Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. Introduction: At microwave and millimeter wave frequencies microstrip slot antenna (1) becomes very small & lightweight. In spite of these advantages, it has main disadvantage of back radiation; which limits its use in mobile communication. US20110006950A1 - Microstrip antenna comprised of two slots ... Disclosed relates to a microstrip antenna, particularly, relates to a dual band microstrip antenna including two slots. The microstrip antenna includes a conductor plate having a first hole and a substrate having a microstrip patch where slots of two different sizes are positioned, the substrate being located on a top of the conductor plate. Gain and Bandwidth Enhancement Techniques in Microstrip Patch ... antennas e.g. probe fed stacked antenna, microstrip patch antennas on electrically thick substrate, slotted patch antenna, air gap, parasitic patch and stacked shorted patch have been proposed and investigated [8-9]. Recently defective ground structure is introduced, that includes advantages such as Dual Frequency Hexagonal Microstrip Patch Antenna

Fig 3 shows the return loss for the single u-slot antenna which is the simulated result. From the Fig 3, it can be shown that the U-slot microstrip patch antenna at 5.5GHz results in the broadening the bandwidth of the antenna. The graph is plotted for frequency in GHz versus return loss in dB. A Review on Circular Microstrip Patch Antenna with Slots A Review on Circular Microstrip Patch Antenna with Slots for C Band Applications . Nidhi M. Thaker, Vivek Ramamoorthy . Abstract — Over the past one decade, there is a rapid growth in development of various applications involving wireless communication. EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA This paper presents effect of slots on microstrip patch antenna and its parameters. The effect is shown on bandwidth, gain, radiation pattern, return loss, axial ratio and size of an antenna. The slots on the patch or on the ground plane will help to design a antenna with improved bandwidth and effeciency. How slots are cut on a microstrip patch antenna. is there

For that, a rectangular patch antenna with 16×18×1.6 mm3 dimensions with dual-band characteristics, was designed, fabricated and characterized.
Design And Analysis Of Compact U Slot Microstrip Patch Antenna 11 The Voltage Standing Wave Ratio or VSWR is defined as the relation between the maximum voltage and the minimum voltage all along the transmission line. Further definition of the VSWR can be derived from the level of forward and reflected waves,
Design & Performance Analysis of Double U-Slot Microstrip ... The designed patch antenna with double u-slot had been given below figure Figure 4: design structure of the single u-slot patch antenna III. RESULTS A.Return loss characteristics For Single U-Slot Figure 5: Return losses for single U microstrip antenna -Slot The equations which is applicable to above is same for this type antenna is Figure 6 ... Effect of slots on microstrip patch antenna characteristics - IEEE Xplore Abstract: In this paper, a novel design approach of microstrip patch antenna is presented. The antenna consists of slotted conducting patch element with air filled ... Design of microstrip patch antenna with multiple slots for satellite ... In this paper, a microstrip patch antenna is proposed for satellite applications and it is designed at 15 GHz with multiple slots on the rectangular patch. MULTI-SLOTTED MICROSTRIP PATCH ANTENNA FOR WIRELESS ...
Keywords: Microstrip Patch Antenna, Ultra wide band antennas, Return loss, slots.In this work, a rectangular patch with slots is selected for the analysis. Although the transmission line model yields less accurate results, it is a very simple model and provides a good physical insight of the basic...
circular microstrip patch antenna with different slot for the W L A N & B l u e t o o t h Application is presented.The shape of proposed antenna is circular.The operating frequency of antenna is 1.5-2.5 GHz, The antenna design consists of a single layer of substrate with thickness 1.6 mm with dielectric On the Use of Slots in the Design of Patch Antennas experimental study of the geometry shown in Fig.2.6. A patch antenna with a parasitic patch is sometimes known as an electromagnetically coupled patch antenna. The experiment was performed at NASA Lewis Research Center (later renamed Glenn Research Center) by my MS student J. Bobinchak, in collaboration with Dr. R. Q. Lee of NASA. A Review on Circular Microstrip Patch Antenna with Slots ... A Review on Circular Microstrip Patch Antenna with Slots for C Band Applications. Nidhi M. Thaker, Vivek Ramamoorthy. Abstract — Over the past one decade, there is a rapid growth in development of various applications involving wireless communication. The performance of all such wireless systems depends on the design and proper functioning of ... Microstrip Patch Antennas - University of Texas at El Paso Microstrip Patch Antennas Slide 19 The transmission-line model represents the microstrip antenna by two slots, separated by a low-impedance transmission line of length L. Looking at a cross section of the antenna (x-y plane), this is effectively a non-homogeneous transmission line. Fringing effects make the microstrip line look wider than it is.
