Design a 64-QAM load modulated transmitter antenna array with high data transfer capability and better energy efficiency for mmWave applications.

Millimeter wave (mmWave) is the best way to handle high data rate requirements in this era of 5G communications. High data rates could be achieved by complex modulation schemes such as QAM and OFDM. However, both make the transmitted signals with high peak-to-average power (PAPR). PAPR can be lowered with multi-carrier transmission, amplitude clipping, and interleaving to mitigate the issue of inter-channel interference. Getting a lower PAPR costs data, signal power, and processing time. In the traditional radio frequency (RF) transmission, QAM is generated by changing the input voltage to the transmitter. The load modulator (LM) is an RF circuit with high-speed RF switches. It delivers the desired transmitted signals at the antenna inputs by changing the impedance of the load modulator instead of modulating the voltage source. Innovative mmWave technology will use 64-QAM modulation and a phased antenna array to maintain the line of sight during communication. This research will boost the mmWave technology effectively. A cost-effective mmWave wireless network is needed for climate change and devices with low latency. This research plan aims to improve the high-end modulation of the transmitter while lowering the costs of making it.
