i think the antenna u made, is the same as the theory of the half wavelength dipole antenna., but wait, i think the impedance of the transmission line or the wire, is not match into the impedance of the improvise dipole antenna., and it is considered also the length of the improvise antenna., that's why, it should be computed, to be more enhance. nice!!

Perhaps useful back in '07. I haven't seen external antenna connectors on new phones in years. The 1900MHz spec of the antenna seems a bit specific for just one carrier but no mention is made about that. My frequency memory is a bit rusty but I'm pretty sure my phone is a quad band GSM phone which suggests there are, well, 4 bands. Not sure 1900 is one of them.
Now if only we could get these antenna connectors back on our phones.

OK, So I built the danged thang. Now I get to 03:50 mins into the video where Mike shows where I'm supossed to stick the antenna bit into my phone.
Eh-Oh! My Nokia N96 no have no antenna connection. My NOKIA E50 no have one ither, nor do my 6230. Oh! But wait! I still have my 6310i! Yes it have one connection, but no... I bought the new phone because the old phone no work no more.
Oh well, nice video, little practical value.
