Design of Microstrip Patch Antenna by Introducing Defected Ground Structure
This paper proposes a novel Inset Feed Microstrip patch antenna with Z and F shape defect in ground plane. Initially simple inset feed rectangular Patch Antenna is designed and results are analyzed. Further this design is modified by etching Z and F shaped defect on ground plane. Defected Ground Structure is studied to enhance the performance parameters of microstrip patch antenna. Proposed ant...
متن کاملA Novel Design of Patch Antenna using U-Slot and Defected Ground Structure
A novel design of patch antenna is presented with double U slot structure on patch with ground irregularities. As a result tri-band response is achieved with gain reaching 0.785 to 3.75dB respectively and directivity of 5.5 to 5.6dBi. Coaxial cable is mounted with patch as medium of power. The antenna has shown minimum mismatch loss with 0 to 5% with high bandwidth response of 37 to 1200MHZ. Th...
متن کاملUltra-Compact 1.8GHz Microstrip Antenna Using Defected Ground Structure
In this letter, we have presented a microstrip patch antenna. Physical size reduction and low cost are the trends that are centralized in today’s developing technology. The simulated and fabricated results of an ultra that operates in 1.8GHz is discussed. Even t compromises are made such as low gain, narrow bandwidth etc., still this antenna provides promising features and parameters that are s...
متن کاملA Review of Defected Ground Structure (DGS) in Microwave Design
Electromagnetic bandgap (EBG) or alternatively called photonic band gap (PBG) structures have been attractive to obtain the function of unwanted frequency rejection and circuit size reduction. Researches on the PBG had been originally carried out in the optical frequency. Recently, there has been an increasing interest in microwave and millimeter wave applications of PBG circuits. This paper pr...
متن کاملDesign of Coupled Resonators Bandpass Filter with Defected Ground Structure
In this paper a four-pole elliptic function bandpass filter is designed with two ground slots. A research of microstrip bandpass filters (BPF) using defected ground structures (DGS) is presented. DGS technique allows designs of tight couplings without the necessity of using very narrow coupling gaps. The simulator Sonnet is used to design the resonator and to calculate the coupling coefficient ...
