Dual Null Steering and Limited Beam Peak Steering Using Triple-Mode Circular Microstrip Patch Antenna
A compact triple-mode circular microstrip patch antenna capable of creating two nulls in the upper hemisphere and steering them independently is presented. The antenna consists of a central circular patch supporting TM 11 mode, a TM 21 mode shorted annular ring around it and another shorted annular...

| 520 | |a A compact triple-mode circular microstrip patch antenna capable of creating two nulls in the upper hemisphere and steering them independently is presented. The antenna consists of a central circular patch supporting TM 11 mode, a TM 21 mode shorted annular ring around it and another shorted annular ring supporting TM 31 mode encompassing the other two radiators. Each mode is fed using two feed points to create right-handed circular polarization. Analytical and simulation studies show that by controlling the individual mode amplitude and phase ratios, radiation pattern can be reconfigured. Especially, two nulls can be generated in upper hemisphere and can be steered independently based on the ratio of applied excitation to each mode. This is a highly desirable feature for satellite receives antenna system with antijamming capability. To calculate the required modes excitation ratios, a MATLAB optimization code using a hybrid method of particle swarm optimization and pattern search was used. To apply the calculated excitation, an analog beamforming network consisting of digital variable gain attenuators, digital phase shifters, and low-noise amplifiers was used. This antenna was fabricated and tested for radiation patterns showing full hemispherical null steering along with limited beam peak steering. | ||

This antenna was fabricated and tested for radiation patterns showing full hemispherical null steering along with limited beam peak steering.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">multimode antenna</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Antenna radiation patterns</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Analog beamforming</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Patch antennas</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">microstrip patch</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Microstrip</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">null-steering antenna</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Microstrip antennas</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Antenna feeds</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">pattern reconfiguration</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sharma, Satish Kumar</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">IEEE transactions on antennas and propagation</subfield><subfield code="d">New York, NY : IEEE, 1963</subfield><subfield code="g">65(2017), 8, Seite 3838-3848</subfield><subfield code="w">(DE-627)129547239</subfield><subfield code="w">(DE-600)218496-5</subfield><subfield code="w">(DE-576)014998114</subfield><subfield code="x">0018-926X</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:65</subfield><subfield code="g">year:2017</subfield><subfield code="g">number:8</subfield><subfield code="g">pages:3838-3848</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">http://dx.doi.org/10.1109/TAP.2017.2710198</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="856" ind1="4" ind2="2"><subfield code="u">http://ieeexplore.ieee.org/document/7936590</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-TEC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_11</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_201</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">65</subfield><subfield code="j">2017</subfield><subfield code="e">8</subfield><subfield code="h">3838-3848</subfield></datafield></record></collection>

Dual Null Steering and Limited Beam Peak Steering Using Triple-Mode Circular Microstrip Patch Antenna |
| abstract |
A compact triple-mode circular microstrip patch antenna capable of creating two nulls in the upper hemisphere and steering them independently is presented. The antenna consists of a central circular patch supporting TM 11 mode, a TM 21 mode shorted annular ring around it and another shorted annular ring supporting TM 31 mode encompassing the other two radiators. Each mode is fed using two feed points to create right-handed circular polarization. Analytical and simulation studies show that by controlling the individual mode amplitude and phase ratios, radiation pattern can be reconfigured. Especially, two nulls can be generated in upper hemisphere and can be steered independently based on the ratio of applied excitation to each mode. This is a highly desirable feature for satellite receives antenna system with antijamming capability. To calculate the required modes excitation ratios, a MATLAB optimization code using a hybrid method of particle swarm optimization and pattern search was used. To apply the calculated excitation, an analog beamforming network consisting of digital variable gain attenuators, digital phase shifters, and low-noise amplifiers was used. This antenna was fabricated and tested for radiation patterns showing full hemispherical null steering along with limited beam peak steering. |
