“…However, the more controllable reconfigurable patterns still involves problems and needs more effort. Such as literature, 5,6 the proposed antennas could not achieve a 360degree scanning in a particular plane. And among, 7-10 these types of pattern reconfigurable antennas could only steer its' radiation patterns in azimuth plane by a fixed spacing of steering angle and are incapable of adjusting their main beam directions within a small range.…”

A new pattern‐reconfigurable antenna with the function of 360° wide‐beam scanning and main beam direction finely‐adjustable is proposed in this letter. The antenna consists of a central feeding disc which surrounded by four snowflake radiators on the top layer of the FR4 substrate. PIN diodes are placed between the disc and each snowflake patch for realizing the wide‐angle beam steering of the antenna. By controlling the four PIN diodes on the top layer, main beam can be switched in four directions with about 90° steps in the H‐plane (17°, 106°, 197°, and 287°).The bottom layer of the substrate includes a ground plane with eight rectangular ring slots. Eight PIN diodes installed on each slot are used to further control the beam direction of the antenna. By controlling the states of the PIN diodes on the bottom layer, the main beam of the proposed antenna is capable to deflect rightward or leftward about 10° on the basis of the original four states. The simulated and measured results show that the antenna operates well at 3.64–3.88 GHz under 12 states and achieves good performance with flexible pattern reconfigurability in 12 directions. The proposed antenna could be applied in 5G wireless communication systems.

“…And in Ref. [5], the proposed antenna can realize small-angle beam steering in both E-plane and H-plane by introducing CSRR (Complementary Split-Ring Resonators) structure on the ground. However, the more controllable reconfigurable patterns still involves problems and needs more effort.…”

“…In addition to improved performance, multi-frequency operation in a single antenna reduces space and cost. Pattern reconfigurable antennas are attractive in applications such as surveillance and tracking because they produce more than one radiation pattern with different directivity at the same operating frequency [9,10]. In addition, manipulation of patterns is useful in avoiding noise sources, mitigating electronic jamming, improving security and increasing energy efficiency.…”

Due to the fast development of wireless communication technology, reconfigurable antennas with multimode and cognitive radio operation in modern wireless applications with a high-data rate have drawn very close attention from researchers. Reconfigurable antennas can provide various functions in operating frequency, beam pattern, polarization, etc. The dynamic tuning can be achieved by manipulating a certain switching mechanism through controlling electronic, mechanical, physical or optical switches. Among them, electronic switches are the most popular in constituting reconfigurable antennas due to their efficiency, reliability and ease of integrating with microwave circuitry. In this paper, we review different implementation techniques for reconfigurable antennas. Different types of effective implementation techniques have been investigated to be used in various wireless communication systems such as satellite, multiple-input multiple-output (MIMO), mobile terminals and cognitive radio communications. Characteristics and fundamental properties of the reconfigurable antennas are investigated. writing-review and editing, N.O.P. and R.A.A.-A.; investigation, N.O.P., H.J.B., Y.I.A.A.-Y. and A.M.A.; resources, N.O.P. and R.A.A.-A.; for other cases, all authors have participated.

“…The beam scanning ability can be employed to either save energy by directing the signal toward intended users or provide larger coverage. A few novel designs have been developed that can scan the beam ±α • with respect to the boresight direction (α is usually less than 50) [9]- [11].…”

Pattern-reconfigurable antennas with multiple switchable beams, especially with both boresight and endfire directions, are highly desired for wireless communications. In this letter, a novel pattern-reconfigurable antenna is proposed that provides an efficient solution. By reconfiguring parasitic striplines placed around a radiating dipole and reflecting metal pieces under the dipole using p-in diodes, the antenna main beam can be switched to five directions in the elevation plane, approximately from −90 • (left endfire), −45 • , 0 • (boresight), +45 • , to +90 • (right endfire). The developed antenna operates at 2.45 GHz with dimensions of about 0.57λ×0.45λ×0.28λ. An antenna prototype was fabricated and measured. For all five directional beams, The measured |S11| values are below −13dB, and the measured realized gains range from 5.2 to 6.5 dBi. They agree reasonably well with the simulated ones.
