“…In [10], an ACS fed meandered shape structured monopole antenna is proposed with wide impedance bandwidth. Dual-band antennas for various wireless applications are designed by using a hexagonal radiating patch [11], two stepped rectangular patches [12], a modified rectangular radiating patch [13], a hexagonal patch loaded with a strip [14], and all are excited by adopting CPWfed mechanism. From the above discussion, it is clear that the overall size of the antenna is minimized in the case of using the ACS fed technique.…”

In this work, a novel 4 element Multi-Input Multi-Output (MIMO) antenna is reported. The proposed antenna has a size of 50 × 50 × 1.6 mm 3 is printed on the FR-4 substrate having dielectric constant ε r = 4.4 and loss tangent (tan δ = 0.02). The four antenna elements are positioned in each corner of the PCB board in an orthogonal manner such that they can provide better isolation between antenna elements. The proposed MIMO antenna is designed to operate in frequency bands of 2.25 GHz to 2.4 GHz and 4.7 GHz to 6.3 GHz. The lower band ranges from 2.25 GHz to 2.4 GHz and covers 2.3 GHz WiBro applications while the upper band ranging from 4.7 GHz to 6.3 GHz is useful for HiperLAN and Wi-MAX applications. The proposed antenna acquires return loss less than −10 dB and isolated by more than 16 dB throughout the dual operating bands. The structure exhibits stable gain and radiation patterns. Various diversity performance metrics including envelope correlation coefficient (ECC), diversity gain (DG), and mean effective gain (MEG) are evaluated and are within acceptable limits. Full wave simulation results in terms of impedance and radiation characteristics are presented to evaluate the proposed antenna performance in an installed environment.

“…Recently, many printed antennas [8][9][10][11][12][13][14][15][16][17][18], [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] and Phase Array Antennas (PAA) [19][20] have been reported for wireless communication applications. In case of PAA power dividers plays a major role and the essential principle of the power divider or power splitter is to separate the given input signal at the input port into two or more output signals at the respective output ports with equal or unequal power distribution over the operating frequency range.…”

In this article, a compact unequal, planar Wilkinson power divider with ultra-wideband operation is proposed. The composed power divider having the size of 11.6 mm × 18.5 mm. It consists of one input and two output branches with individual resistive values. Two isolation resistors are used to provide better isolation between the two output ports. The impedance values of each transmission branch and isolation resistors is varied based on the output power division ratio i.e. (P2/P3). The ADS package simulated results of the designed unequal WPD satisfy the operating range (S11 ≤ -10 dB) from 2.5 GHz to 18 GHz and isolation are obtained over the entire frequency of operation.

“…The modern communication system widely uses multiband/wideband antennas [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21], [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45], the phased array antennas [22][23][24][25] for various commercial and defense applications. Wilkinson power divider plays a vital role in phased array antennas such as power splitting among the antenna array elements with equal amplitude and phase [1].…”

In this paper, a compact 8 way microstrip line Wilkinson Power Divider (WPD) is designed and proposed. The equal power divider con-sists of multiple multi-section WPD’s with isolation resistors. By utilizing the multi-sections concept, a remarkably increase in the band-width is observed. In the design process, RT 5880 substrate is used with the thickness of 0.8 mm and dielectric constant of 2.2 and loss tangent of 0.0004. The simulated results such as return loss, insertion loss and isolation are plotted by using ADS simulation software and obtained results show good agreement.
