A $V$-Band Switched Beam-Forming Antenna Module Using Absorptive Switch Integrated With 4$\,\times\,$4 Butler Matrix in 0.13-$\mu{\hbox {m}}$ CMOS

In this article, we present a new wideband hybrid coupler for millimeter-wave applications realized in the BiCMOS9MW 130-nm process from STMicroelectronics. The fabrication of two slightly different couplers demonstrates the wideband performance associated with miniaturized size, thanks to the use of meandered transmission lines and lumped capacitors. The best coupler provides a 210-dB matching bandwidth of 42% with an insertion loss of 0.6 dB and a phase shift of 88 at 60 GHz. The amplitude imbalance and the phase imbalance stay, respectively, within 61 dB and 65 over 27 and 36%. These state-ofthe-art results are compared to recently published results obtained with comparable hybrid couplers. V C 2014 Wiley Periodicals, Inc.

“…Many BFN configurations have been designed, such as Blass Matrix [2], Rotmans Lens [3], and Butler Matrix (BM). The SBSA studied using BM BFN as the basic component has received so much attention [4][5][6][7][8][9] due to its simplicity and ease of implementations and has been chosen for this research work. It can support beam switching operation and allows 1-D switching [4,[10][11][12] at ±45ᵒ and ±135ᵒ.…”

This paper presents a low cost, two dimensional (2-D) millimetre wave switched-beam array antenna attained by feeding a planar array antenna with a cascaded 4 x 4 Butler matrix (BM) beam forming network (BFN). To minimise the surface current, ensure low cost and ease fabrication, a single layer has been implemented. The prototype is fabricated and measured results presented. According to the results, the maximum beam scanning of from -41ᵒ to +42ᵒ, and a maximum antenna gain of 13.8 dBi are obtained in the x-z plane. While the maximum beam scanning of from -43 ᵒ to +41 ᵒ and the maximum antenna gain of 13.7 dBi are realized in the y-z plane. With a single pole multiple throw switches, switching the various matrix terminals on the BM in the horizontal plane gives the beams in the x-z plane, while switching the BM in the vertical plane gives the beams in the y-z plane. All experimental and numerical results are in good agreement which can be practically used for fifth generation (5G) wireless systems.

“…To date, CMOS‐integrated single‐pole–double‐throw (SPDT), single‐pole–four‐throw (SP4T), and double‐pole–four‐throw (DP4T) switches have been reported in the previous studies . Shin et al and Choi et al reported 4 × 4 crossbar and beam‐forming Butler switches, respectively. Another CMOS beam‐forming Butler switch of an 8 × 8 matrix was discussed in the study of Cetinoneri et al Recently, a 65‐nm DC‐17‐GHz CMOS single‐pole–eight‐throw (SP8T) switch was reported in the studies of Azhari et al and Song et al, in which two SP8T switches were utilized to replace a conventional mechanical switching matrix in a radar‐based tumor detection system to make a compact, low‐power, and portable system.…”

An ultra-wideband 2-to 12-GHz transmit/receive (T/R) double-pole-eightthrow (DP8T) switching matrix is developed with a 65-nm complementary metal oxide semiconductor (CMOS) process for a radar-based breast cancer detection system. The measured average insertion losses are 5.2, 7, and 10.6 dB at 2, 6, and 12 GHz, respectively, with input and output matching bandwidths of 2 to 12 GHz and a third-order input intercept point (IIP3) of 31 dBm at 8 GHz. The power consumption is less than 1 mW for a 1.2-V power supply. To the best of the authors' knowledge, this is the first reported DP8T CMOS switching matrix to replace the conventional mechanical switch to control a portable radar antenna.
