A dual‐frequency circularly polarized structure antenna

Abstract

A concept of an original compact dual‐band circularly polarized structure antenna is presented. It consists of a dielectric resonator antenna associated with a microstrip one. This antenna has a return‐loss bandwidth superior to 6% for each band, and offers in circular polarization a great axial ratio. Such a structure maybe useful for spatial applications. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 32: 418–420, 2002.

Design and Analysis of High Beam forming MIMO Antenna for 5G Applications

“…By selecting suitable coupling slot and 90 o phase difference with equal amplitudes in the antenna array, we can easily obtain the circular polarization and beam forming [7][8]. Similarly the dual conformal strip [9][10] method is also maintaining circular polarization and cost effective with ease of excitation. To meet the broadband service the bandwidth characteristics [11] and omnidirectional pattern must be improving in the monopole antenna.…”
