A new patch antenna is analysed which provides dual-frequency operation by means of two narrow slots close to the patch radiating edges. The two modes of operations show similar radiating properties. The ratio between the two frequencies can be well controlled within a range varying from 1.6 to 2, by using simple semi-empirical formulas derived from a physical model and tested by using a ...

Compact dual band slotted patch antenna for wireless systems
The slot loaded patch antenna resonates at 2.43GHz and 3.5GHz frequencies. It has been developed to be used in future WLAN/WiMax technologies. The proposed antenna is simulated using Computer Simulation Technology (CST) microwave studio. The simulated results show that the designed patch... Report "Dual U-Slot Loaded Patch Antenna with a Modified… Dual-Band Circularly Polarized Rotated Patch Antenna With a ...Dual U-slot is incorporated in the radiating patch such that one U-slot is lying within another U- slot forming dual U-slot loaded patchV. CONCLUSION A dual U-slot loaded patch with a modified L-strip feeding technique is presented. PIER Online - A Dual-Band Circularly Polarized Stub … For dual frequency operation, four slots are etched near edges of the patch and a crossed slot etched in the center for generating circular polarization. In order to reducing the frequency ratio of two frequency bands of the antenna, the patch is loaded by four short circuit microstrip stubs. Analysis of L-Slot Loaded Rectangular Patch Antenna for …

Recently, several designs of the dual-band slot-loaded microstrip antennas have been reported [7{9]. These related dual-band designs are achieved by embedding a narrow arc-shaped slot or placing an open-ring slot close to the boundary of the patch [10,11]. Analysis of W-slot loaded patch antenna for dualband ... Number of papers have been reported for dual-band operation such as probe feed U-slot loaded patch antenna , notch loaded patch antenna , shorting pin using E-shaped patch antenna , L-shaped patch antenna , H-shape stacked patch antenna , shorting pin loaded compact antenna , C-shaped microstrip antenna and F-shaped patch antenna .
