This paper introduces a balanced (differential) multiband reconfigurable (tunable) bandstop filter (BSF) using all lumped elements. The main features of the design include its ultra-compact size as well as flexibility to control any frequency band independently in terms of both center frequency and absolute bandwidth (ABW). In the proposed structure, the corresponding non-resonating nodes (NRN) of the symmetrical bisections are connected to N number of LC π-circuits (N-band cell) through capacitors. Again, in each symmetrical bisection, K number of NRNs are series cascaded through LC π-circuits. This results in a Kth order N-band stopband (notch) response in differential mode (DM) operation whereas provides a passband response when excited by a common mode (CM) signal. Reconfiguration of any DM stopband is obtained by using tunable capacitors for the corresponding LC π-circuit in each N-band cell and also, for its coupling capacitors to the NRNs. To validate the proposed topology, a dualband differential tunable BSF is designed and fabricated where both DM stopbands are controlled independently in the range of 1.16 GHz-1.32 GHz. Also, the bandwidth of each band is varied independently by 20-50 MHz without affecting the other band. At any tuning state, DM stopband rejection for each band is found to be ≥ 19 dB, resulting in a minimum CMRR value of 19 dB. The fabricated prototype occupies an area of 0.13λ g × 0.04λ g (21 mm × 7 mm) where λ g is the guided wavelength at the center frequency of the entire spectral range, and the experimental results show a good agreement with the simulation results.

“…Currently, piles of wideband dual-polarized antennas have been proposed in [2][3][4][5][6][7][8][9][10][11][12][13]. Cross dipole antennas in [2][3][4][5] and patch antennas in [6][7][8] are two classic wideband antenna types. In the design of [9], a dual-polarized antenna with wide operating band, high port isolation and good radiation performances is proposed by loading some dipoles.…”

In this paper, a wideband ±45 • dual-polarized antenna is proposed for the wireless communication. An annular ring patch with four arc-shaped slots is employed to generate a wide operating impedance bandwidth. By introducing four open stubs to the antenna element, the impedance bandwidth is enhanced. The antenna has a broad impedance bandwidth (VSWR < 2) of 51.2% (1.63-2.75 GHz) and a high port-to-port isolation of 27 dB over the entire band of operation. In addition, a 1 × 4 antenna array is developed for the wireless communication. Experimental results illustrate that the antenna array features wide operational bandwidth, high port isolation and superior radiation performance.

“…This problem can be solved by using a differential design with high Common-Mode Rejection Ratio. For improved performance, existing literature introduces complex structures, like stacked designs or stub designs, making them impractical for consumer type applications [13,14]. Moreover, even though dipoles are differential in nature, differential characteristics are not well studied, and most of the configurations are single ended with a built in balun for single ended characterization.…”

In this letter, a tuning fork shaped, differential dipole antenna, with two floating reflectors, is presented. The dipole antenna resonates at 1.22 GHz and has a fractional bandwidth (FBW) of 16.39% and a differential impedance of 100 Ω. The proposed antenna is composed of quarter wavelength tuning fork shaped dipole arms in the top layer. To improve robustness, while connecting to the differential circuits, two floating reflectors are used on the bottom layer, beneath the dipole arm. This method helps improving the gain by 7%. A microstrip-to-coplanar strip line (CPS) transition is designed to measure the stand-alone differential antenna. The measured gain and efficiency of the antenna are 2.14 dBi and 84%, respectively, at the resonant frequency. The possible targeted applications are circuits with differential inputs/outputs, like energy harvesting circuits, radio frequency tags, wireless communications and any other wireless sensor network nodes. Details of the design along with simulated and experimental results are presented and discussed.
