High Gain Planar Antenna Structures for Ka-band Applications

Design and Implementation of Quasi Planar Ka Band Array Antenna Based on Travelling Wave Structures

Improvements on a Planar Inverted-F Antenna using Electromagnetic Band-Gap structures

This paper presents the effect of an EBG, Electromagnetic Band-Gap, structure as the ground plane of a PIFA, Planar Inverted-F Antenna. The PIFA is a type of antenna which has been used in many communication applications. It is a medium bandwidth radiator with reduced dimensions. The EBG structures have special electromagnetic properties such as high surface impedance and suppression of propaga...

New Low Cost Printed Antenna CPW-Fed for Global Positioning System, Personal Communication System and Worldwide Interoperability for Microwave Access Band Applications (TECHNICAL NOTE)

This paper presents a new design of a CPW-Fed multi bands planar antenna. This antenna can be integrated easily with passive and active elements. The proposed antenna is suitable to operate for GPS, PCS and WiMAX bands. Its entire area is 52.3x52.6mm2 and is employed on an FR-4 epoxy substrate and fed by a 50 Ohm coplanar line. The antenna parameters have been analyzed and optimized by using AD...

A New Compact Ultra-wideband Linear Antenna Array for Target Detection Applications

This paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (UWB) wireless communication and target detection applications, respectively, operating in the frequency span of 3 GHz to 11 GHz. A prototype was fabricated and then measured based on optimal parameters. The results of reflection coefficient (S11) and radiation patt...

A Multiband Multiple-input Multiple-output Antenna System for Long Term Evolution and Wireless Local Area Networks Handsets

A novel multiband multiple-input-multiple-output (MIMO) antenna system is proposed. The MIMO antenna system consists of two antenna elements, each of which comprises of three radiators: a driven monopole, an S-shaped strip and an inverted F-shaped strip and occupies footprint of 15x18.5x0.8 mm3 only. The driven monopole acts as a quarter-wave monopole and stimulate higher mode resonance. The tw...
