Design And Analysis Of Compact U Slot Microstrip Patch Antenna 9 Figure 1: U -Slot loaded rectangular micro strip antenna These properties make FR4_epoxy very attractive to be used as substrates for the fabrication of antennas in applications requiring light weight, low loss, reduced bill of materials, preserving the electromagnetic performance. ANALYSIS OF SLOT COUPLED MICROSTRIP PATCH ANTENNAS A ... microstrip line fed, proximity coupled and slot coupled microstrip patch antennas are provided. Numerical results in the form of current distributions and input impedance are presented and compared with the results given in literature. A microstrip antenna idea was firstly introduced in 1950’s but it became popular and 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.

The Effect of Changing Substrate Material and Thickness on ... In order to design a microstrip patch antenna at first the designer is to select the substrate material and it’s thickness. So, if the designer has a clear conception about the effect of changing substrate material and it’s thickness on the performance of the antenna, it will be easier to design an antenna. 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.
This paper presents the numerical simulation of double U-slots microstrip patch antenna for WiMAX application. The proposed antenna is feed by the Transmission line. The total area occupies by the antenna 40mmx47mm. In this design two slots and one bridge elements have been ap-

Axial Ratio and Gain Enhancement of a Circular-Ring Slot 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.
If both slots co-exist and are of comparable frequency antennas are required. Slot being a lengths, which equals to greater than half of the complementary structure of the stub, cutting radius, dual frequency operation is obtained. Microstrip patch antenna for UHF and microwave RFID
