Multi-band miniaturized slot antenna with two-stage bandpass filter

This paper presents the design and implementation of miniaturized slot antenna with two-stage impedance matching circuit for 800MHz and 2GHz up/down link multiband application. Our proposed multi-band antenna is designed and simulated by using commercial three-dimensional electromagnetic (EM) field simulator. Also, we fabricated this multi-band antenna on FR4 substrate and measured the frequency characteristics.
