Dr.Merugu Lakshminarayana of M/s.UNISTRING TECH SOLUTIONS HYDERABAD INDIA
Advances in antenna design includes Digital Phase shifters and latest techniques in Digital phase shifter antennas
Title of the topic: Advances in Microwave Antennas & Digital Phased Arrays
The talk started with antenna parameters with an emphasis on the importance of understanding radiation pattern, directivity, and gain. Broadly nine different types of antennas cover the use in communication, radar, space, and electronic warfare systems. Antenna design requirements are explained based on type of application, required bandwidth, pattern coverage and construction of the antennas. Factors such as frequency, size, shape, location and environmental conditions which influence antenna design for applications in IoT are presented. Design of typical antennas such as wire, whip, paddle, chip, and PCB antennas used in IoT end-devices are explained. Procedure to design directional antennas like Yagi, log periodic, panel, and horn antennas required to extend the transmission range for IoT base stations is presented.
Generation of circular polarization using a single feed by corner truncated perturbation of square microstrip antennas, and asymmetric U-slot microstrip antenna are explained with examples on polarization reconfiguration applications.
Recent applications on invisible antenna film (transparent antenna layer) integrated in organic light emitting diode (OLED) touch display used for smart watch application for WiFi and Bluetooth connectivity is presented to explain integration of microwave and display technologies for IoT applications.
Briefly explained the antenna-in-package (AiP) concept for realization of efficient antennas in low-loss packaging technologies particularly at millimeter wave bands. Explained the generalized process of low temperature co-fired ceramic technology (LTTC) for AiP designs. AiP designs using LTTC technology allow effective implementation of phased arrays. Examples of LTTC based AiP antennas at 60 GHz, 79 GHz and 94 GHz are presented.
Beamforming using Butler matrix is explained for formation of multiple beams. Explained the importance and use of these antennas in cellular mobile communications. Butler matrices requirements for four beams (4x4) and eight beams are given.Keeping the digital phased arrays in view, briefly mentioned the phased array ;

D from Queen’s University of Belfast, United Kingdom on Commonwealth Fellowship during Sep 1988 and Dec 1991. Dr. Lakshminarayana joined Defence Electronics Research Laboratory, DLRL, DRDO, Hyderabad, as Scientist ‘B’ in Jan 1981. Over 34 years in DRDO, he immensely contributed towards indigenous development of antennas and microwave components for various projects; and shouldered the responsibility of execution of Electronic Warfare Projects and Programmes. Significant assignments he held include:
- As Project Director, and subsequently as Associate Programme Director, he successfully completed the indigenous development and production of Radar Electronic Warfare System for Indian Army.
- He was Project Director for indigenous development of Advanced Communication ESM Technologies, achieved some reduction of gap in self-reliance.
- He was responsible for successful flight-testing of Communication Support Measure (CSM) System on an Aircraft.
- Lakshminarayana was Programme Director of Naval Indigenous Electronic Warfare Programme.
With 34 years of R&D experience, Dr Lakshminarayana superannuated from DRDO service in April 2015 as Scientist ‘H’ (Outstanding Scientist) & Associate Director DLRL.
After retirement from Government Service, Dr. Lakshminarayana worked as Professor in ECE & Principal of Kshatriya College of Engineering, Armoor from May 2015 till Aug 2017.
