Unlike other conventional solutions, including absorbent cavity backing and resistive loading, this method incorporates the concept of low-pass filtering with the two-wire transmission line behavior of the spiral antenna.

With a resonant bandwidth of about 30 MHz (using a 10 dB or better return-loss standard), there is significant room for improvement that direct antenna modulation can offer to the information bandwidth of the system. By driving the antenna at resonance and directly modulating it with an integrated Schottky diode being biased by an external pulse train, the frequency of this external modulating signal is predicted to far exceed the resonant bandwidth of the antenna and still produce a clear demodulated waveform at the receiving end of a basic communication system","PeriodicalId":6423,"journal":{"name":"2006 IEEE Antennas and Propagation Society International Symposium","volume":"56 1","pages":"909-912"},"PeriodicalIF":0.0,"publicationDate":"2006-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75899126","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}

The structure was built up with elements identical to those used in the 10,000-element array. Models of the validation array were constructed using both CFDTD and XFDTD. The array radiation patterns were shown for 0deg, 30deg, 45deg, and 60deg scan angles at the center frequency of 1.75 GHz. The beam was scanned in the Phi = 90deg plane. The solid lines represent CFDTD data while the dotted lines indicate the corresponding XFDTD set. As the beam is steered away from boresight, the 3-dB beamwidth increases from 12.9deg at boresight to 26.2deg at the 60deg scan angle. The first sidelobe level is about 13 dB below the peak when the main beam is pointed at boresight. The total change in peak sidelobe level is 4.0 dB as the beam is scanned from boresight to 60deg. The array directivity calculated with CFDTD is 23.0 dB, which is within 0.2 dB of the value given by XFDTD. Furthermore, the scan loss from 0deg to 60deg is observed to be 3.0 dB with CFDTD and 2.8 dB with XFDTD. These values are consistent with expectations for a well behaved array with 0.5lambda element spacing","PeriodicalId":6423,"journal":{"name":"2006 IEEE Antennas and Propagation Society International Symposium","volume":"60 1","pages":"1571-1574"},"PeriodicalIF":0.0,"publicationDate":"2006-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72735056","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 simple yet effective dry powder compacting method - \"sand painting\" was invented that is capable of producing multi-layer multi-ceramic variations in 3D.
