A promising 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 mm 3 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 for practical applications. 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. © 2010 Wiley Periodicals, Inc.
