An on-package planar inverted-F antenna for WLAN application

Abstract

A novel on-package planar inverted-F antenna (PIFA) is proposed in this paper. The on-package PIFA consists of a single folded copper plate and has several advantages including compact size, light weight, low cost and easy fabrication. Besides, the antenna radiation pattern is omnidirectional in H-plane. The coupling effect between the on-package PIFA and the RF components in the shielding package is investigated. It is observed that the antenna performance is rarely changed even though the RF component is embedded in the package. In addition, the best isolation between the antenna and RF components can be achieved when the components are appropriately arranged in the package.
