hi
i happen to open one of the latest mobile phones..nokia n81...in that i cudnt find any xternal antenna ..when i asked with my proffessors thay said the antanna is a part of the pcb fabrication....
a small rod like connection exist but due to surface aree the have good reception...and advanced filters usend in the circuit makes it almost impervious to atmospheric electromagnetic noise...

take care

Many examples of multi band mobile phone antennas (with exact dimensions) can be found in this book:
"Multiband Integrated Antennas for 4G Terminals" by David A. Sanchez-Hernandez (Editor)

HI

These days the most happening antenna in the mobile communications is PIFA along with microstrips and others.but PIFA has taken over the mobile communication market and extensive research is being carried out to bring in new improvements.
