“…Foster first canonical form is used to model the proposed dipole antenna (because proposed dipole antenna is an electric antenna). The dipole response can be represented by the series combination of parallel RLC circuit (represented by L2, C2, and R1 in Figure A) and series LC circuit (represented by L1 and C1 in Figure A) . The feed gap is modeled by capacitance C3 in parallel to dipole equivalent.…”

“…The dipole response can be represented by the series combination of parallel RLC circuit (represented by L2, C2, and R1 in Figure 3A) and series LC circuit (represented by L1 and C1 in Figure 3A). 18 The feed gap is modeled by capacitance C3 in parallel to dipole equivalent. Figure 3B shows a comparison of the reflection coefficient obtained from the Full wave EM simulation (CST studio suite) and equivalent circuit (simulated using Keysight advanced design system [ADS]) of the antenna.…”

A circularly polarized antenna is realized using a discontinuous ring dipole. With the introduction of p‐i‐n diodes, it has been possible to achieve polarization reconfigurability in the antenna. The antenna is fed by a tapered feed line, which also acts as a balun and biasing structure. The sense of rotation of the electric field vector (left‐hand or right‐hand) can be controlled by switching the states of the diodes. An equivalent circuit of the antenna is proposed, which has been used to compute the input reflection coefficient of the antenna. The performance of the antenna is verified by comparing the simulated results with the measured results. It has been observed that the antenna has 8.56% overlapping CP bandwidth (a common bandwidth for |S11| ≤ −10 dB and axial ratio, AR ≤3 dB) from 5.03to 5.48 GHz. A measured gain of 3.61 dBic is obtained for all polarization states. The proposed antenna can be used for the 5.2 GHz Wi‐Fi application.

“…However, these antennas require a finite ground plane, defeating the desired properties of low profile and conformal nature of a printed antenna [5]. A tapered feed printed strip dipole with parasitic metal strip near the feed point to achieve wide bandwidth is reported by Behera and Harish [6]. Here the bandwidth is limited to 66% with return loss (S 11 ) ≤ −10 dB.…”

In this paper, the design of an asymmetric wideband printed dipole antenna is presented along with measured results. The wide bandwidth covering 0.8-4 GHz is achieved using inset feeding technique. This paper also presents the techniques for achieving good omnidirectional radiation patterns over the wide frequency band with deviation from omni-directionality within ±2.5 dB. This design offers more than 5 : 1 impedance bandwidth (for VSWR ≤ 2.2 : 1), with good radiation efficiency and omnidirectionality. The comparison study of symmetrical and asymmetrical printed dipole antennas with and without inset feed is presented in this paper. Thus, the proposed antenna finds a wide range of applications in trans-receive modes in today's wireless devices.

“…GHz (2500-2690/ 3400-3690/ 5250-5850 MHz) bands, many attempts have been made to widen the bandwidth of the printed dipole antennas including inductively-loaded dipole, the double-sided printed dipoles and series-fed two-dipole [4][5][6][7][8]. Different element geometries have also been evolved to improve operating impedance bandwidth such as circular, elliptical, bowtie and so on [9][10][11][12].…”

A compact printed dipole antenna with enhanced impedance bandwidth is proposed for wireless applications in this paper. This antenna consists of a pairs of radiation metal arms, a microstrip-to-slot transition and a linear tapered slot.The linear tapered slot is etched into the center of the radiation metal arms. With this structure, the bandwidth of a conventional dipole antenna is improved significantly. A prototype of the antenna is fabricated and tested for demonstrating the effectiveness of the design. The measured results show that the proposed dipole antenna can achieve a gain of 1.9-4.SdB across a 101.7% measured bandwidth from 2.08 GHz to 6.38GHz.
