And the antenna coupled gap of monopole antenna and the length of λ/2 transmission line will make the isolation be changed. The dual-band antenna is fabricated by FR4 substrate.

The length of ground plane, 110 mm, can obtain a near 0.75λ pattern. In this paper, using a closed-end antenna jams with other antennas difficultly, but it will get lower total radiation efficiency.

Most aspects for this standard depict the link between roadside equipments to vehicles under outdoor scenarios. However, when vehicles move to undercover car parking or indoor constructions, the transmission link is automatically detached from roadside equipments. Therefore, it is a better approach if vehicles can extend their services under indoor scenarios via IEEE 802.11p. In this light, this paper presents an investigation on using this standard for indoor approach. The real prototype using GNU Radio and USRP (Universal Software Radio Peripheral) has been implemented for data measurements. The results reveal the possibility of using this standard for indoor communication.","PeriodicalId":178493,"journal":{"name":"2012 IEEE Asia-Pacific Conference on Antennas and Propagation","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133864701","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}

Isolation enhancement using the corrugated structure with a height of 0.65 mm is up to 10.3 dB in simulation and is assured over the frequency of 57 to 66 GHz.
