This paper describes the design of 2 GHz low noise amplifier using microwave integrated circuit (MIC) technique. The circuit was designed first to achieve maximum gain, then it designed to achieve the minimum noise, and finally some tradeoffs were done to get the minimum noise with the greatest available power gain. Also the sensitivity of the circuit with the variation of matching circuits at the...
In this paper, the concept of utilizing circular inductive posts as a simple inductive discontinuity coupling method for the implementation of in-line dual-mode rectangular waveguide filter is introduced. The use of shunt inductive posts facilitates the fabrication process and reduces filter size/weight if compared to other dual-mode inductive coupling methods. The complete design procedure of the...
This paper presents a novel design for the implementation of a patch antenna over a high impedance wire (HIW). The proposed configuration enhances the efficiency of the patch antenna to 98% together with size reduction of 75%. The performance of the patch antenna over HIW has been analyzed using both electromagnetic and circuit models. Simulated investigations have been verified by fabrication and...
