“…The second one is to select and excite different working modes of a single antenna [7]- [9], and to make use of different current distributions of these modes for realization of pattern diversity. The last one is to reconfigure electrical structure of the antenna [10]- [11] so as to yield the different radiating apertures as expected. In particular, the latter two techniques have played an important role in PR antenna design nowadays due to their advantageous performances in terms of radiation pattern, cross polarization and size of antennas.…”

In this article, a high-gain square patch antenna with reconfigurable broadside and bidirectional beams under operation of TM20 and TM21 modes is proposed. Initially, two open slots are loaded to the edges in two opposite sides of the radiating patch so as to reshape the current distribution of TM21 mode, by which its four-beam radiation pattern is transformed into the desired broadside beam. With this arrangement, the resonant frequency of TM21 mode can additionally get reduced towards that of TM20 mode. By utilizing a simple feeding network with four p-i-n diode switchers, TM20 and TM21 modes can be further excited with common-mode and differential feeding schemes, respectively, thus bringing out switchable broadside and bidirectional patterns. The simulated and measured results are found in good agreement, both demonstrating that the antenna achieves an overlapping bandwidth of 7.3% in a range from 2.35 to 2.54 GHz, and the measured peak gains as high as 10.4 and 9.6 dBi for the broadside and bidirectional states, respectively.

“…The length of the parasitic elements with respect to the driven element can be controlled electronically by embedding switches with them [2][3][4][5][6][7][8][9][10] or loading them with complex impedances. [12][13][14] Apart from the quasi-Yagi concepts, pattern reconfigurability can also be achieved by suitable use of switches [17][18][19] with the driven antenna element to excite different modes in a common bandwidth.

In this study, novel designs of single‐band and tri‐band pattern reconfigurable antennas are proposed. The design of single‐band pattern reconfigurable antenna is accomplished by the use of varactor diodes with the parasitic elements placed on both sides of the driven conventional printed dipole antenna. By tuning the capacitance of varactor, the antenna operates in four different configurations of radiation pattern which include bi‐directional end‐fire, broadside, and uni‐directional end‐fire radiation patterns. The tri‐band pattern reconfigurable antenna design is achieved by the use of parasitic elements on both sides of a tri‐band driven dipole antenna. Dual‐band LC resonators are used as loading elements along the arms of printed dipole to get two lower order modes in addition to the reference dipole mode, resulting in a triband operation of the driven element. The electrical lengths of the parasitic elements with respect to the tri‐band driven element are controlled by suitably embedding varactor and PIN diodes with them. The proposed tri‐band antenna operates in ten different configurations of radiation patterns in the three operating bands. Fully functional prototypes of single‐band and tri‐band pattern reconfigurable antennas along with the DC bias networks have been fabricated to validate the results obtained in simulation.

“…Meanwhile, there is also a trend of miniaturization and low cost. A reconfigurable antenna can be designed to be reusable at characteristics such as frequency, radiation pattern and polarization without increase of antennas [1][2][3][4], and has been a promising solution to meet these conflicting requirements [5,6]. Meanwhile, wideband pattern reconfigurable antenna has attracted significant attention for its flexibility and large capacity.…”

A clubs-shaped wideband antenna with reconfigurable radiation pattern is proposed. This antenna is composed of two tapered slots of mirror symmetry, embedded with two PIN diodes and fed by a 50 Ω coplanar waveguide (CPW). By controlling states of PIN diodes, two tapered slots can be shut down or opened. Consequently, the proposed antenna works in three radiation modes: one monopole pattern with a simulation frequency band (3.93-5.55 GHz) and two end-fire patterns with an identical band (3.29-6.13 GHz). The antenna is fabricated and tested. Measured results show good agreement with the simulation, which denotes that it is suitable for wideband wireless communication systems.
