Abstract
An analysis is made of the performance of a radiation-coupled dual-L antenna (RCDLA). In the simulation the antenna is mounted on the back side of the hand-held terminal, making use of the metallic housing as a shielding structure. The simulations show that this structure has a similar performance to that of the recently proposed full short circuit planar inverted-F antenna (FS-PIFA) in terms of shielding and radiation characteristics. In terms of bandwidth, size, and matching capabilities the RCDLA outperforms the FS-PIFA. Placement of the antenna on the back side of the housing instead of the top of the terminal results in a radiation pattern that points away from the user's head regardless of the antenna type.Keywords
