“…Some performance comparison between the present antenna and other reported antennas in the similar topic is given in Table II. Compared with the antenna reported in [10,[13][14][15][16][17][18][19][20][21][22][23][24], which are not easy to be extended to an array antenna, the presented antenna achieves the highest aperture efficiency. When the antenna works at 2.53 GHz, the gain is higher than 9.5 dBic, and the aperture efficiency is 70%.…”

“…The helix antenna [6] and spiral antenna [7] are well-known examples of broadband CP antennas. Apart from the antennas mentioned above, CP antennas can also be achieved by using a polarizer to convert the LP wave to CP wave [8][9][10]. One main advantage of utilizing a polarizer is that it can enhance the gain of CP antenna without resorting to an array antenna which requires a complicated feed network.…”

“…In [8], using meander lines to design a polarizer consisting of four substrate layers was reported. In [9] and [10], metasurfaces were used to convert LP wave to CP wave. Compared to the conventional CP antenna array, using a polarizer to generate CP waves does not need a complex, lossy feed network.…”

“…Although one polarization reconfigurable antenna with a polarizer was reported in [10], it was obtained by mechanically rotating the polarizer, which has the disadvantage of slow switching. Besides these advantages mentioned above, it will also be demonstrated in this paper that the proposed polarization reconfigurable CP antenna using EPRP can be easily extended to a large-scale array antenna if higher gain is needed with minor modifications to the feed networks and bias circuits.…”

Abstract-A novel polarization reconfigurable planar lowprofile antenna is presented. The antenna consists of an electronically reconfigurable polarizer and a slot antenna. The polarizer is loaded by PIN diodes and by changing the states of the PIN diodes, the linearly polarized (LP) wave generated by the slot antenna can be converted to either right-hand circularly polarized (RHCP) or left-hand circularly polarized (LHCP) wave. The polarizer contains 16 unit cells, which are arranged as a 4×4 array. Each of the unit cells has two layers and is printed on two sides of the substrate. The presented antenna radiates RHCP waves when the PIN diodes of top side are ON while it radiates LHCP waves when the PIN diodes of bottom side are ON. An analysis of the antenna is provided by using equivalent circuits. To verify the design concept, one prototype at 2.5 GHz band is designed and fabricated. Good agreement between the measurement and simulation results is obtained. The measured results show that the antenna achieves a gain better than 8.5 dBic in both RHCP and LHCP with 70% aperture efficiency. It is also shown that the presented design can be easily extended to the design of large-scale arrays without increasing the complexity of the DC bias circuit. The advantages of the proposed design are simple planar structure, low profile, flexibility in designs, high isolation between DC bias circuit and RF signals, high power handling, high gain and low cost. The proposed design can also be applied to the design of antennas at other frequency bands.
