This functional 10 cm “tile” sized Yin-Yang symbol antenna works modestly from 1300 MHz to 18 GHz. It does not have very broadband return loss despite its complex shape. This antenna has low return loss from 2 to 4 GHz, with correspondingly high radiation efficiency at these frequencies. It has peak gain (meaning it radiates in some direction) that is quite broadband, covering the entire 14:1 test frequency test range, which is noteworthy !
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.

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.
