Analytic Design Of Dual-Band, Dual-Polarized Lp-to-Cp Polarization Converters

2020 14th European Conference on Antennas and Propagation (EuCAP), 2020
A systematic procedure for the design of dual-band, dual-polarized linear-to-circular polarization converters is presented. This class of polarizers can convert linear polarization to orthogonal circular polarizations in two separate frequency bands. The polarization converter is composed of three electric admittance sheets.

Dual-band dual-polarization antenna array

2014 International Symposium on Antennas and Propagation Conference Proceedings, 2014
This paper is proposed a dual-band dual-polarization antenna array. This antenna is combined by one 2 × 2 dual-polarization patch antenna array and two 1 × 4 dipole antenna arrays operated in ISM 2.4-Ghz/5.2-GHz band. For the purpose to achieve dual band operation, the microstrip line diplexer is applied to combine two antenna operated in 2.4-GHz and 5.

Dual Band Dual Circularly Polarized Antenna with a Meanderline Polarizer

2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018
In this work a dual band circular polarized array antenna is presented. The proposed terminal consist of an array antenna in which the radiating elements operating around 20GHz and 30GHz are nested one into the other in order to form a dual band antenna. A meander-line polarizer is used to realize circular polarization.

FPIR: The dual polarization antenna

2013 IEEE International Geoscience and Remote Sensing Symposium - IGARSS, 2013
Full Polarization Interferometric Radiometer (FPIR) is concept of one dimensional synthetic radiometer. This paper introduces the design of the FPIR antenna. A novel linear array antenna is described with emphasis on the simulation of the antenna pattern, design of the stripline feeding network and simulation of the polarimetric isolation.

Chill Radar Dual Polarization

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
The CHILL radar was originally designed as dual polarization radar. It was put into operation in late 1971. The original concept was a dual frequency X-band and S-band system. In 1972, the idea of using it as polarization radar was suggested by Drs. Tom Seliga and Viswanathan Bringi.

Triangular Ring Antennas for Dual-Frequency Dual-Polarization or Circular-Polarization Operations

IEEE Antennas and Wireless Propagation Letters, 2014
In this letter, triangular ring (TRG) antennas are proposed for dual-frequency dual-polarization (DFDP) and circular-polarization (CP) operations. By simultaneously exciting the two orthogonal modes of the TRG, the DFDP or CP performance is achieved. By varying the vertex angle of the TRG, the frequency ratio (FR) of the two orthogonal modes could be ...
