“…The user's hand will not affect the matching of the bands and also the radiation efficiency [31]. For these reasons, we should design the antenna to have the ground plane as less sensitive as possible so that the performance mainly depends on the structure alone and not the surrounding elements [19,22]. For our proposed antenna, results in Fig.…”

“…However, if the ground plane also acts as a radiating part, the effect of the user's hand is likely to degrade the antenna performance when the antenna is fitted inside the mobile phone. This causes several practical engineering problems [19] - [22]. In some designs, the location of the antenna on the substrate is also an important factor to be considered as it can enhance the bandwidth of the antenna by few more percentages [23].…”

Abstract-The design of a small ultra-thin Printed Inverted-F Antenna (PIFA) with independent control on the resonant frequency bands is proposed. The antenna consists of a slotted radiator supported by shorting walls and a small ground plane. The structure is designed and optimized to operate at 2.09, 3.74 and 5 GHz with achievable bandwidths of 11%, 8.84% and 10%, respectively. These three bands cover the existing wireless communication frequency bands from 1.5 -6.8 GHz. Each of the three bands can be controlled independently without affecting the other two bands. The 2.09 GHz band can be controlled to operate between 1.5 -2.09 GHz (33.33%), the 3.74 GHz band can be controlled over the range of 3.57 -4.18GHz (15.76%) and the 5 GHz band can be controlled to cover the band from 5.00 -6.80 GHz (30.50%). Results of intensive investigations using computer simulations and measurements show that the ground plane and the feed locations of the antenna have marginal effects on the performance of the antenna. The effects of the user's hand and mobile phone housing on the return loss, radiation patterns, gains and efficiency are characterized. The measured peak gains of the prototype antenna at 2.09, 3.74 and 5GHz are 2.05, 2.32 and 3.47 dBi, respectively. The measured radiation efficiencies for the corresponding three bands are 70.12, 60.29 and 66.24 % respectively.

“…And it also have one major limitation is their narrow bandwidth characteristic. Researchers have been engaged in remaining this limitation for the past 20 years and have been successful in achieving an impedance BW of up to 90 percentage and gain bandwidth up to 70 percentages [1][2][3][4][5][6][7][8][9][10]. Ihe input impedance of a patch antenna is found to varies with frequency, thus limiting the recurrence extend over which the feed line can be coordinated to its component.…”

This paper presents a band notched WLAN self complementary ultra wide band antenna for wireless applications. The proposed antenna encounters a return loss (RL) less than -10 dB for entire ultra wideband frequency range except band notched frequency. This paper proposes a hexagon shape patch, edge feeding, self complementary technique and defective ground structure. The antenna has an overall dimension of 28.3 mm × 40 mm × 2 mm, built on substrate FR4 with a relative dielectric permittivity 4.4. And framework is simulated finite element method with help of high frequency structured simulator HFSSv17.2. the proposed antenna achieves a impedance bandwidth of 8.6 GHz, band rejected WLAN frequency range 5.6-6.5 GHz with vswr is less than 2.

“…This is due to their major advantages such as low profile, ease of manufacture, low cost and light weight. As the printed antenna performance is well known to be dependent on the ground plane, this aspect has been actively researched [1][2][3][4][5][6][7][8]. Radiation from the ground plane is inevitable as the electric currents are distributed on both the radiator and on the ground plane.…”

“…Radiation from the ground plane is inevitable as the electric currents are distributed on both the radiator and on the ground plane. Chen, See and Qing reported in [1] that by cutting a notch from the radiator, it would be possible to reduce the ground-plane effect on the performance of a small printed UWB antenna. In another effort, a microstrip-fed printed rectangular monopole antenna has been examined by introducing asymmetrical feed-line and a windowed ground plane, with the intention to reduce the ground-plane-dependent effects [2].…”

Abstract-The effect of shaping the ground plane on the performance of a square loop coplanar waveguide (CPW)-fed printed antenna is reported in this paper. Experimental results are presented on the reflection coefficient and radiation pattern of the investigated antennas. Simulation results are presented on the current distribution, input impedance and gain. It is observed based on the results that shaping the ground plane significantly affects the reflection coefficients, input impedances and current distributions.
