Abstract
Circularly Polarized Printed Helix Antenna for L- and S-Bands Applications
Highlights
Polarized (CP) antennas have excellent behavior in adverse weather conditions and motive transceivers, they are used widely in wireless communication systems [1,2,3,4]
In [6], a planar helical antenna is described, which is utilizing printed strips with straight-edge connections implemented by plated via-holes
Conical and inverted conical printed quadrifilar helical antennas in [9], a helical antenna with non-uniform pitch profile in [10], and quadrafilar helix antenna used on Alsat-1 S-band transmitter in [11] are the other works reported about helix antennas
Summary
Polarized (CP) antennas have excellent behavior in adverse weather conditions and motive transceivers, they are used widely in wireless communication systems [1,2,3,4]. Conventional wire helical antennas, known as a type of traveling wave antennas, have excellent CP characteristics [5]. These helical antennas are not appropriate for compact terminals, and their fabrication and impedance matching process are tedious. To solve this problem, several designs with different techniques have been reported in the past years. In [7], an origami reconfigurable axial-mode bifilar helical antenna is offered. In this design, an analytical method is developed for designing an origami helical antenna that mimics a standard helical antenna. Conical and inverted conical printed quadrifilar helical antennas in [9], a helical antenna with non-uniform pitch profile in [10], and quadrafilar helix antenna used on Alsat-1 S-band transmitter in [11] are the other works reported about helix antennas
