Deep Body Microwave Hyperthermia Device for Personal Uses from Focused Microwave Thermotherapy System

This paper introduces the deep body microwave hyperthermia device with 4 patch antennas for personal uses which heals pains or inflammations of arm and legs. The focused microwave thermotherapy system is introduced as background to create the heat spreading algorithm by phase rotation of 360 0. The deep thermal spreading effects are predicted by its work simulation which reaches 42.8 °C from 37°C after 20 minutes. Specifications of device are also introduced which is 925 MHz operating frequency and 1W typical total power etc.

I. Introduction

Treatment for degenerative musculoskeletal disorders includes thermal therapy, ultrasound therapy, and high frequency therapy. Recently, intensive microwave heat therapy is being studied [1]. In some cases of degenerative musculoskeletal disorders, a concentrated heat is required. However, there are other cases like many problems associated with excessive exercise, muscle pain caused by overwork, plantar fasciitis, and joint pain. In these cases, hyperthermia instead of concentrated heat should be applied to a wide range of areas up to the core. Fig. 1.
