Size reduction and parameter improvement of PA

This examination was completed decrease the measure of the patch antenna (PA) Not only size reduction was achieved as well as improvement of the directivity and proficiency of patch antenna by making some defect on the ground in this examination paper was achieved. More than expected results have been achieved, it is noticed that within the sight of the imperfection in the ground, the antenna is more order and has a higher pick up. This proposed patch is designed at the frequency of 5.5GHz. The proposed structure is a replica of key with two parallel blocks on both sides. Defect on the ground plane generally distributes the radiating frequency and make antenna more efficient than ever before.
