This study aims to design a transparent antenna that operates at a digital multimedia broadcasting (DMB) service band (174‐216 MHz) for an automotive (Hyundai K5). The transparent antenna designed on the quarter glasses located on both sides of an automotive to avoid space limitation typically placed in a roof‐mounted shark‐fin. Moreover, the use of a micro‐metal mesh film (μ‐MMF) enables the antenna to minimize visual perception and size consideration through its transparency. Two types of transparent antennas (inverted F antenna; Case1 and top‐loading inverted F; Case 2) are designed, fabricated, and measured. The transparent antennas have an average peak gain of 13.2 dBi for the inverted F antenna and 12.54 dBi for the top‐loading inverted F in the overall DMB service band. The receiving RF power (dBm) of the antenna on the quarter glasses is compared for the reliability of the signal reception in two separate locations. The power level has a difference of less than 3 dBm by location and direction.
