“…In [7], a frequency-pattern reconfigurable antenna was designed, and the reconfiguration process was achieved using an electrical switching mechanism with four PIN diodes. The antenna operates at 2.45 GHz, 3.1 GHz, 4.1 GHz, 3.8 GHz, 7.8 GHz, and 9.5 GHz, which is suitable for various wireless applications.…”

“…From the above research [7][8][9][10], the antenna suffers from low to moderate gain arising from the capacitive effect of the ground plane in addition to using via [9] that produces losses and affects the radiation pattern. To eliminate the losses resulting from such a technology, it has become necessary to present new designs that reduce these losses; This is the focus of this research.…”

The subject matter of the article is the analysis and design of a via free metamaterial antenna based on a composite right/left-handed transmission line (CRLH-TL) structure. The goal is to design a high-gain antenna with dual-band resonance capable of changing its resonance frequency and gain adaptively. The tasks to be solved are creating an antenna with a high gain-bandwidth product along the operated band, achieving adaptive frequency reconfiguration and creating a direct antenna modulation process using active elements. The simulation methods used are: the proposed antenna is designed by integrating a CRLH-TL structure to a 1D array based on two types of unit cells: The first unit cell is realized from a Hilbert curve of the 3rd order, and the second one is based on the 1st order of Minkowski – stepped impedance resonator (SIR). The antenna parts are printed on a Taconic RF-43 substrate with thickness = 1.57 mm. The following results were obtained: The Hilbert/Minkowski–SIR antenna achieved dual-band operation with a maximum gain equal to 14 dBi and 18 dBi at 5 GHz and 5.5 GHz, respectively. Furthermore, by changing the states of the PIN diode, an amplitude shift keying direct antenna modulation process is achieved; for instance, at 5 GHz, the antenna can change its gain directly in the range from (12-14) dBi with good impedance matching. Finally, the proposed antenna shows a low profile and operates at different frequency bands within sub-6 GHz applications. Conclusions. The simulation results indicate that such antenna performance enhancement is the result of eliminating via conduction losses, ground plane capacitance losses and suppressing surface wave reflections due to the Hilbert/Minkowski SIR introduction.

“…Their frequency switching relied on a single varactor diode, and the effect of altering the diode's positioning was tested. An antenna using two PIN diodes is presented in [10], covering several frequencies from 3.1 to 9.5 GHz, while changing the radiation pattern for different operation modes. A multiband frequency reconfigurable antenna was designed and implemented in [11].…”

“…Most of the available literature concerning antenna reconfiguration characteristics via PIN diodes has so far concentrated on two or more PIN diodes [10][11][12]15,18,[21][22][23][24][25][26]. On the other hand, fewer studies have been published with only one PIN diode [14,27,28].…”

This paper presents a compact multifrequency reconfigurable patch antenna in terms of design and fabrication for operating in the S and C bands of the RF spectrum, which are overwhelmed by wireless applications. Reconfiguration is achieved by using a single PIN diode on the ground plane. By varying the voltage applied to the diode, three modes can emerge, exhibiting main resonant frequencies at 2.07, 4.63, and 6.22 GHz. Resonance switching requires a voltage of less than 0.9 V. The antenna fabricated on an FR-4 substrate, with a volume of 70 × 60 × 1.5 mm3, has a radiating patch element of a rectangular ring shape. The proposed low-cost antenna is easily implemented in a typical university lab-based environment. The total bandwidth for the three modes is close to 1 GHz, while the voltage standing wave ratio (VSWR) of the fabricated version of the antenna does not exceed 1.02, and the return loss is well below −40 dB for the three primary resonant frequencies.

“…The antenna has achieved dual-band operation in each switching state. The reconfigurable antenna can be designed with radiation pattern reconfigurability, i.e., the radiated power distribution can be controlled spatially in the antenna's surrounding area [19][20][21] . In 19 , a reconfigurable radiation pattern MIMO antenna is designed as a rectangular monopole with two parasitic strips equipped with PIN diodes.…”

This paper proposes a flexible, frequency-reconfigurable monopole antenna design with frequency selective surface (FSS) for Internet of Things (IoT) applications. The proposed antenna operates at three of the IoT frequency bands. This antenna is a coplanar waveguide (CPW)-fed monopole with two balanced arms printed on a thin ROGERS 3003 flexible substrate. The length of the right-hand arm of the antenna is used to achieve frequency reconfiguration by using PIN diodes. Three frequency modes of operation have been obtained; the 2.4 GHz frequency band with the right-hand arm is fully truncated, the 3.5 GHz frequency band with the two arms is completely maintained, and the 4 GHz frequency band with the right-hand arm is partially truncated. To improve the gain of the antenna, a simple FSS surface is designed to be placed under the antenna at a distance of 15 mm. The FSS operates efficiently from 2 to 4.5 GHz and has improved the gain of the antenna. A maximum gain of 6.5 dBi, 7.52 dBi, and 7.91 dBi has been achieved at the three frequency bands respectively. The behavior of the flexible antenna has been evaluated in both the flat and bent states, and stable performance has been observed in both cases.
