Antenna-Filter Integration for Wireless Applications

Abstract

This paper presents a triple band antenna integration with a band-pass filter by optimizing the impedance at the interface between the two. A miniaturized antenna is designed at three different frequencies and integrated with a filter and at the output a single frequency of 2.4 GHz is achieved. The filtenna is made-up on FR-4 epoxy substrate and 4.4 is the dielectric constant, and having 1.6mm thickness. The proposed structure is having low cost, miniaturized in size and gives good filtering performance.
