Question 129
Correct Answer: B
The radiation patterns presented in the exhibit correspond to a patch antenna. Patch antennas typically exhibit a directional radiation pattern which is evident in both the azimuth and elevation plane patterns shown. The azimuth pattern resembles a broad circle, indicating a broad directional range, while the elevation pattern shows more distinct lobes, typical of a patch antenna's higher directionality. This is characteristic of patch antennas, which are designed to provide higher directed gain for specific coverage areas.

Patch Antenna, the same diagram from Cisco Whitepaper. (Figure 7. Single Patch Antenna with 3D Radiation Pattern, Azimuth Plane Pattern and Elevation Plane Pattern) https://www.cisco.com/c/en/us/products/collateral/wireless/aironet-antennas-accessories/prod_white_paper0900aecd806a1a3e.html

You can see on this https://www.cisco.com/c/en/us/td/docs/routers/connectedgrid/antennas/installing-combined/b-cisco-industrial-routers-and-industrial-wireless-access-points-antenna-guide/m-ant-wpan-y-out-n.html
TheNetworkStudentOption: B
According to the whitepaper in the reference, B is correct. Fun fact is that according to the official exam guide it should be a Yagi, but apparantly they mixed up the pictures in the guide which makes it confusing.

Classic Cisco...the "offical" study books are trash.

Nothing seems to be mixed up in my encor book.. Page 535 mentions Figure 18-23 which is on page 536. You can compare it to the patch antenna patterns from Figure 18-20 (535)

Book shows nearly same pattern style in azimuth and elevation for patch and yagi, with patch being more oval with minimal tail. In this test question, they seem to be mixing pattern style. Yagi also seemed plausible Then again, Yagi pattern seems more narrow focused.
