Internal Coupled-FED Antenna for GSM/UMTS/LTE Operation for Tablet Computer
Antennas for mobile handsets is generally required to have such characteristics as compactness, complete built-in mountability, multiband operation and environment isolation as well as broadband bandwidth and high efficiency. A coupled-fed shorted monopole with its feed structure as an effective radiator for eight-band LTE/WWAN operation in the laptop computer is designed. The radiating feed structure capacitively excites the shorted monopole. The feed structure mainly comprises a long feeding strip and a loop feed. The loop feed is formed at the front section of the feeding strip.
