Design of Ultra Low Profile Inverted L Antenna Composed of CPW Printed on PET Sheet for IoT Application
Keywords:inverted L antenna, IoT, low profile antenna, printed antenna, polyethylene terephthalate sheet
The ultra low profile inverted L (ULPIL) antenna on a rectangular conducting plane is located above the lower conducting plane and numerically analyzed for the application of IoT. The coplanar waveguide (CPW) is inserted within the antenna element. The antenna element is printed on the polyethylene terephthalate (PET) sheet. The shift of the resonant frequency of this antenna is small due to the existence of lower conducting plane. The influence of the existence of the lower conducting plane can be neglected when the distance between the ULPIL antenna and the lower conducting plane is longer than 6 mm (0.049 wavelength). Therefore the ULPIL antenna may be promising for the IoT application.
