The antenna can be implemented with a small dimension similarly to the conventional strip-type slot. Based on the simulation and measurement results, triple-band antenna using two U-type slots are very effective in rejecting unwanted frequency in terms of its selectivity and small real estate. The overall dimension of the antenna comes around 30 mm×30 mm×1mm. The measurement results show that the antenna offers excellent performance with Bluetooth ranging from 2.28 GHz to 2.9 GHz, WiMAX ranging from 3.3 GHz to 3.85 GHz and wireless local area network (WLAN) ranging from 4.72 GHz to 6.4 GHz. The proposed antenna gives bidirectional pattern in the E-plane and omni-directional radiation pattern in the H-plane over the frequency range and relatively stable. This antenna configuration would be quiet useful for wireless communication systems.","PeriodicalId":211786,"journal":{"name":"2010 International Symposium on Signals, Systems and Electronics","volume":"293 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133978304","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}

A fully differential feedback configuration is adopted, and the variable gains are achieved by switch controlled resistor (SCR) network. DC feedback technique is also utilized to eliminate the DC offset. SCR network layout design is essential to maintain the accuracy of the gain value under process variations. Local and global common centroid symmetric layout techniques are applied to ensure the matching of the resistors in SCR network. Post-simulation results show that the PGA has 0dB∼60dB variable gain range and 1dB gain resolution; the minimum DC attenuation is 20dB over whole gain range; the pass-band range is 10.8Hz∼20.15MHz under most gain configurations; output swing is 1.4V; and the PGA consumes 3.7mA current with 1.8V supply voltage.

It will be used on the offshore oil platform and provide atmospheric soundings of physical temperature and liquid water vapor using channels in the oxygen resonance band (6.8GHz) and water vapor resonance band (23.8GHz). The other channels at 10.7GHz, 18.7GHz and 37GHz are used as atmospheric windows, each with dual polarization. The measurements at various combinations of these frequencies and polarization will obtain many geophysical parameters such as the sea-surface temperature, near-surface wind speed, sea ice types and so on. The multi-frequency microwave radiometer is a five frequencies, ten channels and linear polarization system. The receiver is working at total-power mode with super heterodyne style. And the data processing and system control unit is used of operating mode control, data acquisition and digitizing, automatic gain control, state control of the radiometer system and communication with the remote computer system by asynchronous serial interface. Besides, an absolute calibration and a quasi-real-time calibration method used in the multi-frequency MWR are presented and the relative result is also discussed, which guaranteed the high resolution of the multi-frequency microwave radiometer system.","PeriodicalId":211786,"journal":{"name":"2010 International Symposium on Signals, Systems and Electronics","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124143111","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}
