Antenna Concept Evaluation and Improvement

The proposed antenna design seems very promising in terms of SWAP – C (“Size Weight and Power – Cost”) performances, due to the printed circuit technology selected.

Electrical performances seems promising too, nevertheless further activities of tuning and optimization of the design are necessary.

Material Selection

The material of the breadboard (ARLON AD300) was selected because is a good compromise between cost and properties suitable to demonstrate the feasibility of the antenna concept. Nevertheless the antenna substrate is the first item to improve.
