A varactor diode reconfigurable ultra‐wideband antenna that with electrically controlling the rejects on‐demand WiMAX, WLAN, and C‐BAND signals in the entire 3.1–10.3 GHz range is presented. The antenna design, embedding the active devices, integration with the varactor diode, and biasing network are described. A method to vary the rejection on‐demanded bandwidth is also provided. The fabrication prototype is conformal and double‐sided. Results indicate a successful integration and minimal interference of the varactor diode voltage and biasing circuitry with the antenna, paving the road for more integrated reconfigurable antenna on communication systems using active devices technology. © 2015 Wiley Periodicals, Inc.

“…Various printed monopole antennas with a single or dual band-notch function have recently been proposed [1][2][3][4][5]. Adopting an electrical and mechanical method as well as active elements may provide reconfigurable antennas in terms of frequency band [6], polarization [7], pattern [8] and multiapplication [9] in some UWB antennas. These elements are used to obtain alterable notched-bands.…”

In this letter, a novel frequency-reconfigurable monopole antenna with several switchable states including an ultra-wideband (UWB) state, filtering narrowband states, and a tunable filtering band state is presented. The antenna, which supports most applicable overlook narrowband frequencies between the 2-6 GHz, can be used in multiradio wireless systems. Moreover, the proposed antenna, which can avoid UWB interference and has narrowband functionality, has good potential for use in cognitive radio.

“…The vertical and horizontal linear polarizations were obtained by changing the bias state of the two p-i-n diodes. Circular polarization diversity were realized in [14,15]. In [14], by changing the bias states of the two PIN-diode embedded in the inverted-L-shape ground strips at the upper corner of square slots, RHCP and LHCP characteristics can be fulfilled.…”

“…Circular polarization diversity were realized in [14,15]. In [14], by changing the bias states of the two PIN-diode embedded in the inverted-L-shape ground strips at the upper corner of square slots, RHCP and LHCP characteristics can be fulfilled. By inserting meander-line strip in the radiating stub and two L-shaped slots in the ground plane, a multi-band frequency performance and dual circular polarization characteristic can be realized [15].…”

“…By electrically controlling the p-i-n diodes connected to the Y-shaped and T-shaped feeding line respectively, polarization reconfigurable antennas were obtained. CPW-fed planar antennas were widely used in reconfigurable antenna designs due to their simple structure [13][14][15]. In [13], a polarization reconfigurable CPW-fed slot antenna was proposed.…”

Abstract-In this paper, a CPW-fed reconfigurable clover-shaped antenna with switchable circular polarization is proposed. This antenna consists of a clover-shaped patch, four p-i-n diodes, and two pairs of quarter-circular-rings. By electrically controlling the four p-i-n diodes to form two orthogonal bow-tie shaped current paths, the proposed antenna can be operated in two modes: the left-hand circular polarization (LHCP) and right-hand circular polarization (RHCP) modes. Two pairs of quarter rings are used to improve the bandwidth and AR performance of the antenna. The measured 10-dB reflection coefficient and 3-dB axial-ratio (AR) bandwidth of the prototype antenna is approximately 12.3% and 19%, respectively, which is enough for some wireless applications such as WLAN IEEE 802.11 b/g (4%). Gain and radiation pattern are also presented.
