Abstract
In modern wireless communication, multiband microstrip antennas are widely equipped in mobiles, laptops and other portable devices due to their advantages like the small size, light weight, low cost and easy integration with planar structures. Moreover, the research evolution in these antennas, which are required for portable wireless communication system applications, is advancing day by day. So, it is essential to notice the research and improvements happening in the area of multiband antennas for the intended applications. The main objective of this paper is to discuss numerous multiband antennas for GSM, Wi-Fi and WiMAX 2500 applications. The GSM applications cover GSM 900, GSM 1800 (DCS 1800) and GSM 1900 (PCS 1900) bands while the Wi-Fi applications cover 2.4GHz and 5.8GHz bands. Sometimes, these antennas also operate in various bands of GPS, LTE 2300, LTE 2600, UMTS and WiMAX 3500 along with the GSM, Wi-Fi and WiMAX 2500 bands. This paper presents various conventional microstrip antennas that include single, dual, triple and multiband antennas. In this, it reports various shapes of slots and technique to achieve multiband antennas and also explains merits and demerits of all antenna. Finally, this paper helps to explore and design suitable multiband antennas for the required applications.
