A meandered loop antenna-in-package with parasitic structure at 2.4 GHz

摘要

Design of on-chip antennas help to create compact on-chip wireless systems. At frequencies below 5 GHz, on-chip antennas are electrically small and have low gain and efficiency. Antennas designed in packages provide a solution to the degradation in gain and efficiency at such low frequencies. In this paper a meandered loop antenna is designed at 2.4 GHz in a Low Temperature Co-Fired ceramic (LTCC) package and a parasitic structure is used to enhance its bandwidth. The antenna analysis is carried out using Advanced Design System (ADS) software. The antenna has a gain of 5.82 dBi and efficiency of 61.46%. The performance of the antenna designed in package is also compared to an on-chip antenna of size 1.2 mm × 1.1 mm designed in UMC 180 nm technology. The on-chip antenna has very low gain and efficiency of -24.5 dBi and 0.17% respectively compared to the antenna designed in package.
