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 کاملRadiation Properties Enhancement of Triangular Patch Microstrip Antenna Array Using Hexagonal Defected Ground Structure
This paper presents a hexagonal shape defected ground structure (DGS) implemented on two element triangular patch microstrip antenna array. The radiation performance of the antenna is characterized by varying the geometry and dimension of the DGS and also by locating the DGS at specific position which were simulated. Simulation and measurement results have verified that the antenna with DGS had...
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 کاملReconfigurable Microstrip Patch Antenna with Switchable Polarization
A new reconfigurable microstrip patch antenna allowing switching between two circular polarizations is proposed. It consists of a square radiating patch and a 3 dB hybrid coupler. Using only a single-polar-double-throw (SPDT) switch, the polarization switching can be achieved. This design of the dc-bias network is extremely simple. From experimental results, the proposed antenna avoids the freq...
متن کاملReconfigurable Microstrip Patch Antenna with Switchable Polarization
Kyungho Chung et al. 379 ABSTRACT⎯A novel reconfigurable microstrip patch antenna with frequency and polarization diversities is proposed. A U-slot is incorporated into a square patch, and a PIN diode is utilized to switch the slot on and off, which realizes the frequency diversity characteristic. The polarization diversities among linear polarization (LP), right-hand circular polarization (RHC...
