Abstract: A surface wave antenna operating in the 2.4 GHz band and efficient for launching surface electromagnetic waves at metal/dielectric interfaces is presented. The antenna operation is based on the strong field enhancement at the antenna tip, which results in efficient excitation of surface waves propagating along nearby metal surfaces. Since surface electromagnetic waves may efficiently tunnel through deeply subwavelength channels from inner to outer metal/dielectric interface of a metal enclosure, this antenna is useful for broadband radio communication through various conductive enclosures, such as typical commercial Faraday cages.<br />8 pages, 8 figures
