Low-profile printed monopole antenna for penta-band operation in the mobile phone

A printed monopole antenna for penta-band operation in the mobile phone is proposed and studied. The antenna has a uni-planar structure and can be easily printed on an inexpensive FR4 substrate with a low cost. The antenna occupies a small area of 45 x 100 mm , yet it can generate two wide bands centered at about 900 and 2000 MHz to cover AMPS/GSM/DCS/PCS/UMTS operation. Good radiation characteristics of the antenna over the operating bands is observed. The proposed antenna is very promising for application in the mobile phone as an internal antenna for penta-band operation.
