Truncated rhombic microstrip patch array antenna with frequency reconfigurability

This paper analyzes the stacked patch antenna. The anticipated antenna employments gap coupled procedure. The frequency can be adjusted by switching, which can underpins numerous frequency ranges between 2 GHz to 6 GHz with ideal return loss and fine execution. The proposed antenna improves the assembly of aperture-coupled multilayered stacked patch to extend the transmission capacity. This plan employments diverse structures of the gap openings, is engraved onto the ground plane couple with nourish line and stacked fix. The gap spaces are utilized to emanate the waves for the particular transmitting patches to realize the recurrence re-configurability. In ON state the radio wire is anticipating its working point at double frequencies as 3.2 GHz and 4.2 GHz. In OFF state the radio wire can reverberate at 5.3 GHz. These frequencies are well reasonable for higher recurrence applications like WLAN and Wi-MAX.

“…Thus, the unique 'zig-zag' slot is embedded at two different orientations in x-and y-axis so that the proposed antennas can operate at two different frequencies by using the same patch size. The main reason of having this configuration is that the designs can be implemented for future development of a frequency reconfigurable antenna in an array configuration whereby the size of the radiating patch is maintained regardless of its frequency [21]. The size of the patch at lower frequency can be reduced which normally requires bigger patch size.…”

“…Consequently, by configuring the switches at the feed network to ON or OFF mode, the number of the activated patches can be controlled thus frequency-reconfigurable antenna can be achieved. In [15], the authors use the aperture-coupled technique to achieve the frequency-reconfigurable antenna. In this design, when one of the two switches at the feed network is in ON mode, two of four patch elements are activated (either on the left hand side or on the right hand side).…”

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.
