It is known to us, double-ridged horn antenna is one of common and important antenna types, it has been widely used in the EMC, measurement, radar and communication system. A 118GHz double-ridged horn antenna that possesses high performance is designed with the HFSS. VSWR, Gain and radiation pattern of the antenna can fulfill engineering demands based on the simulation of HFSS. Further, this paper...
This paper shows the design process and measurement data for a modified bi-directional equiangular spiral antenna fed by a microstrip to parallel-strip to twin-line transition on two substrates (20-mil thickness) with three layers (aligned vertically). By etching holes out of the spiral arms at the locations where the tapered parallel-strip line passed underneath, the impedance mismatch caused by...
In this paper, we are going to discuss about the current trends in the design of Microstrip M patch antenna intended for various applications and it is a innovative nature never tried out earlier. This opens up a new avenue for different frequency ranges and new applications yet easily realizable with maximum advantages. In rectangular micro strip patch antennas [RMSA] with negative capacitance and...
