“…It is widely explored since it gives more benefit than the conventional antennas whereby using a single antenna is competent to operate or support multiple operating frequencies [1], radiation patterns [2] and polarization [3]. Moreover, RMA is convenient for a certain design because its manufacturing cost is very economical as the size is small and compact.…”

“…The basic working principle of this reconfigurable antenna is achieved by switching the status of an RF switch either to ON or OFF mode which then affects the current distribution of the antenna. Switching components such as PIN diodes [2], varactor diodes [4], MEMs switches [5], and optoelectronic switches [6] are normally used to achieve frequency-reconfigurable antenna. Yet, the PIN diode switch is an optimum choice because it has low insertion loss, fast response, low control voltage, and reliable.…”

Abstract-In this paper, a new Frequency-Reconfigurable Stacked Patch Microstrip Antenna (FRSPMA) with a new coupling method applied in an aperture-coupled technique controlled by the switching circuit is presented. This antenna uses a combination of aperturecoupled technique and stacked patch in order for the radiating elements to increase the bandwidth. Two shapes (I-shape and H-shape) and sizes of aperture slots are etched onto the ground with a purpose to couple the energy between feedline and stacked patch. One PIN diode switch is integrated in the feed network to control the length of the feedline. A variation of the feedline length controls the selected aperture slots to be active. The waves from the selected activated aperture slots will radiate to particular radiating patch (top or bottom patch) and achieve the frequency reconfigurability. When the switch is in ON mode, the antenna has a capability to configure its operating frequency at 2.6 GHz and at 3.5 GHz during the OFF mode. Besides that, the air gap is used to improve and avoid any coupling problem between the aperture slots and both of the two patches. Improper alignment between the aperture slots and patches will interfere waves radiating from aperture slots to the particular patch. In addition, the proposed antenna produces a high gain of more than 5 dB during ON or OFF modes, respectively. The simulated results are compared with measured results.
