A WIDEBAND OMNIDIRECTIONAL PRINTED ARRAY ANTENNA

Optimization of a Wideband Tapped-Delay Line Array Antenna

In this paper, an optimal approach to design wideband tapped-delay line (TDL) array antenna is proposed. This approach lets us control the array angular and frequency response over a wide frequency band. To this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. The optimal weights of the TDL proce...

A Novel Ultra-Wideband Printed Monopole Antenna

In this paper, we introduce a novel printed monopole antenna for ultra-wideband (UWB) applications. The antenna is composed of two overlapped circular disc monopoles with a finite ground plane and fed by a 50 microstrip line. The designed antenna operates over impedance bandwidth (2.9 to 11.6GHz) for return loss S Ω 11 < -10dB. The antenna also shows omni-directional radiation patterns and good...

Design and Implementation of a Compact Super-Wideband Printed Antipodal Antenna Using Fractal Elements

A compact printed fractal antipodal bow-tie antenna is designed and implemented to simultaneously cover the operations in the C, X, and Ku-bands. It is demonstrated that by addition of small fractal elements at the sides of hexagonal arms of the bow-tie, a wide operating frequency range of 3.3 to 19.1 GHz can be covered while antenna size is only 30×34×1.2 mm3. In order to match the antenna to ...

Printed Wideband Antenna for Millimeter Wave Applications

Printed Monopole Antenna Technology for Wideband Applications

Broadband planar monopole antennas have attracted their candidature for wideband applications like WLAN, WiMAX, RADAR, Satellite etc. Eventhough planar monopole antennas have several advantages in terms of cost, compactness, conformality, simplicity they suffer from a major disadvantage of having very narrow bandwidth. Various planar configurations such as circular, triangular, rectangular, hex...
