EFFECTS OF SLOTS ON MICROSTRIP PATCH ANTENNA
Effect of Reflecting Sheet on the Back of Probe fed Slotted ... The effect of placing a conducting reflecting sheet at the back of ultra wideband slotted hexagonal patch antenna for wireless application is presented here. The UWB slotted hexagonal patch antenna without reflecting sheet at the back showed omni directional radiation pattern and good impedance matching criteria. Slot Antenna - an overview | ScienceDirect Topics The slot antenna, consisting of a narrow slit in a ground plane, is a very versatile antenna. With modification, it is amenable to waveguide, coplanar waveguide (CPW), coaxial, slot line, or microstrip feeding schemes and has been used in all aspects of wireless and radar applications.

A bidirectional printed antenna includes a dielectric substrate (33) having first and second surfaces which are substantially in parallel, at least one pair of radiation element conductors (31, 32) having the same shape and the same size … Performance Enhancement of Pentagonal Patch Microstrip-FED… The analysis is performed and results are obtained using Ansoft HFSS. Various parameters which include impedance bandwidth, gain, efficiency, radiation pattern, current distribution of the antenna are studied. Design of dual and Wideband Rectangular Patch Antenna for C and… For that, a rectangular patch antenna with 16×18×1.6 mm3 dimensions with dual-band characteristics, was designed, fabricated and characterized. US20090058731A1 - Dual Band Stacked Patch Antenna - Google… One or more of the embodiments of a dual band stacked patch antenna described herein employ an integrated arrangement of a global positioning system (GPS) antenna and a satellite digital audio radio service (Sdars) antenna.
Effect of Capacitive loading on slot loaded Dual Band ... location of the slots with respect to the patch is defined by the quantities w and l which are very small with respect to the dimensions L and W of the patch. The antenna may be fed with either an aperture or a probe feed [1]. Fig 3 top & side view of designed antenna with parallel slots Authors have c probe feeding. On the Use of Slots in the Design of Patch Antennas The methods developed for efficient wideband patch antenna design are based on one or more of the following principles: A. Thick substrates of low permittivity are used. B. A scheme is devised to reduce the mismatch problem associated ... The U-slot patch (Huynh and Lee, ...
