Microstrip Patch Antennas - EM Lab Microstrip Patch Antennas Slide 18 The rectangular patch is the most widely used configuration for microstrip patch antennas. Transmission-Line Model It is the easiest approach to model and analyze the microstrip patch antenna. It is also less accurate, but gives a good physical insight. EM Cavity Model EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA antenna. In this paper we have seen the effect of slot on microstrip patch antenna. By the use of slot we can enhance bandwidth, gain e.t.c.. Return loss is reduce. Axial ratio and radiation pattern is also improved. By the use of slot microstrip antenna can be used in many application. A Low Profile Multi-band U-shaped Aperture-coupled Microstrip ...
Effect of the Different Shapes: Aperture Coupled Microstrip Slot Antenna Zarreen Aijaz1 & S.C.Shrivastava2 1,2Department of Electronics and Communications, MANIT, Bhopal, India Abstract: The paper reviews the effect of the different shapes on the aperture coupled microstrip slot antenna.
Abstract: Slot-coupled microstrip patch arrays fed by rectangular overmoded cavities are described and their radiation characteristics analysed using simplified cavity models both for the illuminating and patch resonant cavities. In particular, 4/spl times/4 single cavity-fed and 8/spl times/8 stepped cavity-fed patch arrays were built and studied. US6492947B2 - Stripline fed aperture coupled microstrip ... The microstrip. patch antenna 22 is supported above aperture coupled slot 38 by dielectric material 24. This would typically be a printed circuit board onto which antenna 22 was etched. Energy is electromagnetically coupled from aperture coupled slot 38 to antenna 22 , and, antenna 22 subsequently couples through radiation. 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.
