In this paper, a compact frequency reconfigurable circular patch antenna with an arc-shaped slot loaded in the ground layer is proposed for multiband wireless communication applications. By controlling the ON/OFF states of the five PIN diodes mounted on the arc-shaped slot, the effective length of the arc-shaped slot and the effective length of antennas current are changed, and accordingly six ... A quad-polarization and frequency reconfigurable square ... Fig. 1 shows the geometry of proposed quad polarization and frequency reconfigurable antenna with detailed dimensions. It consists of a square patch of side a printed on RT Duroid substrate of ε r = 2.2 and thickness h = 3.2 mm. At the two RF ports an impedance transformer matches the 50 Ω feed line to the patch.Fig. 1(a) shows a square ring slot with outer dimensions l × w etched in the ...

At present, some frequency reconfigurable antennas have been discussed in earlier literatures -. It is found that the antenna can operate at multiband from 2 GHz to 4.4 GHz and the operating frequency can be shifted ... Frequency Reconfigurable Microstrip Patch Antenna for ...
The antenna resulted in an omnidirectional radiation pattern which is an essential requirement for the wireless applications. In our proposed design, the two Antennas are isolated with the help of an annular slot. Four PIN diodes were employed for connecting the inner antenna with the outer one by using RLC equivalent of PIN diodes.
