“…Results presented herein are particularly helpful in designing baluns using closed-form design equations irrespective of the number of conductors and the coupling factor and new equations are advisable for designing devices based on coupled lines where it is necessary to control both the magnitude and the phase of the frequency response. Accordingly, it is important to remark that this theory can be also employed to design coupled-line ring hybrids [21], artificial composite right/left handed transmission lines [22,23], ratrace couplers [24], filters [25,26], impedance transformers [27], power dividers [28], and so on. Further, in keeping with the trend toward miniaturization, the comprehensive analysis of the wire-bonded MTL is essential, even more with the recent upsurge in systems based on coupled lines [24][25][26][27][28].…”

Abstract-A novel generalized design procedure of broadband planar baluns based on wire-bonded multiconductor transmission lines (MTL) is presented hereby based on analytical equations. The proposed balun consists of two parts. The first one is an in-phase power divider, which equally splits the input power through its two outputs. The later are two MTLs with wire bonding between alternate conductors configured to introduce +90 and −90 degrees phase shift respectively, so that the balanced output signal has a 180 degree phase difference. In that sense, new closed-form design equations in order to calculate the design parameters of both multiconductor elements are obtained. These equations allow the proper dimensions of both MTLs to be computed irrespective of both the number of conductors and the coupling factor, and therefore, to determine the performance of the balun. The design procedure for wire-bonded MTL baluns has been assessed by means of full-wave electromagnetic simulations and by experimental work. In addition, the very good agreement between the theoretical results and measurements makes possible to define a time-saving design methodology.

“…The number of right-handed or left-handed frequency bands can be increased with higher order unit cell [4]. Use of wire bonded interdigital capacitor (WBIDC) in the CRLH unit-cell improves high frequency performance by reducing undesired self resonances generated in IDC at lower frequency end which leads to reach wider frequency band [5,6]. In [7], A CRLH unit cell composed with arbitrarily adjustable lumped-elements is designed in a dual metal-plane configuration in order to construct a filter with wide fractional bandwidth.…”

Abstract-Design procedure for a modified Composite Right/Left Handed (CRLH) unit cell is represented. The ferroelectric interdigital capacitor (IDC) is used as a tuned capacitor, and spiral inductor is utilized to implement inductors. A modified CRLH unit cell is attained by moving the shunt inductor of conventional unit cell to both ends with doubled values. In this manner, only one bias network would be required for each unit cell. The parameters of the designed unit cell are obtained so that the Bloch impedance to be equal to 50 Ω and the Bloch propagation constant to have one zero at the operational frequency. The operational frequency is chosen equal to 11.45 GHz, which is in the Ku-band and in middle of the up-link satellite communications. To design the modified unit cell, initially, the unit cell without a shunt capacitor is constructed. This would result in Π-model structure for which the element dimensions are varied to reach the desired values. Next, the shunt capacitor is added to the model and its length is varied until the balanced condition is achieved.

In this paper, the CRLH structures is comprised by repetition of inter digital capacitors as series and meander line inductors as shunt components into a host conventional TL exhibiting a LH band at lower frequencies and a RH band at higher frequencies.…”

Abstract-In this paper, an analytical method to characterize the frequency behaviour of Composite Right/Left Handed (CRLH) loaded printed dipole antenna is presented. One needs to determine the parameters of ungrounded reactive components realizing CRLH structures. Efficient resonant RLC circuit models based on Partial Elements Theory are presented to calculate inductance of meander line inductor and inter digital capacitor, while their capacitance is determined by Conformal Mapping Method. By using these circuit models and dispersion relation of balanced CRLH TL, negative resonance modes of antenna can be obtained. In addition, to validate the accuracy of the proposed analytical method, a prototype of the CRLH loaded printed dipole antenna is simulated, fabricated and measured.
