A Coplanar Waveguide Fed ultra wide band (UWB) slotted Hexagonal patch antenna which finds application in wireless communication is presented here. It was designed to operate in the UWB range ( 3.1GHz to 10.60GHz). The antenna presented here is designed on FR4 substrate with loss tangent δ=0.0025 and dielectric constant 4.4. The dimension of the proposed antenna is 34 X 29 X 1.6 mm. The fundame...

A new reduced size single probe fed microstrip patch antenna with irregular slits has been presented to be used as a receiving antenna for Global Positioning Systems (GPS) integrated with cellular handheld mobile wireless systems. The proposed design is based on the nearly square microstrip patch antenna with two pairs of orthogonal slits cut from the edge. It has been found that this antenna o...

according to high costs of phase shifters in antenna arrays, new methods for beam steering without phase shifter were introduced. frequency diverse array (fda) concept is another approach to beam steering problem. in this structure, the subsequent antenna elements are fed with stepped discrete frequencies causing continuous scanning of space in time. so a range-angle dependent scanning is made ...

This paper describes the design of Rectangular Microstrip Patch Antenna with Triangular Slot (RMPATS) at a frequency of f = 2. 4 GHz. The proposed antenna has been designed by introducing a triangular slot in the rectangular patch. The FR4-Epoxy with relative permittivity 4. 4 and height 1. 6 mm is used as substrate material. Antenna is fed by coaxial probe feed. The proposed antenna have accep...

In this paper, the design and analysis of a compact size coplanar waveguide (CPW)-fed antenna for ultrawideband (UWB) applications is presented. The antenna has a compact size of 20×20× 1.5 mm and provides a good impedance matching over the entire bandwidth of 3.2–14.3 GHz. The characteristics parameters, i.e. return loss, VSWR and radiation pattern, are analyzed using HFSS 11.0 software. Keywo...

A micro strip-fed printed bow-tie antenna is presented inorder to achieve wide bandwidth, high gain, and size reduction. A comparisonbetween the bow-tie and the quasi-Yagi (dipole and director)antennas shows that the bow-tie antenna has a wider bandwidth, highergain, lower front-to-back ratio, lower crosspolarization level, andsmaller size. Two-element arrays are designed and their characterist...

The characteristics of a bow-tie slot antenna with tapered tuning stubs fed by a coplanar waveguide (CPW) are investigated. The effects of the antenna dimensional parameters are studied through simulation results and design procedure is developed and verified for different frequency bands. The antenna shows wideband characteristics for radar and wireless communication applications. Numerical si...

This paper presents coaxial feed rectangular microstrip patch antenna. A narrow Lshaped microstrip antenna is fed at the corner using a coaxial feed to obtain a LP operation. Experiments are carriedout to investigate its return loss, its radiation and its time domain behavior, which exhibit good radiation pattern. The simple rectangular and compact L-shaped microstrip antenna is simulated with ...

In this paper, we propose a small switched-beam antenna for mobile terminal. This kind of antenna is a single compact slot antenna fed by microstrip line. This proposed antenna provides three different radiation patterns. The antenna is designed to cover 3G Universal Mobile Telecommunication Systems (UMTS; 1.922.17 GHz). Its advantage is small of size and easy to manufacture. The performance of...

In this paper, we have simulated a single-pin-shorted microstrip line fed three-dielectric-layer (with different permittivity and thickness) rectangular patch microstrip antenna for all those communication systems whose limited antenna size is premium. Low permittivity hard foam has been used as one substrate to achieve wide bandwidth. The simulation of this proposed antenna has been performed ...
