PrintedDipoleAntennaPrinted Dipole AntennaReto ZinggAbstractIn this project a printed dipole antenna is being designed. Printed dipole antennas are of interest, when an electronic product, which is implemented on a printed circuit board (PCB) is in need of a cheap, compact antenna. This antenna has a fairly isotropic pattern, which makes it a good transmitter / receiver for portable devices. This design is based on the US patent held by Motorola [1]. It was originally designed for portable pager device for operation in the 900 MHz band. For this design the dipole as suggested by the patent was slightly remodeled and adopted to the 400 MHz band. The antenna was built and measured.Index Termsdielectric constant for a narrow trace using equation (I-3) [4]ε eff1 2ù é ε r + 1 ε r 1 ê 12 h 2 w = + 1……
