AbstractCarbon nanotube (CNT) has emerged as potential candidate for replacement of conventional metal patch in antenna application. The principal objective of our research is to develop nanostructured flexible patch antenna array for multi- frequency operation in industrial, scientific and medical (ISM) band. Patch antenna design using CNT on flexible cotton sheets has been simulated with cotton as a substrate and CNT as conductive patch and ground plane. Due to high conformability and conductivity of CNT all antenna parameters like VSWR, return loss, gain and radiation pattern obtained using FEKO EMSS software meet design criteria. Our simulated antenna design shows a return loss less than -10 dB and VSWR less than 2 at 2.06 GHz, 2.38 GHz and 2.49 GHz. We have also simulated a versatile and conformable antenna design where the whole geometry is rolled up like patch array on cylindrical surface. Conformability to curved surfaces and integration with the structure brings about a unique antenna design. An inset fed square patch array is also proposed for RF energy harvesting operating in the 2.45 GHz ISM band that can harvest and store energy from the surrounding environment. Simulation result shows that dc voltage of 0.215 V can be achieved at -6 dbm received energy level at 2.45 GHz IEEE 802.11b band. This would correspond to potential working distance of 10m.

An Ultrawideband (UWB) octagonal ring-shaped parasitic resonator-based patch antenna for microwave imaging applications is presented in this study, which is constructed with a diamond-shaped radiating patch, three octagonal, rectangular slotted ring-shaped parasitic resonator elements, and partial slotting ground plane. The main goals of uses of parasitic ring-shaped elements are improving antenna performance. In the prototype, various kinds of slots on the ground plane were investigated, and especially rectangular slots and irregular zigzag slots are applied to enhance bandwidth, gain, efficiency, and radiation directivity. The optimized size of the antenna is 29 × 24 × 1.5 mm3 by using the FR-4 substrate. The overall results illustrate that the antenna has a bandwidth of 8.7 GHz (2.80–11.50 GHz) for the reflection coefficient S11 < −10 dB with directional radiation pattern. The maximum gain of the proposed prototype is more than 5.7 dBi, and the average efficiency over the radiating bandwidth is 75%.

Circular Patch Antenna

Inefficient utilization of licensed spectrum bands and overcrowding of unlicensed bands are caused due to the spectrum shortage and growing demand for wireless communication. The wireless spectrum is burdened due to the host centric traditional approaches for data detection and recovery in the IP-based networks that. The service or data is retrieved from the service provider through a new routing path every time the mobile service requester initiates a request. The vacant licensed channels are utilized appropriately enabling opportunistic and efficient band usage of the spectrum using Cognitive Radio (CR) technology. Wireless communication with low cost, compact antenna element, high gain, wideband and low profile can be performed using patch antenna. Patch is a significant aspect of antenna design. The antenna design parameters are understood by varying the patch. A good return loss can be achieved by enhancing the radiation pattern on changing the patch dimensions. High Frequency Structure Simulator (HFSS) is used for simulation and analysis of the circular patch antenna. The return loss, radiation efficiency, Voltage Standing Wave Ratio (VSWR) and radiation pattern of the antenna are analyzed.

This paper proposes a reconfigurable microstrip patch antenna design for wireless ISM band applications. The antenna simultaneously uses PIN Diodes to switch between linear and circular polarization at 2.45 GHz and uses Varactor Diode to continuously tune the operating frequency from 1.73 GHz to 2.45 GHz. The antenna performance is characterized as a combination of ON/OFF state of PIN Diode and a bias voltage of Varactor Diode varying from 0.8V to 10V. A good agreement between simulation and measurement is obtained which validates the proposed method. The proposed frequency/polarization reconfigurable antenna is promising for various applications in wireless ISM band such as DCS (1710 – 1880 MHz), PCS (1850 – 1990 MHz), GSM 1800, GSM 1900, UMTS (1920 – 2170 MHz) and WiFi/Bluetooth (2.4 – 2.5 GHz).

This work builds a metamaterial (MTM) superstrate loaded on a patch of microstrip antenna for wireless communications. The MTM superstrate is made up of four G-shaped resonators on FR-4 substrate with a relative permittivity of 4.4 and has a total area of (8×16) mm2, and is higher than the patch. The MTM superstrate increases antenna gain while also raising the input reflection coefficient. When it is 9 mm above the patch, the gain increased from 3.28 dB to 6.02 dB, and when it is 7 mm above the patch, the input reflection coefficient was enhanced from -31.217 dB to -45.8 dB. When the MTM superstrate loaded antenna was compared to the traditional unloaded antenna, it was discovered that metamaterials have a lot of potential for improving antenna performance.

Slot and patch modification for the design of a compact multiband antenna with Multi-Input-Multi-Output (MIMO) functionality is proposed in this paper. At various frequency bands, the antenna performance is obtained by modification and addition of slot and patch shapes in the design of the compact MIMO multiband antenna. Addition of slots or patches is done separately in the already existing multiband antenna designs. Whereas in this work, the addition of slot and patch are combined. Arlon Diclad 880 with a dielectric constant of 2.17 - 2.2 (εr) and height 0.75mm is used for the antenna design. The MIMO multiband antenna with the dimension of 12.5 mm × 7.5 mm is designed. On various millimeter-wave frequency bands ranging from 20 GHz to 40 GHz, the MIMO antenna can function as observed in the results of simulation and evaluation. This work shows that microstrip antennas can be added with slots and patches during their design and development, thereby enabling the antenna to operate under multiple frequency bands.
