2.4 GHz Cubical Quad Antenna – Introduction
The Cubic Quad antenna is a commonly homemade antenna in the range of about 150 odd MHz. Our little project was to design one of these for use in the 2.4GHz range for 802.11 wireless LANs. The reason these are seldomly used for 2.4GHz is the size.
The picture below is a 4 element cubic quad for the 147MHz range. Large isn’t it.
The one we are going to build for 2.4GHz will only be 6cm long!
