A wideband antenna with dual band characteristic at 5.33/14.3 GHz resonating frequencies for wireless applications is presented. The strategy of the design to introduce multiband in band. Band width increases by embedding annular ring on radiating patch and four bands are achieved introducing coupling gap between patches. Surface current distribution analyzed different understanding radiation m...

A new wideband dual-polarized patch antenna consisting of a magnetically-fed and an electrically-fed is presented in the paper. The two feeds are orthogonal to each other at the center of the ground plane and generate 0◦ and 90◦ polarization separately. Two pairs of L-shaped slots are etched in the radiating patch to improve the impedance bandwidth. By using a shorting pin connecting the radiat...

In this paper, a compact, planar ultrawideband (UWB) monopole microstrip antenna is proposed which offers dual band notch characteristics with enhanced rejection at frequency bands centered at 3.4GHz and 5.5GHz. To realize enhanced band notched characteristics at 3.4GHz, a pair of filters is incorporated which includes an inverted ‘L’ shaped slot and a twisted ‘J’ shaped slot in the patch eleme...

The designs of dual band microstrip patch antennas because of their multi-functionality are becoming popular. Satellite mobile and fixed communication for Space Research, Met. Satellite, Radiolocation, Meteorological aids, aeronautical Radio navigation data and analysis has got lot of attentions in the recent years. Achieving selected multiband operation requires precise bandwidth and mutually ...

it is shown how the radiation characteristic of a patch antenna can be manipulated by a small number of normally magnetized ferrite disks inserted in the resonant region of the patch. It is shown that a oneand dual-band circular polarized microstrip antenna can be obtained by taking advantage of the interaction of the antenna cavity field with the magnetized ferrite disks. . The dependence of t...

Microstrip patch antenna has been designed and developed for Unmanned Aerial Vehicle based Synthetic Aperture Radar (UAVSAR). This antenna operates in C-Band at the frequency of 5.3GHz with a bandwidth of 80MHz. The radiation patterns of the antenna were specified to provide a desired scanned area for UAVSAR. The UAVSAR antenna was designed in the form of combination of 3 subpanels to allow dua...

This paper presents a dual band aperture coupled stacked microstrip antenna with the introduction of an air gap 3 mm between the ground plane and the upper layer substrate for WLAN applications. The nominal antenna has – 10 dB return loss bandwidth of 134.8 MHz and 384.9 MHz at lower band resonant frequency of 3.905 GHz and upper band resonant frequency of 5.36 GHz respectively. The gain of the...

This paper presents a novel design of a stacked patch tripleband antenna in both circular and linear polarizations that can be used in a handheld terminal for surveying and geoinformatics applications. The inculcation of corner truncation and I-slot in both the lower and middle patches has achieved better impedance bandwidth and axial ratio at GPS L1, L2 and GSM 1800 resonant frequency bands. A...

A Circular Microstrip Antenna with slot cut in it for tunable and dual band operation has been presented. The existence of an electrically small slot along the feed axis or the perpendicular axis changes the resonant frequency of the patch leading to tunability. If both slots co-exist and are of comparable lengths, which equals to greater than half of the radius, dual frequency operation is obt...
