A dual-band aperture-coupled CP microstrip patch antenna is presented. It contains only one radiator and one cross-slot. The vertical and the horizontal slot are of equal length which is about 1.0 to 1.5 times the side-length of a square microstrip patch antenna. It is found that the current on the patch flows sequentially in +y, +x, -y, Miniaturized Wideband Aperture Coupled Microstrip Patch ... In 2004, Rao and Johnston proposed a modified aperture coupled microstrip antenna in which they employed a back cavity to block radiations from the slot. In 2005, Rao et al. presented a new aperture coupled microstrip slot antenna to improve the

The performance of the antenna has been confirmed by both measurement and simulation. The antenna gain is enhanced and backlobe radiation is reduced by placing a12. Adrian, A. and D. H. Schaubert, "Dual aperture-coupled microstrip antenna for dual or circular polarization," Electron.

An Introduction of aperture coupled microstrip slot antenna with microstrip line feed has been discussed [14]. In this paper a simple but accurate design method from air gap aperture microstrip antenna is presented. The dual-band operation of air gap aperture coupled microstrip antenna are useful in many application such as dual-

Broadband Focusing Using Aperture-Coupled Microstrip Patch Antenna Arrays Payam Nayeri, Atef Z. Elsherbeni, and Randy L. Haupt EECS, Colorado School of Mines, Golden, CO 80401 Abstract—A new design for a broadband focused planar array using aperture-coupled stacked patches is presented. The array has a Dolph-Tschebyscheff amplitude taper. Mutual

Bandwidth Optimization of Aperture-Coupled Stacked Patch ... Permittivity and thickness are equally important for bandwidth antenna. The analysis of the antenna was done by the usage of IE3D - Zeland Software (method of moments - MoM). The method has been applied to the microstrip-fed slot antenna and to the aperture coupled antenna with a good result when compared with measured data. Coupling Effects of Aperture Coupled Microstrip Antenna and slot is chosen and tuned perfectly, it gives an optimum impedance bandwidth with an improved radiation pattern. Keywords—:-microstrip antennas,aperture,coupling I. I.INTRODUCTION Aperture coupling is an indirect method of feeding the patch. Aperture coupled microstrip antenna couples the patch antenna with microstripline through an ... Slot Microstrip Antenna for 2.4GHz RFID Reader Application respectively. By using the strip and slot, the proposed antenna deals properly with frequency shift for real application when embedded inside a handheld reader. V. CONCLUSION Thus the slot microstrip antenna was designed.The antenna shows good performance at 2.4GHz. Antenna gain, directivity, efficiency and return loss are measured.
