I have designed a folded-shot fractal antenna with single iteration with help of Koch iteration technique to achieve multiband properties. Antenna simulation tool Ansoft HFSS is used to design and simulate. Antenna proposed by me work with six frequency bands with acceptable return loss. Implementation of Folded slot antenna is done over a single slot antenna. Proposed design of antenna offers ...
A dual microstrip meander slot antenna is presented for Wireless Local Area Network (WLAN) application. The proposed antenna comprises a rectangular microstrip patch element embedded with two meander slots. The parametric study is performed to investigate the characteristics of microstrip patch antenna with double meandered slots compared to one without any meander slot. Microstrip patch antenn...
-Wide band truncated rectangular microstrip antenna with H slot loaded and defected ground plane structure is presented in this paper to increase the bandwidth. It is found that the impedance bandwidth of a microstrip antenna could be enhanced considerably when a defected ground structure is used .The band width of a truncated rectangular microstrip antenna with H slot is 21.2% whereas after ad...
In this paper, a tapered slot antenna capable of ultra-wideband communication was designed. In the proposed antenna, rectangular slits were inserted to enhance the bandwidth and reduce the area of the antenna. The rectangular slit-inserted tapered slot antenna operated at a bandwidth of 8.45 GHz, and the bandwidth improved upon the basic tapered slot antenna by 4.72 GHz. The radiation pattern o...
In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition) a...
To achieve dual frequency operation for wireless body area network (WBAN) applications, a hybrid dual-band dielectric resonator antenna with serpentine slot fed by a microstrip line is proposed. The proposed antenna structure consists of cylindrical dielectric resonator and serpentine slot resonator. The serpentine slot is etched on the ground plane of the dielectric resonator antenna (DRA). By...
This paper presents the electrically small U-slot loaded circular microstrip patch antenna with Complementary Split Ring Resonator (CSRR). The technique of U slot loading is used for operating antenna in dual band and CSRR technique to make antenna compact and CSRR for compactness is used. The simple circular patch antenna resonates at 5. 71 GHz with return loss of -11. 38 dB. The proposed ante...
A uniformly spaced comb taper slot antenna array is proposed for directional ultra-wideband (UWB) applications. The UWB array consists of four identical comb taper slot antennas, a mutistage with four-way microstrip UWB power divider, and four identical coaxial cable lines. A maximum gain of 15.5dBi within the band is obtained when the element separation is properly selected. The uniform spacin...
A novel frequency reconfigurable slot antenna is designed for cognitive radio system. In cognitive radio system the two antennas are required one is a wideband antenna and another is frequency reconfigurable antenna. In this work a frequency reconfigurable slot antenna is designed between the switchable frequency range i.e 7.347.96 GHz at eight different frequency band and capable to operate si...
A Dielectric Resonator loaded Substrate integrated waveguide cavity backed slot antenna (SIDRA) is proposed for two slot polarizations and orientation. A SIW-fed cylindrical DRA using rectangular slot is used for obtaining bandwidth of about 5% at 6.15 GHz. For enhancing bandwidth, a plus shaped slot with bandwidth of about 8.80% and gain of 3.7 dB is proposed. The proposed antenna represents S...
