Abstract
This paper presents a Low-profile slot meander patch antennas. The antenna is a multiple communication bands for handheld devices and implements multiple-input–multiple-output (MIMO) technique. The proposed model covers LTE band-11 1.5 GHz Lower (1427.9 - 1452.9, 1475.9 - 1500.9), LTE band-2 PCS 1900 (1930 -1990, 1850 -1910), LTE band-7 2.6 GHz (2620-2690, 2500- 2570), and LTE band-22 3.5 GHz (3510-3590, 3410-3490) with dB matching criterion (VSWR 3:1). An isolation less than -15 dB has been obtained between two typical slot meander patch antennas. The isolation is achieved as a result of using CPW feeding mechanism and inserted CLL network isolator. This dual-feed (2-elements) planar antenna is fabricated and measured. The result of this small size structured MIMO antenna system shows a good radiation characteristics and small mutual coupling which is promising for MIMO applications in compact portable devices.
