Abstract :
A multiband coupled on-board printed handset antenna capable of providing wideband operation for GSM 1800/1900, UMTS and LTE 2300/2500 is presented. Antenna consists of coupling monopole resonators which are extended from the feed and main ground plan to accommodate integration with circuit board of mobile handset. Antenna can easily be fabricated with the help of extended line and ground without disturbing main circuit board of handset, considering the presence of protruded components over circuit board. The antenna design uses fork-shaped monopole coupling resonators extended from active element and ground plane. These resonators along with prolonged length from patch and ground, as a function of resonating wavelength, control the bandwidth of antenna. Monopoles driven from patch and ground contribute the lowest and higher order resonant modes to form three wide operating bands centered at about 1800, 2500 and 5200MHz to cover GSM1800/1900/UMTS/LTE2300/2500. The results of this study confirmed that extended planner monopoles couple to form lower and higher resonant modes. This study provides new understanding on coupling monopole resonators and their application in handset antenna designing.
