The new technical developments in wireless networking devices require
simultaneous operation at different frequencies for different applications such as LTE,
IoT, wi-fi, etc. To achieve the compact microchip scale, this chapter explores the
numerous key features of miniaturization techniques in basic antenna with advanced
fractal arts. Fractals are a subset of non-Euclidian geometry. The larger bandwidth with
multi frequencies is a key characteristic of antennas that have a fractal design in them.
The defective ground design successfully overcomes the demerits associated with
fractal design in the antenna. Modern-day applications like IEEE802.16 (Wi-Max,
WLAN), Mobile operating bands (GSM, LTE), BT, etc., are covered in this chapter.
Keywords: Defected ground, Fractal geometry, Multiple inputs, Multiple outputs,
Wireless communication.
