“…Reference [18] describes a compact and novel shaped hexa-band frequency reconfigurable antenna with a very wide tuning band that operates in two single band modes (3.5 and 4.8 GHz) and two dual band modes (i.e., 2.10, 4.15 GHz, and 2.4 and 5.2 GHz). Reference [19] describes a compact monopole antenna that can be reconfigured into seven different single bands, including 1.575, 2.4, 3.5, 5, 5.5, 6, and 9.2 GHz, using a PIN diode. Reference [20] describes a compact multiband reconfigurable PIFA antenna comprised of two p-i-n diodes that can operate in a wide range of wireless communication applications including LTE, GSM, GPS, 3G, WiMAX, and Wi-Fi.…”

This article proposes a novel multifunctional wideband reconfigurable antenna with a frequency selective surface (FSS) reflector to improve gain across all operating bands. Initially, a wideband trapezoidal monopole antenna with a 138% impedance bandwidth (1.53-8.45 GHz) on a FR-4 substrate with a thickness of 0.80 mm and an area of 51 Â 56 mm 2 was designed. In order to achieve multifunctionality, two inverted L structures with two rectangular slots were introduced at the ground plane. Each slot functions as a filter, producing various resonating bands. To obtain the desired resonating frequency bands, the effective length of the slot was changed by strategically placing RF switching element PIN diodes. The proposed reconfigurable antenna can switch between 10 different frequency bands. To improve the gain of the proposed reconfigurable antenna, a novel FSS reflector with a 5 Â 5 array of elements is placed 1.01λ (34.54 mm) below the proposed antenna. The application of the FSS results in a 3-6 dBi improvement in antenna gain, not only for the wideband range, but also for all operating frequency bands. Over the entire operating bandwidth, the radiation efficiency ranges from 93% to 75%. For GPS, RADAR, LTE42/43, WLAN, WiMAX, STM-Link, and UMTS applications, the proposed antenna operates in a wideband state, three single band states, four dual band states, and three tri band states. This work provides more antenna functionality at a lower cost, as well as significantly reduced size and space requirements.The proposed antenna can be easily integrated into portable electronic devices for a variety of wireless applications due to its broad switching capability and unique feasibility.

“…To achieve re-configurability, two microstrip lines parallel to the feeding line and two PIN diodes are employed [16][17]. The use of lumped components such as positive-intrinsic-negative (PIN) diodes allows antennas with reconfigurable structures to be modified, allowing them to adapt to varied frequencies [18][19]. To adjust the resonance frequency, patch antenna slots are provided, and these slots are linked or detached using switches [20].…”

In this paper, A Switchable Filtering Antenna Integrated With U-Shaped Resonators for Bluetooth, WLAN & UWB Applications is presented. To achieve the UWB operation, a rectangular defect on the ground plane and square slots are etched on the rectangular patch. The selectivity of frequency is achieved by integrating a Hairpin filter. Three switches are connected at the corners of the filter to achieve frequency re-configurability. A total of eight Boolean combinations are possible by controlling ON and OFF these switches. This filtering antenna acts as a band pass filter and picks distinct frequency bands within the UWB frequency. It can be used for wireless applications such as Long-Distance Radio Communication, Aviation Services, WLAN, C-band satellite communication, Wi-MAX, mobile satellite sub-band, radar communications, and space communications. In addition, two inverted U- shaped resonators of differing lengths are engraved on the rectangular microstrip patch to operate at Bluetooth frequency applications with frequencies ranging from 2.4 to 2.458GHz. The maximum gain obtained out of all operating frequencies is 4.82dBi at a frequency of 9.5GHz. The proposed antenna is simulated using the 3D-Simulation tool CST MWS. The performance of the designed antenna is estimated using the parameters like return loss, VSWR, and Far-field Gain characteristics.
