PCB0048 Tree Antenna

PCB0048 Tree Antenna

This functional 10 cm “tile” sized tree shaped antenna works modestly from 1300 MHz to 18 GHz. It does not have very broadband return loss despite its complex top shape and multiple “branches”. The modest return loss performance does mean radiation efficiency is also modest across the operating range. 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 !

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.

Please remember – We can test your antenna project too! We have a full range of testing services listed HERE 

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.
