A Novel Function Tuner with Microstrip Circuit for Slot Patch Antenna
This paper presents a design of microstrip functional tuner for slot patch antenna.It consists of a SMA-connector and an adjustable microstrip circuit.The implemented antenna was excited through a T-shape feed line being coupled to the rectangular patch.The operation frequency is designed at 2.6GHz.The connector is embedded to the rectangular patch being connected to the function tuner to control the impedance bandwidth of the proposed antenna.In this study,the impedance bandwidth of the proposed antenna can be simply controlled by adding resister on to the microstrip circuit.The impedance bandwidth of the proposed antenna without circuit loading was designed at 3.4%.If the circuit loading of 75Ω was added,the impedance bandwidth of the proposed antenna would increase to 11.4%.If the circuit loading is changed to 50Ω and 25 Ω,the impedance bandwidth of the proposed antenna would be shifted to 14.3%and 20.8%respectively.The equivalent circuit simulated by ADS for our designed functional tuner is demonstrated.The calculated and experimental results confirmed that our proposed functional tuner embedded onto the implemented antenna has good performance.
