This paper presents a design of 60-GHz exponential tapered slot Vivaldi antenna-on-chip (AOC). The antenna is designed using standard 0.18µm six metal-layers CMOS technology. A double-Y balun feeding structure is used to make transition from coplanar waveguide to slot-line. Two techniques are investigated for improving antenna radiation properties. The first technique incorporates equal corrugations on the edges of exponential flaring section and other on the backed-edge of antenna to enhance the antenna gain. Second, a planar arc reflector is constructed using metal vias between M6 and M1 to inhibit the back lobe, contributing to the enhancement of gain and efficiency. The overall antenna size is compact and equal to 785µm×930µm. The influence of the antenna position on the radiation properties is also studied. The proposed antenna offers endfire radiation pattern with a simulated peak gain and a radiation efficiency of -0.4 dBi and 32%, respectively.

“…Comparing with the four or higher order Marchand balun, Double-Y balun has only a little higher or no complexity of design. As a result, double-Y balun is widely used in mixer [1] [3] and ultra-wideband antenna or pulsed antenna [4]- [7], such as V dipole, vivaldi antenna, complementary spiral antenna, et al Beside, double-Y balun can also help transition between different type of transmission lines which increases design freedom. In a word, double-Y balun is a kind of interesting and important microwave component.…”

“…CPW FPG -CPS double-Y balun is a revised version with better balance by introducing bond wire bridge between the two ground plane of Coplanar Waveguide, but the bond wire also introduces undesired parasitic effects degrading the high frequency performance of double-Y balun [6]. The upper frequency limitation of microstrip to CPS double-Y balun referred in [7] can reach 13GHz.…”

Double-Y balun is a kind of printed balun with ultra wide bandwidth, which can also realize transformation from different sorts of printed transmission lines and has been widely used in wideband mixer and ultra-wideband antennas. This paper researched on some elements that influent the upper frequency limitation of double-Y balun in practical engineering and presented a design of double-Y balun transition from microstrip line to coplanar strip line (CPS) with pass band up to 18GHz. The design also included a Microstrip impedance transformer as this design is to feed a 100 vivaldi antenna. The VSWR of whole component was less then 1.5 and insert loss 2dB in a bandwidth of over 1: 18.

“…Design of baluns has been the subject of extensive research during the past few decades and different structures have been proposed such as lumped element designs [1], rat race hybrid [2], marchand balun [3], double Y balun [4], integrated circuit structures [5], and also three dimensional structures such as substrate integrated waveguide (SIW) structures [6]. Planar baluns are among the most utilized structures because of their ease of fabrication and good performance.…”

In this paper a new single layer BALUN is presented that covers the frequency range of 200MHz to 10GHz. The structure is composed of a two stage Wilkinson power divider followed by a wideband current flipping structure. Full wave simulations as well as measurements show that an amplitude imbalance of below 0.2dB and a phase imbalance of less than 5 degrees is achieved by this BALUN from 1.5GHz to 10GHz. Maximum phase and amplitude imbalance are 12degrees and 2dB respectively. The structure is very low loss with maximum insertion loss of 2dB and is matched at all the three ports with the maximum reflection coefficients of less than -10 dB in most of the bandwidth. The coupling between the two equally powered output ports is less than -10dB and the total length of the structure including the transitions to the connectors is 6.5cm.
