A transparent dual‐band monopole (Inverted‐F) antenna using a micro‐metal mesh film (μ‐MMF) designed on the rear glass of an automobile (Hyundai K5) is presented. This design allows the optically transparent antenna to be installed in a wider space, thus overcoming the space limitation typically posed by roof‐mounted shark‐fin antennas. It can also reasonably solve the problem of low reception sensitivity and radiation interference from antennas operating in other service bands. The antenna is a combination of two simple monopoles operating in the frequency modulation (FM) (88–108 MHz) and the digital media broadcasting (DMB) (174–216 MHz) service bands. Measured reflection coefficients (S11) of the transparent antenna using μ‐MMF are under −6 dB (VSWR 3:1) in both the bands, and the radiation pattern shows directive patterns to the outward direction from the car; the average peak gains in the XY plane are 1.1 dB in the FM service band and 8.8 dB in the DMB service band.

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.
