A dual-band internal antenna with a parasitic patch for mobile handsets and the consideration of the handset case and battery

Abstract

This letter proposes a compact internal antenna of the modified planar inverted F antenna (PIFA) type with a parasitic patch. It also considers the influences of the handset case and battery. A low-profile design is implemented on both the top and bottom sides of the FR-4 substrate. The proposed antenna, with the small size of 27.5/spl times/12/spl times/7… (More)
