I didnt find much on the theory behind them. I did find one article that stated the reflector should be about .3 wavelegnth behind the antenna. I was hoping to see how diff reflector types and sizes would affect the coverage patern of the antenna.
If you dont mind please let me pose another question. Should i choose a vertical 1/4 wave and wanted to put some type of reflector behind it to increase gain and focus horizontal beamwidth how do i properly calculate a solid metal or screen reflector? Is there a basic formula for this? Does it...
Pay attention to polarity (H vs V). There can be a big (20-30dB) cross pol. loss if you not matched.
Can you elaborate on this? Also, can you all recommend any good books on microwave antennae , delay lines etc?
So do i need a feed for the antenna or just solder each 1/4 piece of wire to the center conductor of the conector to make a small T ? I will definitly throw in the ground plain wires on each corner. This is for in home use but I have been VERY impressed with this antenna the problem is its on a...
i took pics of the antenna i am trying to mimic. It looks like a horizontal dipole with two 1/4 wave elements and i suppose there is some type of balun feeding them. Is there an easy way to mimic this design with a so-239 and some wire?
The pictures are at...
I am wanting to build a few general pupose antennas for 802.11 and ham experimentation in the 2.4 ghz band. I was going to build a simple antenna out of a chassis rf connector, one radiator on each corner and a 1/4 verticle attached to the pin in the center of the connector. However I have seen...
