چکیده
Antennas have come to play a significant role in the reception and transmission of electromagnetic radiation or signals which turn improved scientific research various areas where they been used. Astronomy is not left out; as study everything beyond earth’s atmosphere, useful travel great distances reach us. Hence need for equipment detect such signals. The Helical Antenna known possess high gain (directivity) can process with any type orientation/polarization implies sensitivity hence desire use it. Simulation was done using legacy 4NEC2 software. purpose this paper design circularly polarized helical antenna operating axial mode that suitable detection neutral hydrogen line emission at frequency 1420 MHz show how it be used feed an off-set parabolic dish.

متن کاملHelical Antenna Design for Image Transfer
Nowadays, there are high demands on the transmission of visual information between devices. It is expected that the image will be transmitted at high speed and if it is possible at all times. The helical antenna designed in this paper works at the frequency of 5.820GHz for which are suggested standards for signal transmission. It is assumed to insert the product into Unmanned Aerial Vehicles as...
متن کاملDetection of Ultraweak Photon Emission (UPE) from Cells as a Tool for Pathological Studies
Objective: It is well-known that all living cells emit ultra-weak photon emission (UPE), which is due to byproducts of chemical reactions in cell metabolisms. It has been shown that Reactive Oxygen Species (ROS) in the cells enhances the UPE intensity. The magnitude of such UPE is extremely weak (i.e. a few to 103 photons/ (sec.cm2)), and the detection of such ultra-weak signals is hardly possi...
