“…For a frequencyreconfigurable monopole antenna with three switchable operating modes: UWB, band-notched UWB and dual band radiator, the reconfigurability for the three radiating modes is achieved by controlling the bias voltage of p-i-n diodes and single antenna can be exploited for the three operating modes without changing the physical dimensions of the structure [5][6][7][8] and the reconfigurability of a planar monopole antenna with triple notched band in the band between 3.1 GHz to 10.6 GHz is achieved using two Cshaped slot and a rectangular slot (open-ended quarter-wavelength slot) to filter the frequency bands in the ultra-wide band [9][10][11][12]. To achieve reconfigurable band-notch characteristics the two switches are used in main radiators to activate/deactivate the slots on them, providing reconfigurable band-notch characteristics for WLAN [13][14][15][16]. To miniaturize and achieve reconfigurability, PIN/varactor diodes are introduced in the design.…”

A compact coplanar waveguide fed reconfigurable antenna with three notch bands are presented in this paper. Proposed antenna reconfigurability is acquired by placing bar6404 PIN diodes in the S-shaped ground plane in right to left mode and left to right mode. By switching the diode, reconfigurability achieved for three different operations. The substrate material for the proposed antenna is FR4 with dielectric constant 4.4 and loss tangent 0.02. The overall dimension of the reconfigurable antenna is around 30×26mm2. It is being observed in this work for the cause of each individual slot on notch band characteristics. The measured gain for the designed reconfigurable antenna is quite stable at operating frequencies except notch bands. The proposed antenna is suitable for practical wideband applications with notching.

“…A compact size multiband meta material-based antenna with circular polarization property is proposed in [13] in which the antenna operates at Bluetooth (2400 to 2484 MHz), Wi-Max, and c-band (4-8 GHz). Linear to circular polarization conversion with wide band and wide-angle performances was presented in [14] with the help of multiband reflection mode linear to circular converters. Three single fed circularly polarized square patch antenna structure for wireless applications was proposed in [15] in which the antenna resonates from 1.5 to 1.8 GHz by covering L-Band GPS and GSM 1800 band.…”

A compact circularly polarized antenna having x-slot in the parasitic patches have been proposed in this article. Four driven patches which are capacitively loaded with the help of the feeding loop and four parasitic patches which generate circular polarization because of the sequentially rotated structures are noticed in the proposed modal. With combination of the CP mode with the feeding loop we can observe the broadened axial ratio bandwidth. Comparative analysis has been observed for each side facing driven elements and side and edge facing parasitic elements with X-slot have been observed. The proposed antenna works at the bands of 5.04-5.83GHz and 6.34-6. 81GHz which works for WLAN application. The proposed modal and its iterations have been analyzed using ANSYS EM Software. The results show an enhanced impedance bandwidth of 22 percent and axial ratio bandwidth of over 15percent has been noticed in the proposed modal. A constant gain has been noticed all over the analyzed modals.
