High‐gain 2 × 2 UWB antenna array with integrated phase inverter

Abstract

A compact 2 × 2 ultra wideband (UWB) antenna array, composed of four planar rectangular monopoles, with a novel feeding network scheme is presented. The feeding network contains a power divider with a wideband balun and a 180°phase inverter in order to add the radiated electric fields of the array elements in-phase. A partial ground plane is used to achieve ultra wide bandwidth. The antenna array has a measured impedance bandwidth from 2.5 to 5.5 GHz with broadside radiation pattern and a measured peak gain of 13 dBi. The proposed array is suitable for portable UWB systems.

The analysis of the different modeling in CST for predicting designs of a monostatic and bistatic RCS

“…In my next scientific work, we intend to research different types of antennas and carry out practical work related to this scientific work. [6]…”

“…The difference in the comparison of the energy thickness goes back to the radar receiver to the energy thickness event on the aircraft and any vehicles. The RCS is contingent on four factors primarily dependent on the material's shape and substance, the monitoring system's orientation, the orientation of the reflected signal, and the electromagnetic signal's wavelength [3][4][5][6].…”

“…So, the scanning radar cannot to get this power. That is for that reason there are bistatic radars, where the emitter and the receivers are spatially separated [5][6][7].…”

Differentially Fed Dual Band Directional Monopole Antenna Array for Wireless Communication

“…Gain enhancement of planar antennas has been reported in several previous works by employing shorting pins [13], artifical magnetic conductor (AMC) structure [14], H-shaped resonator [15] and integrated phase inverter with back-side reflector [16], [17].…”
