“…This PRPA design is able to reconfigure the beam maximum at −45 • , +45 • , ±50 • , and 0 • in the H-plane. To the best of the authors' knowledge, no existing work based on a parasitic array structure similar to the proposed antenna [17,21,22] has reported beam reconfiguration at four distinct directions which covers from 45 • to −45 • in the H-plane, as achieved in this report.…”

“…However, a total of twelve switches are used in the design, and measurement is carried out using metallic strip as an ideal switch instead of practical RF switch. An antenna with reconfigurable radiation maximum consists of a central driven patch, and two vertically placed parasitic patches are proposed in [17] for Ka-band satellite applications. Switching of MEMS switches between the driven and parasitic patches results in reconfigurable major lobe orientation in the H-plane at +17 • , −25.8 • , +3.5 • , and +0.7 • .…”

A pattern reconfigurable microstrip patch antenna with two parallel parasitic patches placed close to both sides of a rectangular driven patch is investigated and presented in this article. Four switchable shorting posts are used to enable the parasitic elements to act either as a reflector or director for beam reconfiguration, based on the operating state of four associated PIN diode switches. To avoid large change in the dimension of both parasitic patch and ground plane, and minimize its effect on beam steerability and return loss, two PIN diodes are placed on the top face and the other two on the slots etched on the ground plane. Radiation pattern of the proposed antenna can be reconfigured into four distinct directions in the H-plane with radiation maximum at +40 • , 0 • , −40 • , and ±45 • . With overall compact dimension of (35 × 55) mm 2 and acceptable return loss for all reconfigurable modes around 6.2 GHz frequency, the proposed antenna is a potential candidate for Wi-Fi 6E application. The measured peak gain varies between 3.9 dBi and 5.2 dBi with an average of 4.6 dBi for all beam tilt angles. Consistency between the simulated and experimental results validates the design theory and its promising application.

“…The reconfigurable parameters are: frequency, polarization, radiation pattern [3]. This agility can be achieved with changing antenna's configuration (electrical or physical) [4]. The reconfigurability of the dual-band antenna frequency is recently accounted with using one of the next diodes (PIN or Varactor diode) they can also helping us to obtain land different resonance frequencies maintaining the same radiation pattern.…”

The main aim of this work is to design a reconfigurable frequency antenna for the sake of evaluating its performances for telecommunication applications in the Ku and k bands. Using the HFSS software, the proposed antenna structure is optimized with etching two rectangular slots having the same size at the radiant element level. The partial ground plane length is limited at the Lg = 2 mm value. To achieve the desired frequency agility, a PIN diode is inserted into the microstrip line feeding the antenna structure. Depending on the states (ON/OFF) of the integrated PIN diode, several operating frequency bands are obtained. When the PIN is in the OFF state, the antenna covers two frequency bands ] GHz. However, in the ON state, the antenna operates in the [15.2 -15.6] GHz band. These results show that the suggested antenna in this work is a powerful candidate for ensuring the frequency reconfigurability in the frequency domain [14.7 -26.7] GHz.

“…We have done some research in reconfigurable antennas [ 10 , 11 ] and have fabricated several kinds of reconfigurable antennas in the same batch. Those antennas all have different structure configuration and size, and two of them can be found in references [ 10 , 11 ]. However, [ 10 ] only presents the structure configuration and measurement results, and [ 11 ] is only a simulation.…”

This paper proposes a radiating pattern reconfigurable antenna by employing RF Micro-electromechanical Systems (RF MEMS) switches. The antenna has a low profile and small size of 4 mm × 5 mm × 0.4 mm, and mainly consists of one main patch, two assistant patches, and two RF MEMS switches. By changing the RF MEMS switches operating modes, the proposed antenna can switch among three radiating patterns (with main lobe directions of approximately −17.0 • , 0 • and +17.0 • ) at 35 GHz. The far-field vector addition model is applied to analyse the pattern. Comparing the measured results with analytical and simulated results, good agreements are obtained.
