Symmetrical and asymmetrical Microstrip Array Antenna

The power efficiency of the antenna is aimed to reducing power loss (losses). Low Losses making optimal antenna performance in transmitting and receiving waves. Range of the antenna can also be optimized because of greater power can be transmitted, thus reducing the need transceiver devices that consume a lot of power. The author uses a microstrip antenna array with a number of patches to different made to find a different gain value. The results of the simulation of antenna gain antenna values obtained successively dBi 2.55, 3.08 dBi, 4.32 dBi, 5.05 dBi and 6.21 dBi. As for the antenna efficiency is obtained 0.98272323, 0.98395813, 0.9851897, 0.98815117 and 0.99053464. The results of the measurements obtain fabricated antenna consecutive obtained gain value -2.44 dBi, -2.05 dBi, -0.77 dBi, -0.63 dBi and 2.00 dBi. From measurements of the radiated power antenna efficiency values obtained third consecutive 0.3937, 0.4908, 0.5529, 0.57, and 0.6262. The results of this research concluded that the greater the value of the gain of the antenna, the higher the efficiency of the power.
