Antenna Array Construction on a Mobile Terminal Chassis at 3.5 GHz for LTE Advanced

Publication: Research - peer-reviewConference article in Journal

Abstract

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 and the maximum gain
is high are combined into an array. The performance is verified
by comparing performance of the one antenna element to the
performance of the constructed arrays. The proposed method
works both in free space and in data mode for two types of
antenna elements. The method shown that a maximum gain of
the constructed array is 1 to 2.5 dB higher then the gain of a
single element both in free space and in data mode.
