A tunable or dual-band antenna includes a ground plane, top plane, a cage structure, first and second half-loops, and a hybrid phase shifter. The cage structure is attached to the ground plane and the top plane that includes four leg structures in electrically-conductive contact with the top plane. The top plane is one of a cross-element with four equilateral elements, a cross-element with eight equilateral elements, or a disc element. The first and second half-loops are independent from each other, located diagonally to each other within the cage structure, and support transmitting and receiving an electromagnetic field orthogonal to each other. The hybrid phase shifter shifts a frequency of the first and second half-loops to 90° from each other. The ground plane has an inner ground plane with two or more capacitors embedded therein.

Tunable antenna

One embodiment of a method and apparatus for the correction of pectus excavatum, having two arch shaped braces (), made of a rigid durable material, and connected by a flexible belt (and), each half having the ability of applying positive pressure () to the flared ribs caused by the condition. Positive pressure is to be applied to the ribs while a suction cup or other device simultaneously pulls or pushes the sternum to a natural position. Other embodiments are described and shown.
