Abstract

A novel design for miniaturization of microstrip patch antenna is presented for electronic multifunctional wireless communication systems. The proposed design consists of four horizontal slots of various lengths on the patch. Combination of U and L-Shaped slots is designed on the ground plane. Patch and the ground plane are shorted through a shorting pin. These practices increase electrical length of the antenna and reduce size of antenna up to 86%. The proposed antenna is operating on multiple bands and able to cover numerous applications. The reflection co-efficient is <; -10dB for all the desired bands. The proposed miniaturized antenna has acceptable gain for all the bands which is in the range of 3.5dBi to 6.6dBi. The impedance bandwidth of the miniaturized antenna is in the range of 50MHz to 650MHz. This type of reduced size antenna is very appropriate for use in compact devices like Cell Phone, WLAN and Laptop.
