been a major demerit of the microstrip patch antenna , for the remedial action of narrow bandwidth demerit, has directed many of the researchers have directed towards other approach such as meandering and some useful U- slots . For dual band and multi band operations a critical analysis has been performed on the U-slot patch antennas .
antenna consists of dual arrowhead slot on rectangular patch operating at multi-bands in the range from1.9 to 5.8 GHz..The antenna is probe feeded and it is simulated on IE3D Zeland software.The result of the antenna is analyzed by changing their flair angles (45,60,and 75 degree).
Index Terms: Microstrip antenna, patch antenna, U- slots loaded patch and dual band antenna. 1. INTRODUCTION Microstrip antenna inherently has a low bandwidth that limits its application in practice. Several approaches have been made to improve the bandwidth of the single layer patch antenna, such as use of a thick or foam substrate [1-2].

dual-band slot antenna. It is clearly indicated that the proposed antenna has a dual-band characteristic. The simulated result shows that the low-band resonant frequency locates at about 2.4GHz, with the −10dB impedance bandwidth from about 2.3GHz to 2.6GHz, covering the whole 2.4GHz ISM band (2.4–2.485GHz). The high-
3. MODIFICATIONS OF ANTENNA STRUCTURE FOR DUAL BAND The dual band microstrip antenna (MSA) is realized by cutting the slots of different shapes like, U-slot, V-slot, pair of rectangular slots and step slots, etc [9–13]. The geometry of dual band rectangular microstrip antenna is shown in fig 3. It

The standard rectangular microstrip patch is a narrowband antenna and provides 6-8 dBi Gain with linear polarization.
In the process, the single wide response has been split into multiple narrow best online casino for us players no deposit regions catering to specific bands in the WiMAX standard.
These patch antennas have been probe-fed.
Building the Single U-Slot Patch Define Parameters The basic U-slot patch antenna consists of a rectangular patch slots and bingo within which a U-shaped slot has been cut out.
The presence of the slot structure achieves additional capacitance within the structure which combines with the inductance of the long probe feed to create a double resonance within the band.
Boolean subtraction operation is used among the shape primitives for this purpose.
The groundplane in this case is rectangular and 71 mm x 52 mm in size.
Rectangle 'Length',Lgp, 'Width',Wgp ; Define stack Use the pcbStack to define the metal and dielectric layers and the feed for the single U-slot patch antenna.
The layers are defined top-down.
In this case, the top-most layer is a metal layer defined by the U-slot patch shape.
The second layer is a dielectric material, air in this case, and the third layer is the metal ground plane.
Compute and plot the reflection coefficient for this antenna over the band.
The reflection coefficient is plotted with a reference impedance of 50 ohms.
To do so the existing slot parameters are adjusted and a second slot is introduced into the structure.
Create Double U-slot radiator As before use the shape primitives, to create the geometry by using Boolean operations.
Mesh and Plot Reflection Coefficient Mesh the structure at the highest frequency of operation and calculate the reflection coefficient.
Triple-Band U-slot Patch Antenna Parameters For triple-band operation a third U-slot is introduced and the existing slot parameters are adjusted.
