Abstract
A printed log periodic dipole antenna (LPDA) with 3/2 curve fractal elements for size reduction and wider operating frequency bands is presented. The antenna dimension is about 123 × 181.71 mm2 reducing approximately 23.81% compared with the conventional LPDA. The radiation patterns are directional at all of operating frequencies and the average peak gain of the antenna is about 4.2 dBi. Additionally, the antenna has a wider impedance bandwidth about 135.45% supporting the operating frequency ranges are 800 MHz – 2600 MHz. They cover the standard of WCDMA 850, GSM 900, LTE 1800/2600, PCS 1900, UMTS 2100, and WLAN IEEE802.11b/g consequently.
