ABSTRACT
In this work, a triple-band patch antenna for wireless communication applications has been proposed. For designing an antenna with suitable resonance characteristics to cover many frequency bands simultaneously, a strip is coupled on the right side of an O-shaped patch element and ground plane has been modified with an inverted L-slot and two unequal slits. The proposed design resonates in three different bands, viz. 2.35–2.86, 3.0–4.3, and 5.64–6.85 GHz with respective bandwidths of 510 MHz, 1.3 GHz, and 1.21 GHz. Obviously, the achieved bands are suitable to cover wireless local area network/industrial, scientific and medical band, Bluetooth, Globalstar satellite phone uplink, worldwide interoperability for microwave access, International Mobile Telecommunication, intelligent transport systems, and satellite communication. The overall size of the proposed antenna is 35 × 30 mm2. The fabrication and measurement of parameters of proposed structure was carried out to verify the simulated results. Finally, complete geometrical method for the design of O-shaped microstrip patch antenna with modified ground plane is presented.
