NEW COMPACT HIGH GAIN RADIATING ELEMENT FOR BASE STATION ANTENNA

Design and Analysis of Compact 108 Element Multimode Antenna Array for Massive MIMO Base Station

In this paper, we report the design and evaluation of a compact 108-element base station antenna array for massive multi-input multi-output (MIMO) system using a 3-port multimode antenna as a unit element. Of these three ports, port 1 and port 2 have orthogonally polarized broadside radiation pattern with measured peak gain of 6.5 dBi and impedance bandwidth of 254MHz (2.268GHz– 2.522GHz) and 2...

High Capacity Adaptive Base-station Antenna Systems

The deployment of cellular systems is a success and as the number of subscribers grows, service providers may experience capacity problems due to limited frequency spectrum. Consequently, service providers need to find methods to enhance the coverage and capacity of their networks. Today’s systems are optimally designed for supporting speech traffic in circuit-switched services. The introductio...

Polarization Diversity Gain and Base Station Antenna Characteristics

Dual polarized antennas are traditionally characterized in terms of port-to-port isolation and coand cross-polar radiation patterns. In this paper we instead identify the critical parameter when the antenna is used as a sensor in a polarization diversity reception system. This turns out to be the fareld coupling between the two channels. We calculate the antenna output power correlation and div...

High Gain Mobile Base Station Antenna Using Curved Woodpile EBG Technique

This paper presents the gain improvement of a sector antenna for mobile phone base station by using the new technique to enhance its gain for microstrip antenna (MSA) array without construction enlargement. The curved woodpile Electromagnetic Band Gap (EBG) has been utilized to improve the gain instead. The advantages of this proposed antenna are reducing the length of MSAs array but providing ...
