Antenna presence doesn't significantly impact USB Wi-Fi adapter performance.
Your current adapter is a compact USB drive the thickness of two peas. Adding an antenna might improve signal capture and boost stability or speed. Larger adapters without antennas are bigger but lack that extra reception help. The size difference could come from either a heatsink or more materials to absorb signals.
It varies; you can use tiny effective antennas or large ineffective ones. Size usually isn't a big factor.
Only the range matters. Size, form, and antenna type are less important.
Bigger antennas provide improved coverage, not necessarily faster data transfer, unless you're near the limits of the signal range the antenna can handle.
Previously I believed that longer antennas always provided greater coverage, but I discovered otherwise when replacing the compact antenna on my PCIe Wi-Fi card with a larger one, which resulted in weaker signals. So, keep this in mind. Regarding your USB, ensure you choose a quality one—my experience with USB Wi-Fi adapters has been mixed. Unless you’re not into gaming or reliability is a concern, stick to my suggestions and you should be okay. As for distance, don’t worry; USB Wi-Fi adapters can cover surprisingly far distances. Even my adapter without an antenna performed better than my PCIe card with one.
Well, it depends on the size and layout. A 2.4ghz/5ghz dual band antenna performs worse than a specialized 2.4ghz or 5ghz one. A directional antenna typically offers the longest range, but you must aim it toward the AP. Keep in mind that antenna orientation matters—if the AP uses a horizontal signal, place other antennas horizontally as well (the same applies to vertical). With a "stick" antenna, avoid pointing it directly at the AP since that area is a dead zone; transmission and reception are strongest on the sides.
