A novel dual-band bandpass filter (BPF) is proposed in this paper. The BPF consists of two slow-wave resonant cells, which is composed of a microstrip T-stub and nested interdigital defected ground structure with the broadside-coupled (BC) transition. Strong slow-wave effect is employed by this structure, which leads to ultra-wide stopband response. Meanwhile, the nested interdigital defected ground...
This paper describes a novel dual-band patch antenna on organic magnetic substrate for wireless local area networks (WLAN) wireless communication (at 2.4 and 5 GHz). The dual-band operation is obtained by embedding a pair of L-shaped slots. The magnetic material is adopted because the substrate can reduce the size of antenna 40%, comparing with rectangular microstrip antennas on normal dielectric...
