Our goal is to develop THz module on chip to visualize bone grinding atthe early stage so that arthritis can be visualized and treated early. A criticalcomponent of such module is antenna. A compact 4 by 4 beamformingantenna array for biomedical application is presented in this paper. Weare proposing a novel antenna which is in the form of a circular ribbonshape with a gold patch. Gold material for the patch is used to enhance itsconductivity and to cut down backward radiation. Differential port pin usedto increase the bandwidth. Au-posts are finally used for output connection.The proposed antenna operates over the frequency band from 201 GHz tomore than 228 GHz. Directivity and gain of the proposed antenna are 13dB and 7 dB respectively. This makes it applicable for imaging systemsbecause of the frequency band for biomedical imaging. Index Terms—Beamforming antenna, antenna array, Advanced design system (ADS),Biomedical imaging.

“…In this paper, we are proposing two different kinds of onchip GaN antennas for improvement in the radiation efficiency and gain using novel element design, the first one is beamforming array antenna (BFAA) and second one is multiple port wideband antenna (MPWBA). The true advantage of on-chip antenna can be attained by its realization in GaN chip process so that the circuits can be integrated with the back end digital blocks on the same chip because GaN will provide low loss, wide bandwidth, favorable linear polarization, and temperature stability [8][9][10] .…”

A novel architecture for Wireless Power Transfer (WPT) module usingmonolithic components on GaN is presented in this paper. The design ofsuch a WPT module receives DC power from solar panels, consists ofphotonic power converter (PPC), beamforming antenna, low pass filter,input matching network, rectifier, output matching network and logic circuit(off-chip) which are all integrated on a GaN chip. Our WPT componentsshow excellent simulated performance, for example, our novel beamforming antenna and multiple port wideband antenna have a gain of 8.7 dBand 7.3 dB respectively. We have added a band pass filter to the rectifieroutput which gives two benefits to the circuit. The first one is filteringcircuit will remove unwanted harmonics before collecting DC power andsecond is filter will boost the efficiency of rectifier by optimizing the loadimpedance. Our proposed rectifier has RF-DC conversion efficiency of74% and 67% with beam-forming antenna and multiple port wide bandantenna respectively. Our WPT module is designed to charge a rechargeablebattery (3 V and 1 mA) of a radio module which will be used between twoantennas in future 5G networks. We believe our proposed WPT modulearchitecture is unique and it is applicable to both microwave and millimeterwave systems such as 6G.
