Aperture Coupled Microstrip Antenna Design and Analysis Aperture Coupled Microstrip Antenna Design and Analysis Michael Paul Civerolo A linearly-polarized aperture coupled patch antenna design is characterized and optimized using HFSS antenna simulation software . This thesis focuses on the aperture coupled patch antenna due to the lack of fabrication and tuning documentation Aperture coupled Wide-Band Micro Strip Antenna Design patches bandwidths up to 70% are reported(how ever only single patch design is attempted in this project). So the parametric study, design, fabrication and testing of a wi th wide band aperture coupled antenna has been attempted in this project. And an aperture coupled antenna with 500 MHz band width was designed at 2GHz
Lohokare  highlighted Microstrip Patch Antenna Loaded with Magnetoinductive Waveguide . Chen and Zhang  described Bandwidth enhancement of a microstrip-linefed printed wide-slot antenna with a fractal shaped slot. A novel monopole antenna with a self-similar slot for wideband applications  is designd by Song and Zhang.

Wideband Microstrip Antenna Design Scott A. Wilson, Graduate Student ... discussed for aperture-coupled antenna design, a ... structure, slot and middle patch is responsible for the first minimum seen in the S11 plot of Figure 6. The Q of this valley can be adjusted by varying the substrate thicknesses, slot width or patch width. ... Slot Microstrip Antenna for 2.4GHz RFID Reader Application show that the proposed patch antenna may well ... antenna design gives a gain of dB at 2.4GHz. Formula for calculating gainvalue is, ... Thus the slot microstrip antenna was designed.The antenna shows good performance at 2.4GHz. Antenna gain, directivity, efficiency and return loss ... SLOT LOADED SHORTED GAP COUPLED BROADBAND MICROSTRIP ANTENNA Slot Loaded Shorted Gap Coupled Broadband Microstrip Antenna International Journal of Smart Sensors and Ad Hoc Networks (IJSSAN), ISSN No. 2248-9738 (Print), Vol-3, ISSUE-1, 2013 36 In the presented work, the bandwidth has been further enhanced by using the slots in parasitic patches. IE3D is the first SCALABLE EM design and
Aperture coupled Wide-Band Micro Strip Antenna Design
Ultra Wideband Microstrip Diamond Slotted Patch Antenna with ... tenna design. The antenna is designed on an FR4 sub- strate with the thickness of 1.6 mm and dielectric con- stant of 3.8. The antenna consists of a larger patch with a diamond slot, a smaller patch which serves as the feed- line and a partial ground plane. The patch antenna’s Design of a high isolation dual‐polarized slot‐coupled ... The design of a wideband dual‐polarized slot‐coupled stacked microstrip antenna with high isolation is introduced. The proposed stacked‐patch antenna is excited by both open‐ended and T‐shaped microstrip lines via two H‐shaped slots placed orthogonally so as to improve the isolation between the two polarization ports. Bandwidth enhancement of modified square fractal microstrip ... Narrow bandwidth is a major constraint of microstrip antennas. This paper illustrates the design of a gap coupled modified square fractal microstrip patch antenna which has been designed to overcome this limitation. The intended design has an impedance bandwidth of 85.42% around the resonant frequency of 1.844 GHz.
Lastly, we demonstrate application of the developed schemes to a 256-element slot-coupled patch antenna array with 101,555 unknowns.
