Abstract:
novel design of at internal PIFA integrated with an
RF-shielding metal case for application in a clamshell or fielder-tvpe
mobile phone is presented. The integrated PIFA has a bent and tapered
radiating arm in order to easily fit in the casing of the clamshell mobile
phone as an internal antenna. The integrated PlEA can also provide a
wide operating bandwidth fir UM7S (1920-2170 MHz) operation. In
addition, for the clamshell mobile phone in either the talk or standby
condition, only a small effect on the operating bandwidth of the integrated
PIFA is obtained. The experimental results of the proposed design are presented
