─ A simple and compact microstrip-fed ultra wideband (UWB) slot antenna with dual band-notch characteristic for UWB applications has been presented. In order to increase the impedance bandwidth of the square slot antenna, we insert a T-shaped slot in the ground plane that with this structure UWB frequency range can be achieved. Additionally, by using a pair of Lshaped slits at the square radiat...

This paper presents a broad-band spatial powercombining system based on tapered-slot antenna arrays integrated in a standard WR-90 waveguide environment. The system is designed using a modular tray architecture, providing full waveguide-band frequency coverage and an excellent thermal environment for a set of monolithic-microwave integrated-circuit (MMIC) amplifiers. The shape of the tapered-sl...

In this paper, we present a miniaturized, Ultra Wide Band (UWB) elliptical slot antenna with a circular stub as a tuning element printed on a FR4 substrate with a dielectric constant of 4.4 operating in the frequency range from 2 GHz up to 14 GHz over which the return loss below -10 dB. The antenna is intended to operate in a system designed to assist the visually impaired in indoor navigation ...

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 ...

With the advanced communications systems, integration of 5G bands, including sub-6-GHz and millimeter-wave (mm-wave) bands with existing lower 3G/4G has become an essential need for future mobile handsets. This article proposes between a large-frequency-ratio dual-band tapered slot antenna multisection meander monopole on handset board. The Vivaldi (TSVA) functions as resonant open-ended at low...

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...
