a wireless fidelity (Wi-Fi) based wireless docking station arrangement.

Claims

3-1. The docking station as recited in claim 1, wherein the antenna coupler includes an array of parallel microstrip lines that are input at the same location, wherein an electrical distance between the parallel microstrip lines is kept at an odd integer multiple of ninety degrees.

9. An antenna coupler comprising:

a microstrip conductor that conducts a signal current;

a ground plane that is configured as a return path for the signal current;

a dielectric material that is positioned in between the ground plane and the microstrip conductor, the dielectric material includes a thickness size that is lesser than a wavelength, the wavelength is defined by a frequency of the signal current.

10. The antenna coupler as recited in claim 9, wherein the microstrip conductor includes a width that is adjusted to increase or decrease a coupling coefficient when the microstrip conductor is positioned on top of another microstrip conductor during a wireless communication.

11. The antenna coupler as recited in claim 9, wherein the signal current in the microstrip conductor and the returning signal current through the ground plane are substantially close to each other.
