“…Accordingly, the multiband antenna is desired in many systems. In the literature reviews, there are various multiband antennas that have been developed over the years, which can be utilized to achieve the objectives of multiband operation, for instance, the PIFA [1,2] for using in mobile phone application, the slot spiral antenna [3] for dual band or multiband operation, the triangle-shaped monopole antenna [4], and other [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23]. Recently, the developing multiband antennas have been improved due to use of the fractal concept.…”

Abstract-This paper presents a multiband slot antenna with modifying fractal geometry fed by coplanar waveguide (CPW) transmission line.The presented antenna has been designed by modifying an inner fractal patch of the antenna to operate at multiple resonant frequencies, which effectively supports the digital communication system (DCS 1.71-1.88 GHz), worldwide interoperability for microwave access (WiMAX 3.30-3.80 GHz), IMT advanced system or forth generation mobile communication system (3.40-4.2 GHz), and wireless local area network (WLAN 5.15-5.35 GHz). Manifestly, it has been found that the radiation patterns of the presented antenna are still similarly to the bidirectional radiation pattern at all operating frequencies. The properties of the antennas, for instance, return losses, radiation patterns and gain are determined via numerical simulation and measurement.Corresponding author: C.

“…First, the dimension of the rectangular patch basically corresponds to the quarter wavelength of the associated resonant frequency [18,19]. In addition, the parameter results in not only the resonant frequency shifting but also the return loss level between the first and second resonant frequencies.…”

This paper presents a bandwidth enhancing technique using a modified ground plane with diagonal edges, L-shaped slot and parasitic patches with main patch for the design of compact antennas. The proposed low-cost, compact-size rectangular patch antenna on 4.7 cm × 3.6 cm printed circuit board (FR-4) is designed and validated through simulations and experiments. Results show that the ground plane with Lshaped slot in presence of the diagonal cuts at the top corners and the rectangular parasitic patches can increase the bandwidth. Return losses of −23.6 dB and −29.7 dB for the first and second resonant frequencies, respectively, can be achieved when the depth of the diagonal cut is 3 mm, the dimension of each rectangular parasitic patch is 10 mm×3.5 mm, and the L-shaped slot size is 7.5 mm ×2.5mm, providing a 41.27% wider bandwidth than Federal Communication Commission's(FCC) standard.

“…However, the main limitation of the conventional microstrip patch antennas is narrow bandwidth that restricts its operation where wider bandwidth is required. To overcome their inherent limitation of narrow bandwidth, many techniques have been proposed and investigated such as by using lower value of dielectric substrate, increasing the thickness of substrate [1], utilizing an impedance matching networks and different types of feeding techniques [2][3][4][5], use of stacked and coplanar structures [6], loading of slot and notch [7,8]. These techniques have some limitations except loading of slot and notch, because it enhances bandwidth without increasing the volume of the geometry.…”

Abstract-This paper presents a comparative study of rectangular base desktop shaped broadband patch antenna (Antenna1) and triangular base desktop shaped broadband patch antenna (Antenna2). Apart from base dimensions all parameters of both antennas are constant. The broadband characteristics are achieved by introducing two parasitic ground planes and notches are etched on the radiating patch. Both antennas are simulated, fabricated and tested for obtaining the desired performance. The designed Antenna1 shows bandwidth of 39.97% (4.95 GHz to 7.42 GHz) whereas an improved bandwidth of 49.0% (4.53 GHz to 7.47 GHz) is achieved through Antenna2. Further, gain and radiation pattern of the two antennas are compared and discussed. The effect of inclination angle 'α' on Antenna2 characteristics in obtaining the improved bandwidth is also studied. The proposed antennas are simulated, and results are verified experimentally.
