Dual-Band Dual-Linearly Polarized Transmitarray at Ka-Band
2020 50th European Microwave Conference (EuMC), 2021 We present here the design and optimization of a dual-band dual linearly-polarized transmitarray antenna with a 1bit phase resolution (i.e. two phase states with 180° of relative phase-shift). The antenna operates in both downlink and uplink K/Ka-bands (17 – 21 GHz for the lower frequency band, and 27 – 31 GHz for the upper one) and could be used for ...

ISPRS International Journal of Geo-Information, 2021 Since many Wi-Fi routers can currently transmit two-band signals, we aimed to study dual-band Wi-Fi to achieve better positioning results. Thus, this paper proposes a fingerprint positioning method for dual-band Wi-Fi based on Gaussian process regression

Dual-polarized dual-band antenna element for ISM bands [PDF]
2009 IEEE Antennas and Propagation Society International Symposium, 2009 A dual-band element that operates in two separate industrial, scientific, and medical (ISM) bands is presented that provides dual-linear or dual-circular polarization in each band. The element is ideal for wireless communication applications utilizing multiple protocol and/or Bluetooth technology.

Dual-band single-pixel telescope [PDF]
Optics Express, 2020 Single-pixel imaging systems can obtain images from a wide range of wavelengths at low-cost compared to those using conventional multi-pixel, focal-plane array sensors, especially at wavelengths outside the visible spectrum. The ability to sense short-wave infrared radiation with single-pixel techniques extends imaging capability to adverse weather ...
