Abstract: This study implements the design of an axial mode helical antenna for Ku-band satellite communication application. The paper presents design and optimization of helical antenna to resonate at 26.60GHz with 45.8dB return loss and the antenna is operating at frequency range of 18 GHz. The antenna has a peak gain of 11.39dB. The gain of the helical antennas is increasing by decreasing the spacing between the turns of coil and also the increasing the number of turns in the helical antenna. HFSS simulation tool is used in the designing. It will be measured and simulated return loss, axial-ratio, radiation pattern, and realized gain are presented and discussed.
