Highly Miniaturized Triple Band Classical Patch Shaped Antenna for WLAN and WiMAX Applications

: This communication presents the novel triple-band monopole antenna in the shape of a traditional patch antenna, which is made up of a rectangular radiator with a slot and double stub loaded defected-ground structure. The antenna works on the triple bands of 2.4, 3.5, and 5.8 GHz , respectively, and it is made on the standard FR-4 dielectric material. The volume covered by the antenna is relatively small, which is 20 x 20 x 1.6 mm 3 or 0.16 x 0.16 x 0.0128 λ 30 ( λ 0 is the wavelength in free space at 2.4 GHz ). The data obtained from the measurements prove that the antenna has bandwidths of 100 MHz at 2.4 GHz, 100 MHz at 3.5 GHz, and 300 MHz at 5.8 GHz bands, respectively. It has maximum gain values of 2.91, 0.5 , and 5.5 dBi , and the antenna works efficiently on the proposed WLAN and WiMAX frequency bands. It can be posited that the suggested antenna system is a suitable option for WLAN and WiMAX band wireless applications.
