In this paper, isolated elements dual-band microstrip patch antenna array (MPAA) is presented for wireless applications. The proposed antenna array consists of two patches with half wave length of the higher frequency center to center spacing. The antenna is designed on FR4 substrate with dielectric constant of 4.3 and thickness of 1.6 mm. The dual-band behavior is obtained by etching U-shape slot...
This paper introduces new compact DGS Resonators and an approach, in which lumped and tunable element are add within the DGS Resonating structure in certain places to obtain compact high performance and tunable filters. A comparison study of the combined resonators is presented to identify their relative advantages, disadvantages and their suitability for specific applications like cygnus system for...
