The TetraAnt 15.5 GHz Wideband antenna was originally designed as the unmanned aerial vehicles (UAVs) noise radar antenna. The important feature is a small size compared to the credit card, a durable construction, low mass and a isolation about 40 dB.
Despite the mutual coupling is about -38 dB, the antenna shows a good broadband performance. It operates in the 14.5–16.5 GHz range, with a center frequency of 15.5 GHz.

TetraAnt 15.5 GHz Wideband - Coupling
- The coupling between ports of the antenna TetraAnt 15.5 GHz High Isolation version.
- For the frequency range 14.5 - 16.5 [GHz] the isolation is no less than 38 dB
- Measurement-based data
TetraAnt 15.5 GHz Wideband - Gain
- The antenna's gain was measured in the Far-Field range in a low scatter environment, with two-antenna method.
- This is realized gain measured on the antenna's connector. All losses are taken into account.
- Realized gain is the actual power gain of an antenna that includes both internal material losses and reflection losses caused by impedance mismatch at the input port.
TetraAnt 15.5 Wideband - Radiation Patterns in the Polar Form
Radiation patterns are presented for the following frequency points: 14.5 - 15.5 - 16.5 GHz
If some component is invisible, it means that has lower value than -40 dB. So it is out of the scale. Patterns are referenced to 0 dB, the full scale is 40 dB.
- H polarization plane, co-polar: GREEN
- H polarization plane, cross-polar: BLACK (out of scale, below -40dB)
- E polarization plane, co-polar: RED
- E polarization plane, cross-polar: BLUE
E - electric, H - magnetic
