PCB0046 Fractal Antenna

PCB0046 Fractal Antenna

This functional 10 cm “tile” sized fractal triangle pattern antenna works modestly from 1300 MHz to 18 GHz. It does not have the ultra broadband return loss promised in fractal designs, and this implementation has anti -resonances (high VSWR) around 3, 5, 9.5, and 11.5 GHz. Consequently, the average gain and efficiency also display shortcomings at these frequencies. It has sideways gain averaging about 2 dBi as expected from a monopole topology. It has peak gain (meaning it radiates in some direction) that is quite broadband, covering the entire 14:1 frequency test range, which is noteworthy !

This antenna is fed by a standard “5-pin” PCB mounted right-angle SMA jack, oriented away from the back of the antenna as shown.

A full Excel spreadsheet 3D gain results report can be downloaded HERE. This extensive test program covers full 3D spherical gain patterns at 1671 stepped frequencies from 1300 MHz to 18 GHz in 10 MHz steps. The test report details higher level performance data, such as: Forward Gain, Peak Gain, Radiation Efficiency, and VSWR/Return-Loss vs Frequency.

The full set of 1671 spherical plot-files can be downloaded HERE in “zipped” format. Unzip and use this plot-file along with our downloadable 3D plotting software HERE. Then create rotate-able/scale-able 3D plots on your own desktop at any test frequency.

We hope you enjoy your sample antenna. We do not offer antenna design services here so that we may focus customer design confidentiality. These “biz card” antennas are just for fun, and they are not for sale.
