#DIY DOUBLE BIQUAD WIFI ANTENNA PATCH#
Posted in Radio Hacks Tagged antenna, microwave, patch antenna, RF Post navigation Meanwhile, if you are interested in microwave RF design, take a look at Michael Ossmann’s primer on the subject. It would be interesting to see the same antenna produced from a more consistent dielectric material than generic FR4. We can all learn something from ’s write-up, and we salute him for staying the course to get the design to a usable point. He ended up using an inset feed, with a co-axial cable emerging away from the edge of the patch, and was able to achieve a far better result. Simulation of the design also yielded a different resonance from the one calculated, and discussing it with others yielded the conclusion that the feed might be at fault. Further, it had a resonance at the required frequency but also unexpected ones at 3.7 and 4.6 GHz. When hooked up to a VNA its impedance was all wrong. This was produced on a PCB, a normal 1.6mm thick FR4 fiberglass board. The process started with a set of calculations to derive the patch dimensions and a bit of PCB work adding a stripline feed. His write-up is a fascinating tale of the challenges and pitfalls of creating something which is deceptively simple at first sight but which becomes significantly more complex as he characterizes his design made real as a PCB. Much heartache is to be saved by using an off-the-shelf design, and only the foolhardy venture willingly down the stripline into the underworld of complex microwave resonances.īut every would-be microwave designer has to start somewhere, and for that start came with a 2.4 GHz patch antenna. For more infomation on this kit including antenna comparision test results read my review of the wardrivingworld diy biquad kit.If a grizzled RF engineer who bears the soldering-iron scars of a thousand projects could offer any advice, it would be that microwave antennas are not a field to be entered into lightly. Fine but good want to see much in detail.Īnand on at 2 27 pm said. 22 thoughts on biquad and double biquad homemade wifi antenna.

And i want to make one biquad antenna for 5 8 ghz.īest diy indoor or outdoor tv antenna ever made. One of the biggest problems with this hobby is the antenna. Hence here is the double biquad antenna and biquad antenna calculators for handmade antenna based on average data. Biquad antennas can be built from common materials which is nice because you don t have to scrounge around for the perfectly sized soup can we did have to buy some. I have a small line of site path though some trees to the area i want to broadcast to. Parts list a single sided copper clad pcb sheet i found a 20x10cm sheet with an incom. The dbi scale is logarithmic in base 10 where 3 dbi is a doubling in gain. So i wanted to use a bi quad with a parabolic reflector. Biquad and double biquad antennas as well as diy kits for building your own antennas are also available from biquad supply. Now it is time to create the antenna i want to use. Omnidirectional biquad antenna for 5 8 ghz fpv duration. If you share the measurements i can easily build it. All wifi users are constantly wanting more powerful signals. This is basic instructions for handmade wifi 5 5 8 ghz 13 14dbi double biquad external antenna.
