In comparison with metasuface-based beam-scanning method, metasurface- based compressive sensing for DOA estimation has superior performance with smaller sampling length. A proof-of-concept experiment is made to verify the feasibility of programmable metasurface for DOA estimation. The programmable metasurface can achieve estimation with only a single channel and small sampling length, which is cost-effective and can be widely used in the internet of thing (IoT) application.","PeriodicalId":146561,"journal":{"name":"2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127367985","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}

It is fed by a microstripcoupled slot from bottom, with an open stub of the microstrip feedline elaborately designed to provide a radiation null, and two pairs of the \"┥\" shaped slotlines are introduced on the coupling slot to generate two radiation nulls at band edges and obtain filtering characteristic. In this design, two resonant modes are excited to provide two operating bands at 3.5 and 5.06 GHz, respectively. Lower operating band is caused by dielectric resonator (DR), while higher operating band is achieved by the slotlines. Consequently, a dual-band FDRA without involving extra filtering circuits is obtained and simulated.

The proposed PA is composed of a packaged GaN device, an input / output radio frequency (RF) signal matching network, as well as a DC bias network. The optimal output load is optimized after a trade-off between achieving a high output power and a high power added efficiency (PAE). As the transistor is not unconditionally stable, stabilization has been taken into account in the DC bias network design in such a way that the RF performance is minimally affected. Finally, the layout is finely tuned in order to optimize the interconnection parasitics and to minimize the performance degradation. Characterized with a standard measurement setup with two SMA connectors, the measured result shows that the proposed PA achieves a power gain of 11 dB with an output power of around 35 dBm.","PeriodicalId":146561,"journal":{"name":"2020 9th Asia-Pacific Conference on Antennas and Propagation (APCAP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125508073","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}
