Popis:	This letter proposes a small-size printed antenna with multiband WWAN/LTE operation in a mobile phone by introducing a novel loop parasitic shorted strip and a C-shaped ground plane. The obtained impedance bandwidths across LTE and WWAN operating bands approach 277 and 1176 MHz, respectively. The proposed printed monopole antenna reduces the antenna size by at least 22% since the overall antenna size is only 35 × 10 × 0.8 mm3. The measured peak gains and antenna efficiencies are approximately 2.2/3.1 dBi and 76%/82% for the LTE/WWAN bands, respectively.
