A compact planar frequency reconfigurable dual‐band multiple‐input‐multiple‐output (MIMO) antenna with high isolation and pattern/polarization diversity characteristics is presented in this article for WiFi and WiMAX standards. The MIMO configuration incorporates two symmetrically placed identical antenna elements and covers overall size of 24 mm × 24 mm × 0.762 mm. Reconfiguration of each antenna element is achieved by using a PIN diode which allows antennas to switch from state‐1 (2.3‐2.4 GHz and 4.6‐5.5 GHz) to state‐2 (3.3‐3.5 GHz and 4.6‐5.5 GHz). In state‐1, the configuration offers isolation ≥18 dB and 20 dB in lower band (LB) and upper band (UB) respectively; whereas, in state‐2, isolation ≥21 dB and 20 dB in LB and UB respectively is achieved. The same decoupling circuit provides high isolation in dual‐band of two states, which makes overall size of the proposed design further compact. The antennas are characterized in terms of envelope correlation coefficient, radiation pattern, gain, and efficiency. From measured and simulated results, it is verified that the proposed frequency reconfigurable dual‐band multi‐standard MIMO antenna design shows desirable performance in both operating bands of each state and compact size of the design makes it suitable for small form factor devices used in future wireless communication systems.

“…Lumped network [11] and resonator decoupling network [12] are applied to increase isolation. A Y-shaped isolator [13] is introduced to decrease mutual coupling between dualelement antennas. In [14], a split ring decoupling structure realizing hybrid electric and magnetic coupling is adopted for isolation enhancement.…”

“…In this letter, the proposed MIMO antenna consists of two symmetrical antenna elements arranged with edge-to-edge distance of 5.3 mm (0.044λ at 2.51 GHz), which is the smallest among those dual-band MIMO antennas [5,13,[15][16][17]. The decoupling structure in this paper constructs an extra coupling path to offset the original coupling.…”

Abstract-A dual-band two-element Multiple-Input-Multiple-Output (MIMO) antenna for Wireless Local Area Network (WLAN) applications is proposed in this paper. The MIMO antenna consists of two closely arranged symmetric monopole antennas with edge-to-edge distance of only 5.3 mm (0.044λ at 2.51 GHz). To enhance isolation, a decoupling network is inserted between the two antennas without increasing the footprint. The −10 dB impedance bandwidths in lower and higher frequency bands are 2.46-2.7 GHz and 5.04-5.5 GHz. Compared to previous works, the presented decoupling structure can obtain higher isolation over 30 dB in dual bands. Measured results agree well with the simulated ones.

A small wideband Y-shaped antenna is presented in this paper. A monopole of Y-shaped with two rectangular-shape frequency shifting strip is used to produce a compact dimension of 10 mm Â 12 mm on a 1-mm-thick FR4 substrate. The antenna has an impedance bandwidth (measured below À10 dB from 39.57 to 44.63 GHz), a gain more than 4.9 dB, radiation efficiency of 81%, and voltage standing wave ratio (VSWR) < 2, within the bandwidth of interest, making it a viable option for 5G applications.
