Abstract

ABSTRACT


This paper proposes a second order dual-band bandpass filter using two half wavelength stepped impedance resonators to operate at Wi-Fi frequencies of 2.45 GHz and 5.45 GHz having bandwidths of 560 MHz and 470 MHz respectively. Increased coupling is achieved with the use of ground slots below the coupled line section.


Keywords: dual-band, stepped impedance resonator, bandpass filter, ground slots, Wi-Fi, WLAN
