“…There is a growing interest in using this type of reconfiguration combination and a number of designs have been proposed [70]. One important method makes use of an active electromagnetic band gap (EBG) or metasurface structure along with switches on top of the antenna resonator [69][70][71][72]. However, most common is the integration of methods for achieving frequency and polarization reconfigurability using active elements such as varactor diodes and PIN diodes, in addition to some other modifications [73][74][75][76].…”

“…By adjusting the positions between the center of the slot radiator and the metasurface, frequencies from 8.0-11.2 GHz and polarization states LP, LHCP, and RHCP could be chosen. A square ring antenna patch antenna with two horizontal gaps [72] provided LP at 2.4 and 4.18 GHz, and LHPC and RHCP characteristics at 3.4 GHz. A square-ring patch radiator cut in the ground plane has a vertical gap across which two PIN diodes bridge.…”

Reconfigurable antennas play important roles in smart and adaptive systems and are the subject of many research studies. They offer several advantages such as multifunctional capabilities, minimized volume requirements, low front-end processing efforts with no need for a filtering element, good isolation, and sufficient out-of-band rejection; these make them well suited for use in wireless applications such as fourth generation (4G) and fifth generation (5G) mobile terminals. With the use of active materials such as microelectromechanical systems (MEMS), varactor or p-i-n (PIN) diodes, an antenna’s characteristics can be changed through altering the current flow on the antenna structure. If an antenna is to be reconfigurable into many different states, it needs to have an adequate number of active elements. However, a large number of high-quality active elements increases cost, and necessitates complex biasing networks and control circuitry. We review some recently proposed reconfigurable antenna designs suitable for use in wireless communications such as cognitive-ratio (CR), multiple-input multiple-output (MIMO), ultra-wideband (UWB), and 4G/5G mobile terminals. Several examples of antennas with different reconfigurability functions are analyzed and their performances are compared. Characteristics and fundamental properties of reconfigurable antennas with single and multiple reconfigurability modes are investigated.

“…, four PIN diodes are used to control the radiation direction by selecting the appropriate radiator using diodes ‘ON’ and ‘OFF’ modes. Moreover PIN diodes have been used to achieve pattern reconfigurability, polarization, and frequency reconfigurability . In all the references discussed above, either a multiband operation is achieved or single band frequency reconfigurability is achieved.…”

This paper presents the implementation of open complimentary split ring resonator (OCSRR) structure in small rectangular radiating elements to achieve triple band and dual band reconfigurability using PIN diode. The proposed design is a coplanar waveguide fed structure and consists of three small radiating elements, whereas two OCSRR structures are coupled with the two‐radiating elements. The third radiating element embedded with OCSRR is connected using a PIN diode. Under DC biasing conditions the whole design resonates at three frequencies, that is, 1.9, 3.8, and 5.5 normalGnormalHnormalz, whereas the proposed design switches to dual band operation at 2.6 and 5.5 normalGnormalHnormalz in the diode ‘OFF’ state. The proposed structure is designed and fabricated on a single sided ungrounded FR 4 substrate. Overall, a good agreement between simulated and measured results is observed. It is also observed that the radiation patterns of the proposed antenna are the same with gains of 4.5, 3.2, and 2.5 normaldnormalBnormali at 1.9, 3.8, and 5.5 normalGnormalHnormalz in the PIN diode ‘ON’ state, respectively, whereas in the diode ‘OFF’ state, at 2.6 normalGnormalHnormalz the gain is 4 normaldnormalBnormali and at 5.5 normalGnormalHnormalz the gain is 2.5 normaldnormalBnormali.
