The antenna dimensions are 12 × 12 × 1.6 mm3 and is placed within laptop hinges, which is favorable for convertible laptops since they usually come with narrow bezels. The monopole is installed inside the hinge cap. Its resonant modes are not only provided by the monopole structure but are also affected by surrounding ground edges. Simulation and measurement results demonstrate that the proposed design can cover both IEEE 802.11b (2.4–2.48 GHz) and 802.11ac (5.15–5.35, 5.725–5.825 GHz) bands.

The radiating device of cavity-backed slot filtering antenna is a U-shape slot located on the top metallic plane of cavity. The satisfying filtering performance of antenna is obtained by Tshape feedline and SIW cavity resonator. As compared to the other SIW filtering antennas, this antenna obtains a favourable filtering performance, simply. Commercial software HFSS is used to verify the proposed antenna.

The basic idea is that \"the energy of the electromagnetic wave can pass smoothly when it is less than the safety threshold, and it is automatically shielded when it is greater than the safety threshold\". The adaptive switching characteristic can effectively protect the strong electromagnetic pulse without affecting the normal operation of the equipment. At present, the design of ESS rarely has a narrow band and the shielding performance is greater than 30dB. In this paper, a narrow-band ESS operating in L-band is designed. The results of CST show that the working frequency band of the structure is between 1.426GHz and 1.623GHz, which covers the working frequency range of the airborne GPS antenna 1.5~1.57GHz. The insertion loss is less than 3dB when it is in the wave-transparent state, and the shielding efficiency is more than 30dB when it is in the shielding state. It can be used for high-power microwave protection of the airborne GPS antenna.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131341609","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}

When developing communication algorithm on Field-Programmable Gate Array (FPGA) based Software Defined Radio (SDR) system, traditional steps include the algorithm simulation, FPGA synthesis and implementations, hardware validation and iterative adjustment. In general, the algorithm simulation step is entirely isolated with hardware environment. More pressures are added on hardware debug process and this will lead to a longer production period. New generation of FPGA products consists of both ARM hard cores and FPGA arrays. Due to its existence of ARM core, data acquiring system is easy to be built. When developing algorithm and optimizing parameters, data could be obtained directly from hardware and be simulated on computer in real time. The algorithm could be directly verified on hardware environment without building FPGA model. Therefore, algorithm developing process could be accelerated.","PeriodicalId":254491,"journal":{"name":"2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131037962","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}
