Abstract

A compact dual‐band (WLAN 11b; 2.4 GHz ∼ 2.5 GHz, 11a; 5.15 GHz ∼ 5.825 GHz) 2‐channel Multiple Input Multiple Output (MIMO) antenna for portable media player (PMP) applications is presented. The proposed antenna is composed of a planar inverted F‐shape antenna (PIFA) operating at 2 GHz band and a loop antenna operating at 5‐GHz band. The antenna made up of the composite loop and PIFA antenna (CLPA) with connecting line face to the feed point and is orthogonally arranged at the edge of the ground plane for reducing mutual coupling. The antenna shows polarization and pattern diversities with excellent isolation characteristics. The two antennas were connected with each other in the bottom side to improve the isolation at 5‐GHz band. The proposed antenna has a sufficient gain in WLAN service band and is compact sized for the PMP applications. © 2010 Wiley Periodicals, Inc.
