Multi-band antenna device for radio communication terminal and radio communication terminal comprising the multi-band antenna device

摘要

A multi-band radio antenna device (1) for a radio communication terminal is disclosed. The antenna device comprises a substrate and a radiating antenna element thereon having a radio signal feeding point (13), wherein the radiating element comprises a continuous trace of conductive material. The continuous trace has a first radiating portion connected to said radio signal feeding point comprising a at least partly meandered radiating portion (11) arranged distal from said radio signal feeding point (13) and connected to an elongate radiating portion (10) arranged proximal to and connected to said signal feeding point, and a second radiating portion (12) connected as a branch to said first radiating portion at a branching position (14) thereof arranged distal from said radio signal feeding point (13). The antenna device offers a minimized number of necessary contacts and improved antenna efficiency.
