Wearable Tunable Printed Antennas for Medical Applications
Communication and biomedical industry is in continuous growth in the last decade. Low-profile compact tunable antennas are crucial in the development of wearable human biomedical systems. Tunable antennas consist of a radiating element and of a voltage-controlled diode, varactor. Varactor diodes are semiconductor devices that are voltage-controlled variable capacitance. The radiating element may be a microstrip patch antenna, dipole, or loop antenna. The antenna resonant frequency may be tuned by using a varactor to compensate variations in the antenna resonant frequency.
Microstrip antenna resonant frequency is altered due to environment condition, different ...
