“…For multi-fed CP antennas, compared to the single-fed type, wide impedance and AR bandwidth can be easily achieved by designing a wideband feeding network with equal amplitude and ±90 • phase differences between the adjacent output ports. For instance, wideband CP antennas were realized by feeding annular-ring patch [11], bowtie dipoles [12], hybrid DRA and patch [13], stacked patches [14], quadrifllar helical antenna [15], or strips coupled annulus patch [16] using a wideband feeding network. Although the CP antennas mentioned above can achieve maximum impedance and AR bandwidth over 90%, these antennas are not polarization reconfigurable.…”

This paper presents a polarization reconfigurable differential circularly polarized (PRDCP) antenna with wide impedance and axial ratio (AR) bandwidth for right-hand circular polarization (RHCP) or left-hand circular polarization (LHCP). The antenna is composed of a bandwidth-improved radiator and a reconfigurable differential-to-single-ended sequential feeding network. The radiator consists of three patches, and four feeding lines to achieve the wide AR bandwidth and stable radiation patterns. The feeding network consists of two stepped coupled line couplers (SCLCs), and two switches that provide switchable quadrature excitations. By digitally controlling the inputs of the switches, the LHCP or RHCP mode can be selected. To verify the feasibility of the PRDCP antenna, a prototype is designed, fabricated, and measured. The measured results show that the bandwidths in the LHCP (RHCP) are 75.6% (81.8%) of a 10-dB matching, 66.7% (71.2%) of a 3-dB AR with stable radiation patterns of 7.4 dBi (7.4 dBi) peak gain.

In this article, a simple method for designing feed networks for wide-beam multi-fed helical antennas, suitable for satellite communications, is studied. Power division with similar phase differences for these antennas is obtained using serial feed network. The number of antenna arms is arbitrary, since the serial feed can be designed for any feasible number of outputs. Triple-fed helical antenna is studied in this article, as an example. The proposed S band triple-fed antenna benefits from 3 dB AR bandwidth of 24%. It has also low-level reflection coefficients throughout the bandwidth.

By employing 2 pairs of transmission lines, the difference between the even-/odd-mode impedance of the utilized coupled line can be controlled; hence the performance of the bandwidth and out-of-band rejection can be changed simultaneously. Detailed design equations are derived and can be easily applied in future works. Due to the inherent bandpass characteristic of the
