Claim 5:
6. A plasma generating apparatus, comprising
a dielectric tube configured to provide a space for plasma; and
an antenna structure surrounding an outer side wall of the dielectric tube,
wherein the antenna structure comprises:
a plurality of layer antennas comprising a first layer to Mth layer antennas,
wherein M is a natural number larger than 1,
wherein a Pth layer antenna is disposed in a Pth plane perpendicular to a center axis of the dielectric tube, where P is a natural number and 1≤P≤M,
wherein the Pth plane is different from (P+1)th plane,
wherein each of the plurality of layer antennas comprises at least two turn antennas, and
wherein a first turn of the at least two turn antennas has a first radius and a second turn of the at least two turn antennas has a second radius which is greater than the first radius, and
wherein the at least two turn antennas are disposed in same plane; and

a plurality of inter-layers capacitors comprising a first inter-layers to a Nth inter-layers capacitors,
wherein N is M−1,
wherein a Qth inter-layers capacitor electrically connects a Qth layer antenna and a (Q+1)th layer antenna in series, and
wherein Q is a natural number and 1≤Q≤N.
