Single Open-Slot Antenna for LTE/WWAN Smartphone Application

A single open-slot antenna for long term evolution (LTE)/ wireless wide area network (WWAN) operation is proposed for smartphone applications. To achieve dual-band operation, the narrow openslot is fed by a simple 50-Ω vertical feedline with two horizontally protruded feeding structures. To further...

Zusammenfassung:	A single open-slot antenna for long term evolution (LTE)/ wireless wide area network (WWAN) operation is proposed for smartphone applications. To achieve dual-band operation, the narrow openslot is fed by a simple 50-Ω vertical feedline with two horizontally protruded feeding structures. To further attain good impedance matching for these two operating bands, an L-shaped metallic plate is used. From the measured results, good antenna efficiencies of more than 40% are demonstrated across the LTE/WWAN operation in the 698-960 MHz and 1710-2690 MHz bands.
