Abstract: A folded dipole patch antenna for use in a hyperthermia applicator is described. The antenna includes a dielectric circuit board, and a folded dipole microstrip antenna. The dielectric circuit board has a top side and a bottom side. The folded dipole microstrip antenna is formed on the top side and includes two meander paths mirror each other. A pair of parallel metallic strips is located on the bottom side. A coaxial feed port is connected to the pair of parallel metallic strips. The antenna is configured to resonate in a frequency range of about 434 MHz upon application of an input signal at the coaxial feed port. The folded dipole patch antenna has a small size and does not require an impedance matching circuit. The hyperthermia applicator is configured to emit microwave energy toward a target tissue within a human body.

Abstract: A shared aperture multi-band antenna is described. The antenna includes a dielectric circuit board, a folded dipole microstrip antenna, and a lumped inductor. The folded dipole microstrip antenna is formed on a top side of the dielectric circuit board. The microstrip antenna includes two meander paths. The two meander paths enclose a shared aperture therebetween. The lumped inductor is inserted across a first gap near the third edge. A first pair of parallel metallic patches, a second pair of parallel metallic patches, and a third pair of parallel metallic patches are located on the bottom side. The antenna resonates in a dual band frequency range comprising a first resonance band in a range of 0.4 GHz to 0.6 GHz and a second resonance band in a range of 4.7 GHz to 5.8 GHz upon application of an input signal at both a first feed port and a second feed port.
