“…Compared with Ref. 34, it is reduced to 38%. The arms on the double-side of the substrate are soldered onto the printed meander feeding line by 8 p-i-n diodes (SMP1340-079LF from Skyworks), that is, S 1 -S 8 , as shown in Figure 2.…”

“…Compared with Ref. 34, this reservation design is more meaningful. The voltage source (3 V) is loaded between the dc pad and the bottom patch (V g ), that is, one pole of a 3 V battery is welded to the dc pad, and the other pole is connected to the coaxial line outer conductor by a dc isolation module.…”

“…In Ref. 34, the aperture for generating magnetic current adopts the improved form of slot in Ref. 33, that is, the cavity is improved into a half‐mode cavity substrate integrated waveguide with three shorted and one side opened, and the electric field generated on the open side of the waveguide obeys cosine distribution rather than uniform distribution.…”

A reconfigurable, planar, and end-fire circularly polarized (CP) antenna with wide beamwidth is presented, which exhibits the bidirectional radiation with the same sense by combining two pairs of identical CP elements placed in a back-to-back configuration. The design of the element includes a meandering phase delay line, which connects a printed electric dipole and a quarter-wavelength shorted microstrip patch. Then, eight p-in diodes are employed in the two dipoles arms to realize either left-handed CP (LHCP) or right-handed CP (RHCP) by manipulating the DC bias voltage across p-in. The prototype is designed to operate at a center frequency of 5.8 GHz with a size of 0.61 × 0.50 × 0.029 (λ 0 3), where λ 0 is the wavelength of the center frequency. Also, its end-fire beam is in parallel with its plane. Experimental results show that the overlapped bandwidth for 10-dB return loss and the 3-dB axial ratio (AR) of the bidirectional end-fire antenna is from 5.72 to 5.89 GHz for the two CP states. The half-power beamwidth (HPBW) in the horizontal and vertical plane are 95 /115 at the 5.8 GHz.

A bidirectional dielectric resonator (DR) antenna array using back-to-back quasi-Yagi antenna configuration is proposed and implemented for the first time. The DR operating at higher-order TE3δ1 mode is used as a magnetic dipole, applying for the driver of quasi-Yagi antenna. Due to the high-order mode employment, the antenna gain can be enhanced. By partially loading the metallic strip on the side wall of the DR, the gain can be further enhanced. In addition, a simple dual Marchand balun is constructed for feeding the two quasi-Yagi antennas directly for bidirectional radiation. To verify the design concept, a prototype operating at the X-band is fabricated and measured. Good agreement between the simulated and measured results can be observed.

As an alternative to conventional wireless communication techniques that use amplitude, frequency, and phase modulations, polarization modulation (PoM) provides an additional degree of freedom for the modulation of carrier waves and allows the realization of simple transceiver designs. PoM also enhances physical‐layer security in wireless communication systems owing to its vector‐attribute and direction‐dependence features. In this study, a prototype of PoM wireless communications based on a digital coding metasurface that can dynamically control the polarization of electromagnetic waves in a certain frequency band is demonstrated. The binary digital signals can be encoded on the optical rotation states of the circularly polarized beams through the real‐time control of the bias voltages applied on the metasurface and successfully decoded at the receiving end. Because the metasurface is separated from the emitting antenna, the design can simplify the setup for multichannel communications and provide more flexibility by setting the emitting antennas at different operating frequencies at any time.
