This paper proposes a method of constructing an antenna array on the typical ground plane of the modern mobile terminal. An IFA and a slot in a metal frame antenna elements have been used to illustrate the proposed method. The radiation pattern of the element is recorded at the chosen number of the discrete locations on the ground plane. Antenna elements at the positions, where the boresight is similar...
This paper proposes a novel dual‐band in‐phase reflection characteristic high impedance surface (HIS) by using two‐layer edge located vias and interdigital structures (TELI‐HIS). It has simple structure and compact size, and is easy for dual‐frequency tuning. Parametric study and working mechanism of it are presented. Through the destructive interference between the reflected wave produced by the...
In this paper, MIMO reference antennas with different correlation coefficients are proposed for Over-The-Air (OTA) applications. The correlation can be simply controlled through a slot etched on a dual-feed PIFA with the similar total efficiency. Three kinds of situations are investigated with the proposed method: high correlation (HC), mid correlation (MC), and low correlation (LC). In order to verify...

A - mutual scattering mode -is introduced in this paper as a novel method to reduce the correlation for the LTE MIMO antenna arrays. This mode is mainly based on the increase of the Q factor for the closely-positioned MIMO antenna elements. With the increased Q factor, each element becomes a scatter for the other elements. Consequently, without adding any structure in the MIMO system, the radiation...
