“…M. Euler and et al achieved minimum Axial Ratio 3dB and axial ratio bandwidth of 0.5% with -3.2 transmission loss of polarizer [14]. Masa-Campos and et al used the double-layer polarizer approach to obtain circular polarization in order to 3dB axial ratio on operational bandwidth of 5.7% [15]. G. I. Kiani and et al observed the transmission loss 6 dB with narrow band and 1.0 axial ratio through polarizer at 75 GHz [16].…”

Abstract-In this paper, a novel design of broadband frequency selective surface dual layer circular polarizer based on quarter wave plate is presented to analysis transmission characteristics at operated frequencies for the X-band applications. The efficient techniques are employed to achieve high polarization efficiency, optimal performance and good circular polarization around resonant frequencies. Widening bandwidth through polarizer has been an important issue for researchers; therefore significant technique is employed to improve bandwidth widening of polarizer at transmitted frequencies. Our results show that cross dual layer polarizer transmits left handed circular polarization (LHCP) at 9.60 GHz and right hand circular polarization (RHCP) at 10.65 GHZ with axial ratio across 9.24-10.99=17.12% bandwidth, respectively.

“…In order to build an instrument with hundreds of array elements, each unit needs to be small to allow for close-packing. Other kind of circular polarizers such as microstrip polarizer [17][18][19][20][21][22][23] also have the disadvantage of narrow bandwidth and low efficiency due to losses of conductor, dielectric and surface wave.…”

Abstract-A novel type of dual circular polarizer for simultaneously receiving and transmitting right-hand and left-hand circularly polarized waves is developed and tested. It consists of a H-plane T junction of rectangular waveguide, one circular waveguide as an Eplane arm located on top of the junction, and two metallic pins used for matching. The theoretical analysis and design of the three-physicalport and four-mode polarizer were researched by solving ScatteringMatrix of the network and using a full-wave electromagnetic simulation tool. The optimized polarizer has the advantages of a very compact size with a volume smaller than 0.6λ 3 , low complexity and manufacturing cost. A couple of the polarizer has been manufactured and tested, and the experimental results are basically consistent with the theories.

“…However, the design of a broadband circularly polarized patch antenna that uses a single feed has long been a challenging problem, as compared to the design of linearly polarized (LP) and the dual-fed circularly polarized (CP) patch antennas [7,8]. Especially, the single-fed single-patch CP antenna has inherently narrow impedance and axial ratio (AR) bandwidths of 1%-2% [9,10].…”

Abstract-The paper demonstrates a novel antenna which can achieve a broad impedance bandwidth and circularly polarized bandwidth with a suspended corner-truncated square patch and a new probe-fed rectangular strip. By incorporating a probe-fed rectangular strip inside a high substantial cavity (∼ 0.144λ 0 ), a broad impedance bandwidth (VSWR < 2.0) of 770 MHz (31.43%) is achieved. To obtain a good circularly polarized (CP) bandwidth matching with the impedance bandwidth, two stubs with optimized lengths are loaded at the non-radiating edges of the corner-truncated square patch symmetrically. Measured results show that the CP antenna features a wide operating bandwidth of 10% ranging from 2.41 GHz to 2.66 GHz (VSWR < 1.5 and axial ratio < 3 dB) and that of 22.45% ranging from 2.31 GHz to 2.86 GHz (VSWR < 2 and axial ratio < 6 dB) and good radiation patterns with cross-polarization level (LHCP) lower than the co-polarization level (RHCP) by more than 20 dB at the broadside direction. The average gain of this antenna is recorded as about 8.16 dBi across the operating bandwidth.
