I'm finishing the carrier of Electronical Engineering at Mendoza, Argentina. A MSA has many attractive features like low profile, light weight, small volume and low production cost. shapes of microstrip antenna. 3 dB beamwidth is approximately equal to the angle from the peak of the power to the first null (see figure at right). The frequency chosen for the microstrip antenna is 2.4GHz7 and it has been chosen from IEEE 802.11 which is for the Wireless Fidelity (WiFi) network. 1 Fig. �`���Yɣ28n�Oc%��I�N��Y ����qvl�u ��$��([A&=i�T�`\6�!?
