摘要: A multiband PIFA (planar inverted-F) antenna. preferred embodiment makes use of a spiral slot. The slot is formed to cause multiple frequency dependent nulls in the antenna's electric field modal distribution. antenna has single element patch radiator on dielectric support an inverted-F relationship with first ground plane. may be part device housing or internal board, e.g., PCB board. includes feed made location relative ensure that portions enclosed by are fed as series extension another portion said radiator. According embodiment, from conductive sheet, plating deposit along shorting post and feed. majority its surface area primary plane remaining surfaces define, generally perpendicular plane, extending edge second tab add extend, for example, third
