“…However, optical switches have lossy performance and very complex activation procedure. Various semiconductor switches like varactor [29][30][31][32], PIN are usually used in the reconfigurable system because they are a faster and more compact substitute to RF-MEMS [33][34][35][36][37]. The advan-tages of semiconductor switches include fast switching, high isolation, low power consumption, and low operating voltage (0-10 V).…”

Different semiconductor materials have been used for the fabrication of PIN diodes such as Si, Ge, GaAs, SiC-3C, SiC-4H, and InAs. These different semiconductor materials show different characteristics and advantages such as SiC-4H is ultrafast switch. But, when flexible polymers composites like Si-nanomembranes, polyethylene terephthalate (PET), and biodegradable polymer composite like carbon nanotubes (CNT) are used for fabrication, the device has the capability to switch from rigid electronic devices to flexible and wearable electronic devices. These polymer composites’ outstanding characteristics like conductivity, charge selectivity, flexibility, and lightweight make them eligible for their selection in fabrication process for wearable electronics devices. In this article, the performance of PIN diodes (BAR64-02) as an RF switch is investigated from 1 to 10 GHz. PIN diodes can control large amounts of RF power at very low DC voltage, implying their suitability for RF applications. In this paper, the benefit of using plastic polymer composites for the fabrication of PIN diodes, capacitors, and antennas is thoroughly described. Along with this, individual characterization, fabrication, and testing of all biasing components are also done to analyze the individual effect of each biasing component on the performance of PIN diodes. The complete biasing circuitry for the PIN diode is modeled in the HFSS software. When a PIN diode is inserted in between 50 Ω microstrip line, it introduces 1 dB insertion loss and 20 dB isolation loss from 1 to 7 GHz. Finally, a PIN diode is integrated in a reconfigurable antenna to study the actual effect. The transmission loss in the RF signal is nearly 1 dB from 1 to 7 GHz in the presence of biasing components.

“…Different switches are selected depending on the suitable application. For example, a fast and discrete switching response requires PIN diode [34], while a continuous tuning response requires a varactor diode [31]. The PIN diode offers high switching speed (1-100 ns) and high isolation compared to other semiconductor switches.…”

“…As mentioned earlier, due to different positions of switch integration on these slot antennas [18], it is feasible to alter the characteristics of the antenna. This is concluded by adjusting the electrical length of the current flow or control the flow of current distribution around the slot [19–22]. By integrating the actuating circuits in the antenna system, the overall performance of the antenna can be increased.…”

In this paper, non-uniform meandered line shunt capacitive RF-MEMS switch is presented at an elliptical patch etched with a split-ring resonator (SRR) for satellite communication applications. The non-uniform meander line shunt capacitive is a fixed-fixed type of RF-MEMS switch that is introduced in this model antenna. The proposed antenna design is resonated at 10.46 GHz with the return loss of −37.6 dB. The performance evolution of the proposed antenna design is evaluated with and without integrated RF-MEMS switch on the proposed antenna SRR. It is observed that the proposed model at the ON-state switch resonates at 10.57 GHz frequency with the return loss of −30 dB. Similarly, at the OFF-state switch, it resonates at 10.53 GHz frequency with the return loss of −43 dB. Al3N4 (aluminum nitride) is used for the switch as a dielectric material, hence the switch attains higher isolation. The actuation voltage of 7.9 V is required for the switch to actuate from ON to OFF state. The switch attains minimum insertion and return loss which is discussed in further sections. The proposed antenna is fabricated and tested by a vector network analyzer; there is a good agreement between the simulated and measured results.

“…Integrated reconfigurable antenna which provides multiple selectable features meets the above said requirement. In [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], some design schemes are available in which two antennas are integrated on a solitary substrate to optimize the space utilization. In these reported schemes, small antennas are incorporated in huge sized UWB radiator either by reutilization of large printed area of UWB antenna as ground plane for the second antenna [4][5][6][7][8][9] or by placing the small sized antenna in electrically neutral area of UWB antenna [10][11][12][13].…”

“…All these designs are good and solve the problem of underutilization of large printed area of UWB antenna. However in all reported designs, the numbers of reconfigurable features are confined to either frequency reconfiguration or NB-WB reconfiguration [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. However, single reconfiguration feature is not sufficient for future communication devices.…”

A two port, integrated reconfigurable versatile antenna is proposed here. The proposed antenna can reconfigure its frequency, bandwidth, polarization state and radiation pattern and hence is versatile in its characteristics. The antenna is integrated in such a way that the space of one antenna can be used to print two antenna structures to increase the antenna versatility into a small package. PIN diodes are placed in a position so that the electrical switching of the PIN diodes makes every part of the antenna multipurpose. The prototype has been fabricated to authenticate the simulated results. The simulated and measured results are in good agreement. The antenna can be used for Cognitive Radio application.
