Abstract

An innovative LDS 4G antenna solution operating in the 698-960 MHz band is presented. It is composed of two radiating elements recombined in a broadband single feed antenna system using a multiband matching circuit design. Matching interfaces are synthesized thanks to lumped components placed on the FR4 PCB supporting the LDS antenna. Measurement shows a reflection coefficient better than -6 dB over the 698-960 MHz band, with a 30% peak total efficiency. Measurement using a realistic phone casing showed the same performances. The proposed approach can be extended to additional bands, offering an innovative antenna solution able to address the multi band challenge related to 4G applications.
