“…With the development of satellite navigation 1,2 and airborne/shipborne radar 3 technology, phased array antennas have been widely used in communication and radar systems for their flexible beamforming capability 4 . Compared with the passive beamforming network‐based antenna arrays, 5,6 phased arrays can achieve more controllable functions such as multibeam and two‐dimensional beam scanning by a single antenna array 7 …”

In this article, a pattern reconfigurable antenna is proposed for wide beam scanning phased array applications. Different from the wide beamwidth unit design, the large beam scanning range of the proposed antenna array is realized by the reconfigurable radiation patterns with the different tilted angles of the antenna unit. The tilted beams can enhance the total beam coverage range of the antenna unit with high directivity, thus increasing the beam scanning range of the antenna array. The tilted beams are realized by the combination of the concentric circular and annular patch antennas. A PIN diode-loaded reconfigurable feeding network is designed to feed the patches with reconfigurable phase differences. The feeding network can achieve a good impedance matching effect and guarantee the symmetry of the tilted beams. To verify the beam scanning performance of the proposed antenna, a 1 × 4 linear array is fabricated and measured. The results prove that the antenna can achieve ±61°beam scanning range with ±78°3 dB beam coverage range and the maximum sidelobe level (SLL) of −8.0 dB. The characteristics include lowprofile, high efficiency, low SLL, and wide beam scanning range making it a very attractive choice for phased array antenna applications.

“…One of the first applications can be found in [5], where Kraus adopted helices as radiating elements. More recently [6], the same approach was adopted, employing a 3-element sequentially rotated array as a single element in a larger array.…”

A Dual-Band Circularly Polarized Patch Array Antenna for Phase-Only Beam Shaping with Element Rotation

et al. 2021

In this paper, an innovative patch antenna optimally designed for phase-only beam shaping is presented. The radiating element generates a circularly polarized field and exhibits two separate operative frequency bands. The element is center-fed by a pin connected to the beam forming network (BFN) layer. This unique feature allows us to generate any given phase distribution by simply proportionally rotating the radiating elements with respect to their feeding points. An effective phase-only synthesis method is also illustrated, which takes into account the radiating element rotations. To demonstrate the effectiveness of the proposed solution, two linear arrays for global coverage have been designed, specifically operating in the E1 and E6 frequency bands of the European Global Navigation Satellite System (GNSS) Galileo. The two presented antennas performance have been verified with full-wave simulations, showing excellent agreement with theoretical results and, therefore, confirming the effectiveness of the presented design approach.
