“…16 Several antennas employing diverse reconfigurability methods have been documented in literature. [17][18][19][20][21][22][23][24][25][26][27] The objective of this paper is to design a frequency reconfigurable microstrip patch antenna having two linked slots in radiating element and a microstrip feed line printed on the back side. The antenna is reconfigured using a lumped element switch, placed on a microstrip feed line on the back side in the simulation.…”

In this paper, a reconfigurable microstrip patch antenna with two linked slots and a microstrip feed line is reported, which is useful for Bluetooth/WLAN/ISM (2400-2484 MHz), high frequency LTE band ( 2496-2690 MHz), WiMAX (2.50-2.69 GHz), S-DMB (2605-2655 MHz) and X band (8.0-12.0 GHZ) applications. The antenna is reconfigured by adding a PIN diode as a switch in the feed line. The simulation of proposed antenna has been performed with CST Studio Suite 2022. The antenna resonates at 4.70 GHz and 9.765 GHz under ON condition and resonates at 2.64 GHz, 4.71 GHz, and 10.07 GHz under OFF condition. The antenna is fabricated and measured results are found in close agreement with simulated results.

“…The direction of the electric field vector is changed at the time of reconstruction. Frequency reconfigurable antennas are very useful owing to their tunable operating frequency, which can be classified into two types, band switching and continuous tuning, respectively [18][19][20][21]. The radiation pattern of an antenna can be classified into omnidirectional radiation, bidirectional radiation, unidirectional radiation and multidirectional radiation.…”

A broadband high gain polarization reconfigurable antenna based on metasurface has been presented. The antenna is composed of a planar metasurface, a slot antenna and an air cavity. The metasurface is made up of 64 identical patches, and all the patches are on the top surface of the substrate. The spatial equivalent circuit of the metasurface is discussed and two approximate calculation formulas of the equivalent circuit are obtained. The antenna can be reconfigured to linear polarization, left-hand and right-hand circular polarizations by adjusting the relative positions between the metasurface and the planar slot antenna. The gain of the antenna is improved. In order to verify these methods, the antenna is studied and designed to operate at around 11GHz. The simulated and measured results show that the 3dB axis ratio bandwidth is 10-12 GHz (fractional bandwidth 18.18%) and maximum gain of 14.6 dBi.
