“…For the past few years, many researchers have investigated this phenomenon for the purpose of overcoming it. Meanwhile, there are many techniques which possess different structures are capable of achieving broadband antennas, such as coplanar coupled feed [8], aperture coupled feed [9,10], Open square loop patch [11], slot-coupled patch [12], proximity fed square ring patch [13], E-shaped patch [14], coupled annular ring antenna [15], slotted rectangular patch [16], H-shaped antenna [17], meandering probe-fed patch [18], E-H shaped patch [19], Wshaped patch [20], U-shaped patch [21], and stack patch [22]. By using these techniques, a wider impedance bandwidth of up to 50 % has been achieved.…”

In this paper, a new compact suspended antenna is presented for ultrawideband (UWB) application. In the proposed design, a new unequal arm U-shaped feeding patch is suspended below an H-shaped radiating patch to produce wide bandwidth through the electromagnetical coupling technique. This new U-shaped feeding patch is connected to a probe to compensate for probe inductance. Two shorting strips are introduced to hold the radiating patch above the ground plane, as well as reduce the antenna's size. These strips improve the bandwidth at the lower operating band. The proposed antenna has a compact dimension of 0.129λ × 0.186λ × 0.096λ, where λ is the wavelength of the lowest operating frequency. The proposed antenna has been optimized and its parametric study is performed using an electromagnetic field simulator, based on the finite element method. The proposed antenna is prototyped and measured. Measured results indicated that the proposed antenna structure has achieved an impedance bandwidth of 103.86 %, ranging from 4.3 to 13.59 GHz at VSWR ≤ 2. The measured results of the wideband and stable radiation patterns with acceptable gain signify the effectiveness of the proposed antenna configuration in the context of UWB application.

“…But, unfortunately they have some limitations and disadvantageous such as relatively low efficiency and low power, spurious feed radiation, narrow frequency bandwidth and relatively high level of cross polarization radiation (Garg, 2001). To overcome these limitations and disadvantageous, researchers have been proposed and investigated many techniques such as slotted patch antennas, microstrip patch antennas on an electrically thick substrate, probe feed stack antenna and the use of various feeding and impedance matching techniques, the use of multiple resonators (Alam, Islam, & Misran, 2012;Azim, Islam, Mandeep, & Mobashsher, 2012;Chen & Yung, 2009;Habib Ullah & Islam, 2012;Islam, Mobashsher, & Misran, 2010;Samsuzzaman, Islam, & Mandeep, 2012;Samsuzzamana, Islamb, & Faruqueb, 2013;Shakib, Islam, & Misran, 2010;Tiang, Islam, Misran, & Mandeep, 2011). In this paper, an effort is performed to design a triangular fractal antenna of effective radiation, intact size and multiband properties.…”

In this article, electrically small, triple band, triple frequency X shaped patch antenna is presented. The proposed X shape patch antenna consists of five rectangular slots which produces dual band operation for Ku band applications and another one for K band applications. In order to achieve multiband operation from conventional rectangular slot, it is introduced three equilateral triangle slots in left, right and upper edge respectively, and two small triangular slots are protruding both sides of the feed line. By increasing the number of steps, the antenna's operating bandwidth, with return loss less than -10 dB, covers the frequency ranges from 15.104 GHz to 15.632 GHz, 17.336 to 17.912 GHz which is suitable for Ku band applications and 18.476 to 19.28 GHz which is suitable for K band applications. The proposed antenna has also achieved symmetric and almost steady radiation patterns and peak gains of 4.80 dBi, 6.42 dBi and 3.91dBi at these operating bands.
