Hi Ping-Ke,

After installing that Windows driver, the driver will be placed at C:\Program Files\D-Link\AN3U\Driver.

According to the line 266 of the C:\Program Files\D-Link\AN3U\Driver\WIN10X64\netrtwlanu.inf file [1], we know that this dongle uses a 8192FU chip.
The specification [2] which says it supports both WPA2 and WPA3 is also a clue. As far as I know, among all Windows drivers for Realtek 802.11n 2T2R chips, only the driver for 8192FU supports both WPA2/WPA3, others support WPA2 only.
This is how I determine what chip this dongle uses, but unfortunately there is no related report at linux-hardware.org [3] so cannot confirm it does use the ID 2001:3328.

[1] line 265 ~ 266 of the netrtwlanu.inf file
;; For 8192F DLINK
%DLink_AN3U.DeviceDesc% 			= RTL8192fu.ndi, 	USB\VID_2001&PID_3328

[3] Reports about the ID 2001:3328 and 2001:3329
