چکیده

A low-profile wideband tri-polarized multi-input multi-output (MIMO) antenna is proposed in this communication. Based on characteristic mode analysis (CMA) of a circular patch, four slots are etched symmetrically the patch to transform high-order monopole-like modes into broadside with lower resonant frequencies. Four sets shorting pins also applied simultaneously adjust frequencies and fundamental patch. The effects these analyzed detail. Three dual-resonance ports high isolation achieved by exciting three pairs orthogonal respect its profile (bandwidth/height = 216), as facilitated property each port. Experimental results show that features port (>35 dB) gain (>5.58 dB). tri-port can be highly integrated MIMO systems.

A Novel Low-profile Wideband Uhf Antenna

Abstract—In this paper, an ultra high frequency (UHF) low-profile antenna is proposed; it is based on the discone antenna but with addition of a back cavity, a short-circuiting structure and a two-plate top structure in order to achieve both low-profile and wideband. It is simulated and prototyped. The test results show that the antenna has an omni-directional radiation pattern in the horizonta...

A 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...

Low-Profile Wideband Circularly Polarized Patch Antenna Using Asymmetric Feeding

A low-profile wideband circularly polarized aperture stacked patch (ASP) antenna without air dielectric layers is presented. The new circular ASP antenna, which is fed by two orthogonal dual-offset lines through an asymmetric crossed slot, delivers a wide bandwidth of 80% for the 10-dB return loss and similar input impedance characteristics for the two ports. Then, a novel broadband 90◦ hybrid ...
