Abstract :
In this paper, the simulation of three monopole with G type structure is proposed consisting of one closed rectangular wire loop and one open rectangular wire loop with maximum horizontal and vertical dimensions approximately of L1 = L2 = L3 =.25lambda, h=202lambda, w = .1834lambda, l =.3487lambda and having wire radius of 2 mm. Each of the structure is analyzed on perfect ground and on CUBESAT and their various performance parameters such as gain, bandwidth and input impedance is determined. The three structures were designed at centre frequencies of 150 MHz, 180 MHz and 330 MHz. These have the bandwidth of 6%, 32.77% and 41.8%, gain of 3.757 dB, 2.691 dB and 2.774 db, having input impedance of 234.2+31.886i,55.905-10.93i and 54.633+7.39i at the resonant frequencies respectively when mounted on a CUBESAT. The software used to analyze and simulate the proposed antenna is numerical electromagnetic code (NEC) -Win PRO. The numerical results of the designed wideband antenna are presented and analyzed.
