Number of papers have been reported for dual-band operation such as probe feed U-slot loaded patch antenna , notch loaded patch antenna , shorting pin using E-shaped patch antenna , L-shaped patch antenna , H-shape stacked patch antenna , shorting pin loaded compact antenna , C-shaped microstrip antenna and F-shaped patch antenna . Effect of Capacitive loading on slot loaded Dual Band ... modifying the formulas for reactively loaded patch with slot loading. Broadband antennas provide higher bandwidth at the expense of their high thickness. Dual band microstrip antenna with capacitive loading can be an alternative to large bandwidth antennas, especially when a large bandwidth is required for Dual-band slot-loaded patch antenna - IET Journals & Magazine Dual-band slot-loaded patch antenna Abstract: A new patch antenna is analysed which provides dual-frequency operation by means of two narrow slots close to the patch radiating edges. The two modes of operations show similar radiating properties. The ratio between the two frequencies can be well controlled within a range varying from 1.6 to 2 ... Slot Loaded Compact Microstrip Patch Antenna for Dual Band ... Slot Loaded Compact Microstrip Patch Antenna for Dual Band Operation Avisankar Roy1, *, Sunandan Bhunia2, Debasree C. Sarkar3, and Partha P. Sarkar3 Abstract—A novel design of a compact microstrip patch antenna using meandering technique is proposed in this paper where the designed antenna seems to behave as a microstrip patch loaded

designed a slit-loaded notch-cut patch antenna based on investigations. The antenna patch is fed by coaxial feed. Meandering techniques and the new design are simulated in HFSS environment. Results show good return loss for new design. Index Terms: Patch antenna, Broadband, Compact, Meandering, Resonant Frequency. DESIGN CONSIDERATIONS OF DUAL-FREQUENCY AND … the use of two sectorial slots on a circular patch [5], a pair of bent slots on a triangular patch [6], a pair of toothbrush-shaped slots on a rectangular patch [7], a pair of dual-bent slots on a rectangular patch [8] and so on. We propose in this article another promising slot-loaded circular microstrip antenna with
far apart, dual-frequency patch antennas may avoid the use of two different antennas; a typical case is that of SAR. As is well-known, the present SAR antennas employ dirferent arrays for each band. The trend of SAR antennas of the future generation is to cover at least two of the three bands with a dual-frequency antenna. This
The dual band frequency of this prototype antenna was controlled by adjusting rhombus stub and bent-slit loaded. In simulation of the return loss, gain and radiation pattern was using software IE3D program. 2. Structure of Antenna The structure of microstrip antenna with rhombus stub and using a pair of bent-slits loaded Stacked Textile Antenna for Multi Band Application Using ...

More ANTENNA information. Dualband bent slot loaded patch antenna. Image of the Dualband bent slot loaded patch antenna. This compact planar antenna supports TM01 and TM10 modes on the patch structure due to the introduction of slots, resulting in dual-band operation. The ratio between the upper and lower frequencies is mainly controlled by the Design of Multi-band U-Slot Microstrip Patch Antenna for Ansari et al [7] reported on a U-slot loaded patch with a coaxial feed point, using equivalent circuit concept and obtained two resonant frequencies. A close agreement was found between analysis and simulation results. Ghalibafan and Attari [8] reported on a new dual band microstrip antenna with U-shaped slot where a broadband A SLIT-LOADED NOTCH-CUT PATCH ANTENNA FOR … designed a slit-loaded notch-cut patch antenna based on investigations. The antenna patch is fed by coaxial feed. Meandering techniques and the new design are simulated in HFSS environment. Results show good return loss for new design.
