Abstract

This manuscript describes the design and implementation of miniaturized slot antenna with two-stage impedance matching circuit for 800MHz and 2GHz up and down link multiband application. The impedance matching circuit is based on the 2-stage band-pass filter (BPF). We fabricated this multi-band slot antenna on FR4 substrate and measured the radiation patterns and frequency characteristics. Also, the proposed multiband antenna was implemented on the main circuit board and tested the frequency properties.
