A Low Profile Four-Way Directional Antenna with Dual Polarization
This paper presents a low profile dual polarized directional antenna composed of loop and dipole arrays mounted on a ground plane with each loops and dipoles being fed independently. Each loop antenna is paired with a reflector while each dipole antenna is paired with a director and a reflector. The proposed antenna is intended for an indoor base station (BS) with resonance frequency of 2.4 GHz...
متن کاملA Low-Profile Dual-Polarized Directional Antenna for Enhancing Channel Capacity in Indoor MIMO Systems
Large channel capacity is achieved by MIMO (Multiple-Input Multiple-Output) technology with multi-antenna at the transmitting and receiving side [1]. Many studies to maximize the MIMO channel capacity have been performed, and measurements show that channel capacity is enhanced by directional antennas [2] and multi-polarization [3] in indoor environment. Various MIMO antennas with pattern and po...
متن کاملA Small Low Profile Dual-Polarization Antenna for Indoor MIMO Systems
A pair of small and low profile dual-polarization antennas has been developed for miniature indoor base station under the MIMO (Multiple-Input Multiple-Output) technology to restrain spatial correlation in LOS (Line-Of-Sight) channel environment. Both of the component antennas operate at 2GHz, it is expected to apply on IMT-2000 or LTE communication systems. The space volume is about W150×H120×...
متن کاملTheoretical Analysis of Polarization Rotation angle in Dual Reflector Antenna
Because of special structure, a dual reflector antenna has beam rotation capability in azimuth and elevation directions. In this structure, the antenna beam can be placed in any point in the space by mechanical movement of twist reflector which it is the most important ability of the antenna. Due to the antenna structure, if the polarization of incident wave is linear, it is expected that the p...
متن کاملLow Profile Dual Spiral-Loop Antenna over Electromagnetic Band-gap Ground Plane for Circular Polarization
Electromagnetic band-gap (EBG) structures exhibit unique electromagnetic properties that have led to a wide range of applications in antenna and propagation fields [1], [2]. There are two major advantages associated with EBG ground planes. First, such structures exhibit the possibility of creating a perfect magnetic conductor (PMC) because of their in-phase reflection phase characteristics. Thi...
