1. A device comprising an antenna configured for delivery of energy to a tissue, wherein a distal end of said antenna comprises a center-fed dipole component comprising a rigid hollow tube encompassing a conductor, wherein said conductor has a proximal end and a distal end, wherein said distal end of said conductor engages said rigid hollow tube via connection with the center of a conductive material that spans across said rigid hollow tube thereby preventing said distal end of said conductor from contact with said rigid hollow tube, wherein said distal end of said conductor does not extend beyond said conductive material thereby preventing said conductor from contact with said tissue, wherein said hollow tube has a diameter equal to or less than a 16-gauge needle, wherein said energy is microwave energy.
