Antenna bandwidth optimization for gaming applications

The design of an aperture-coupled, dual polarized patch antenna on a small-size FR-4 substrate with a convenient tuning technique is proposed. This technique allows the antenna´s impedance bandwidth to be adjusted to fit the desired frequency application. This design is applied to a gaming console to establish a wireless link between a console and a controller. The use of FR-4 substrate allows the manufacturing costs related to mass circuit production to be significantly reduced. Although the size of the antenna is smaller than standard patch antennas operating at a desired frequency, the performance criteria such as gain, efficiency and broadside radiation are not compromised. The measured results show that a maximum bandwidth greater than 7% can be obtained.
