A new modified helix antenna is introduced which combines the helix and monopole together and forms improved current distribution. The character makes it more convenient for gain improvement and size reduction. The antenna is designed and simulated with Ansoft HFSS which is based on Finite Element Method (FEM). According to the rule, some models are fabricated for use on two-way radio. The measured...
The analysis of antenna is very important as it is one of the main contributions to the whole RCS of low-observable platforms. A new fractal slot microstrip patch antenna is designed and fabricated to show good radiation pattern and low RCS. The work is useful for the design of low RCS antenna on stealth aircraft
