Abstract—
There is a tremendous demand for antennas with very broad bandwidth and gain so that one antenna can cover the entire frequency range of the satellite communication applications, which are rapidly expanding with the current technology for diverse platforms. Helical antennas are ideal for these applications due to their distinctive qualities such as circular polarization, wide bandwidth, excellent gain, and low-profile conformability. For transmitting and receiving applications, which comprise frequency ranges of 240MHz to 270MHz and 290MHz to 320MHz, respectively. A new design of circularly polarized double-wire helical antenna employing the butterfly approach has been created in this study. An antenna was designed, simulated, analyzed, and fabricated before being experimentally measured for important parameters such as axial ratio, gain, 3dB beamwidth, and voltage standing wave ratio.
Keywords
—Single–wire helical antenna, double-wire helical antenna, butterfly technique, transformer feeding, ultra-high-frequency satellite communication
