The phase shifting element supporting circular polarization is first designed and investigated. Under the control of the driving voltage, the reflection phase of the array element can be switched between 0 and 180 degrees with the change of the LC molecules’ state. Consequently, a circularly polarized beam scanning reflectarray is realized by the phase shifting elements periodically arranged on a plane and illuminated by a feeding horn antenna. Numerical simulations are conducted to demonstrate the reflectarray antenna’s performance. Results show that, with the one-bit phase shifting resolution, the antenna achieves the beam scanning range from -30 degrees to -10 degrees while the gain reaches up to more than 20 dB and the axial ratio keeps less than 3 dB.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123671008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The element with variable size of capacitive patches are judiciously distributed across the lens to provide a gradient phase function so as to compress the wave-front width. A lens antenna, composed of a patch antenna and the proposed lens above it, are designed, simulated and characterized.

The coaxial probe feed position is then appropriately selected to excite the desired CMs with respect to their modal currents.

In the off-line phase, the hierarchical clustering approach is proposed to distinguish the attacked training data and the attacked-free training data, firstly. By the above data pre-processing, the attacked RSS measurements is found and can be deleted. Then, the online sequential extreme learning machine (OS-ELM) algorithm is used to training the attacked-free data in turn. In on-line phase, according to the obtained RSS measurements, the obtained regression models are straightly used for final position estimation.
