Abstract :
An internal laptop computer antenna capable of generating two wide operating bands to respectively cover the LTE700/GSM850/900 (698~960 MHz) and GSM1800/1900/ UMTS/LTE2300/2500 (1710~2690 MHz) operation is presented. The antenna occupies a size of 85 × 10 × 4 mm3 along the top edge of the supporting metal frame of the display panel and is suitable to be embedded inside the casing of the laptop computer. The antenna is a printed loop/monopole combo antenna formed by combining a quarter-wavelength printed loop with an internal matching circuit and a printed monopole with an internal distributed inductor. The proposed combo antenna leads to reduced size yet wide bandwidth to cover the eight-band LTE/GSM/UMTS operation.
