Abstract

A design of dual-band balanced antenna structure operating in the 700 and 2600 MHz LTE bands is studied and investigated. The overall dimensions of the radiator are 50 x 18 × 7 mm3 allowing it to be easily concealed within mobile handsets. A broad-band balun is designed and integrated with the antenna handset in order to provide the feeding network and perform the measurements of the antenna radiation performance. Prototypes of the proposed antenna with and without balun are fabricated and verified. The simulated and practical results with and without the handheld effects in terms of reflection coefficient, power gain and radiation pattern, are studied and show reasonable agreement.
