“…Proximity-coupled [3]- [8], aperture-coupled [9], [10], edge-fed, coaxial-fed [11], and CPW-fed [12] methods are the typical ways for designing sequential-phase feeding networks with phases of 0 , 90 , 180 , and 270 at four ports. However, these proposed 2 2 patch arrays have at least two substrate layers, which are not suitable for monolithic integration.…”

This communication presents a wideband circularly polarized (CP) 2 2 patch array using a sequential-phase feeding network. By combining three operating modes, both axial ratio (AR) and impedance bandwidths are enhanced and wider than those of previous published sequential-fed single-layer patch arrays. These three CP operating modes are tuned and matched by optimizing the truncated corners of patch elements and the sequential-phase feeding network. A prototype of the proposed patch array is built to validate the design experimentally. The measured -dB impedance bandwidth is 1.03 GHz (5.20-6.23 GHz), and the measured 3-dB AR bandwidth is 0.7 GHz (5.25-5.95 GHz), or 12.7% corresponding to the center frequency of 5.5 GHz. The measured peak gain is about 12 dBic and the gain variation is less than 3 dB within the AR bandwidth.

“…Always, simple design and wide axial ratio (AR) bandwidth is attractive. Examples with at least two substrate layers with proximity coupled, aperture coupled, and CPW-fed technique have been proposed in [1][2][3][4][5][6][7][8][9][10]. Other single-layer examples with less complexity and CP bandwidth have been proposed in [11][12][13][14][15][16].…”

A 2×2 circularly polarised (CP) antenna array with four square radiating patch elements has been introduced here. The array elements are sequentially rotated and have been fed by a simple single‐layer feeding network with sequential phase structure. This feeding network generates successive phase difference at its four outputs. To have a wide CP bandwidth, the proposed method of feeding network has been combined with new simple tuning stubs which are embedded in radiating patch elements. The common reflection coefficient bandwidth (S11<−10thinmathspacedB) and axial ratio (AR) bandwidth (AR <3 dB) is 1000 MHz which covers 1.5–2.5 GHz frequency band and according to the centre frequency of 1.8 GHz, the frequency bandwidth is ∼55.5%. Furthermore, the peak gain of the proposed antenna array is ∼7.5 dBi at the frequency range of 1.7–2.3 GHz.

In this article, a 2 × 2 circular polarized (CP) antenna array, which is using sequential rotation (SR) technique in feeding network, has been introduced. The feeding network uses two 90° arcs and several rectangular lines with the same width. The length of these elements is multiple of λg/4 to produce 90° phase difference in 4 outputs of feeding network. By connecting the patch elements to the feeding network, which have been surrounded with radiating patch elements, design of 2 × 2 patch array has been completed. This array antenna with an incomplete ground which helps to have a better impedance matching, has been caused to reach a wider axial ratio (AR) and impedance bandwidth. The prototype of the proposed antenna array is built to validate the antenna performance. By using these techniques, a common bandwidth of 1.15 GHz has been achieved for impedance bandwidth (S11 < 10 dB) and AR bandwidth (AR < 3 dB) and 7.5 dBi maximum gain. In addition, the gain is more than 4 dBi in desired frequency range. According to the frequency range of 2.8‐3.95 GHz, the proposed antenna is suitable for S‐band applications.
