In this paper, a new low-profile smart multiple-input multiple-output (MIMO) antenna system is presented for WiFi IEEE 802.11a/b/g/n/ac/ax applications. The proposed compact 2.4-GHz antenna system employs two beam-switching antenna cells for MIMO operation. Each antenna cell is composed of four reconfigurable frequency-selective reflectors (RFSRs) and a one-to-four switching feeding network. The RFSRs are constructed using a one-wavelength metal loop resonator, which functions as a radiating antenna or a wave reflector to reflect beams along a specific direction, as controlled by the switching network. The feeding switching network utilizes PIN diodes to adjust the phase and impedance required for changing the operational status of each RFSR. The overall dimensions of the antenna system, including the metallic ground, are 120 mm ´ 120 mm ´ 9.5 mm. Moreover, the measured operational bandwidth of the 2.4-GHz antenna is approximately 100 MHz, and the radiation efficiency of each directed beam is 40%–70%.

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.
