Hi All,
I am looking for a good reference
book, any application notes or web links on how
to design a omnidirectional 2.4GHz PCB antenna.
I need to design a single board solution that
includes the antenna + all the other parts (RF chipset,
crystal, passive parts etc...).
I am looking
for realistic examples, I don't have time to loose
with complicated math theory or "never ending explanations".
:)
I learned these theories back in the 90's
when I was a university student but I forgot all
that stuff, I have been involved only in digital
designs since that time :)
I am looking for
an "Antenna CookBook", for something that can be
put in production, fast.
Thanking you in
advance,
MC

Hi MC I came across this PCB no-frills design
for 4.5GHz, but all dimensions are given as wavelength
fractions, so it could easily be scaled to 2.45G
or anyplace else in the spectrum. It is not
fully omni directional, being a double stack panel,
but a 2 way splitter/combiner with 2 of these back
to back should work. The reference is (UK)
IEE Proc. Microwaves, Antennas & Propagation
Vol. 146 No 4 Aug 1999. It comprises 2 parasitic
rectangular patches supported on low k foam, proximity
coupled to a 50 microstrip line that has a step
rise beneath the lower rectangle. The gain is about
7dBi, the FBR around 20dB, the cross-polar boresight
level is around 25dB, but the most spectacular parameter
for a patch antenna is the VSWR bandwidth: 58% for
a VSWR of 2:1 or better. Beat that
