A coplanar waveguide fed polarization reconfigurable monopole antenna is proposed in this letter. The proposed antenna consists of L‐shaped stubs placed on either side of a monopole, two p‐i‐n diodes and a slot in the ground plane. In the proposed antenna structure, the switching element is not directly connected to the feed line. Depending on the switching state of the p‐i‐n diodes, the antenna either radiates left/right circular polarization or linear polarization. To validate the proposed design, the antenna was fabricated and its performance was measured. Since the ground plane is electrically small, the effect of the cable and SMA connector on the performance of the antenna is also investigated. The measured impedance bandwidth is 66.78% (3.67 GHz to 7.35 GHz) and the axial ratio bandwidth is 13.62% (4.24‐4.86 GHz) for circular polarization and 23.61% (3.81‐4.83 GHz) impedance bandwidth for linear polarization.

“…The key advantage of RAs is its ability to satisfy the need for multifunctional operation, and then reduces the size and the cost of radio system. A great many studies have been contributed to RAs, but most are based on the electric reconfiguration, such as dual band varactor‐loaded slot patch antenna , compact reconfigurable dielectric resonator antenna , and the others . The electric reconfiguration needs extra complex circuits to supply electric power, which may connect with reconfigurable elements and then affect the performance of the RA.…”

We propose and experimentally demonstrate a frequency reconfigurable antenna using ferrite loaded half‐mode substrate integrated waveguide (SIW). The antenna design is based on a SIW cavity with an embedded ferrite slab, which causes the resonant frequency of the cavity tunable under bias magnetic field. The antenna features omni‐direction radiation and small size. A prototype antenna is designed and fabricated. The measurements show the tunable frequency bandwidth is over 11% covering frequencies 5.04–5.62 GHz in low bias magnetic field region, and 5% covering 4.28–4.5 GHz in high bias magnetic field region. The measurement is in good agreement with simulations. The gain of antenna is all over 1.6 dBi, and the frequency reconfiguration does not affect the radiation pattern of the antenna, providing a preferable feature for frequency reconfigurable antenna. This type of antenna may be a good candidate for practical applications such as base stations and satellites. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1365–1371, 2017

“…By adjusting the states of two diodes, the operating mode of the antenna can be electrically switched. Using some special feed structures can also achieve circular polarization [11,12]. By electrically controlling the p-i-n diodes connected to the Y-shaped and T-shaped feeding line respectively, polarization reconfigurable antennas were obtained.…”

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.
