“…2 Therefore, such urgent needs always acquire relatively high cost with enough complexity antenna designs to work at the desired frequency specifications. 3 Mainly reconfigurable antennas based on active electronic devices to directly adjust the required frequency, radiation, and polarization independently tuned become one of the most urgent demands of modern technologies. 1 Reconfigurable antennas have several advantages over conventional antennas such as smaller size with high stability performance which reduces antenna system size and inter-symbol interference (ISI) impacts.…”

“…2 Thus, integration of the active electronic devices in a single antenna platform is one of the major challenges that current researches are potentially applied on. 3 For example, a portable-based direct antenna modulation was introduced in Pourghorban Saghati and Entesar 3 and Behdad and Sarabandi 4 for biomedical applications. A slotted patch antenna with two PIN diodes was presented in Aboufoul et al 5 for frequency and pattern reconfigurations in portable devices.…”

Design of a fractal printed circuit antenna structure for portable applications is presented in this paper. The proposed antenna consisted of a modified Hilbert patch printed on a flexible polyamide substrate. The antenna is surrounded with a defected electromagnetic bandgap (EBG) open loop. A parametric study based a numerical analysis is invoked to refine the proposed antenna performance. The proposed antenna is fabricated on polymer substrate with dimensions of 50 Â 60 Â 0.3 mm 3 . The proposed antenna performance is tested experimentally and compared to the simulated results from a commercial software package based on Computer Simulation Technology Microwave Studio (CST MW). The experimental results are found to agree well with simulated results. It is found that the proposed antenna design suites the applications of the frequency bands of UHF and ISM portable systems. The antenna shows two bandwidths from 0.8 to 1 GHz and from 2.3 to 2.6 GHz with average gain of around 3.1 and 7 dBi, respectively. The antenna performances are conducted based on analytical and numerical simulations.The fabricated prototype performances are measured experimentally to show excellent agreement with the simulated results. Finally, it is found that the proposed antenna frequency resonance and bandwidth are insignificantly affected when mounted in close to the human body; therefore, it would be excellent candidate to be in use with biomedical applications.

“…On the other hand, the substrate integrated waveguide cavity backed structures that can be fixed to almost any surface without disturbing its characteristics have been widely used on the design of frequency reconfigurable antennas [15][16][17][18]. In [15], a quarter-mode SIW cavity antenna employing the capacitive loading tuning method has been proposed.…”

The agile frequency antennas are widely used for wireless communication systems. This paper studies and designs a low-profile SIW antenna radiating from a circular slot graved in the ground plane, with the ability of alternating the frequency. The antenna is intentionally designed within a range of 1.8 GHz to 2.18 GHz obtained by varying the DC bias voltages from 0 to 26 V, which is able to cover the GSM1800, the LTE, and the UMTS wireless standards. The tuning technique consists in the integration of two varactor diodes across the circular slot. A prototype was manufactured, and the experiment results correspond well to those of the simulations.

“…Mostly, the conventional slot antennas are being used for multiband applications but the disadvantage of the conventional slot antennas is two-sided radiation pattern which makes them a weak choice for being used on an additional ground plane, such as the body of a vehicle, a printed circuit board (PCB), or any other scattering object. To eliminate the back side radiation, cavitybacked slot antennas with high-radiation performances appear to be more amenable [10,11]. By using SIW structures, the same radiation performance of conventional cavity-backed slot antennas can be achieved along with the advantages of low profile, ease of fabrication and compatibility with planar integration [12,13].…”

In this paper, a dual-band reconfigurable substrate-integrated waveguide (SIW) cavity-backed slot antenna 1 £ 8 linear array is presented with dual states. The proposed SIW antenna array combines the features of the conventional metalized cavity-backed patch arrays such as surface wave suppression, high efficiency with low-manufacturing cost. The basic element has been designed, fabricated and the performance has been verified in the outdoor antenna test range. Here, PIN diodes have been used as a switching device to achieve the reconfigurability with dual-band operation. A corporate feed network has been designed and integrated with the antenna to make it as a linear array.
