The proposed MIMO antenna consists of two triple-band PIFAs with a symmetric slotted structure. The first resonance frequency is controlled by the total length of the main radiating strip with coupling slits (slit 1 and slit 2), which has a length of 70 mm (about 0.18 wavelengths at 0.77 GHz). The second one can be obtained by inserting on additional slit (slit 3) for WCDMA band. Moreover, the third resonance frequency can be tuned by the width of coupling slits (slit 1 and slit 2) and the position of the port 1 and 2 (P1 and P2) to cover M-WiMAX Band (2.5–2.69 GHz). To obtain a high isolation characteristic between two antennas, a symmetric slotted structure and the jointed shorting line are used to reduce the interaction between the two PIFAs. The proposed MIMO antenna has an isolation of approximately 15 dB and the envelope correlation coefficient (ECC) of the two antennas is less than 0.2 over the whole wanted frequency bands.","PeriodicalId":367154,"journal":{"name":"2011 IEEE MTT-S International Microwave Workshop Series on Intelligent Radio for Future Personal Terminals","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114343886","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}

In the HF (13.56 MHz) band, a spiral-shaped loop antenna is used and placed at the outmost region of the available space. In the UHF (915 MHz) band, a quadrifilar spiral antenna (QSA) is used because it is electrically small and features a low frequency shift by platform size and is placed in the center of the HF antenna. Measurements revealed that the antenna provides a quality factor of 56.5 in the 13.56 MHz and a gain of 2.5 dBic in the 920 MHz band.","PeriodicalId":367154,"journal":{"name":"2011 IEEE MTT-S International Microwave Workshop Series on Intelligent Radio for Future Personal Terminals","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130456949","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}

Currently, the Federal Communications Commission (FCC) allowed TV white space (TVWS) which should protect the licensed user communication to utilize for data communication. The first actual deployment of communication system operating on TVWS is implemented in our group. However, it operates in SISO and single-channel procedure. So, we will develop a second version test-bed operating various modes such as SIMO, 2×2 MIMO and multi-channel communications. From these diverse operation methods, we expect that data rate is enhanced. In this paper, we will introduce a CR RF transceiver which is equipped in our second version of test-bed based on ECMA-392 international standard.","PeriodicalId":367154,"journal":{"name":"2011 IEEE MTT-S International Microwave Workshop Series on Intelligent Radio for Future Personal Terminals","volume":"171 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133605501","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}
