Abstract - In this review paper, a survey conducted on different techniques to introduce multi-band capability in printed
microstrip patch Ultra-wideband (UWB) antennas is presented. UWB is a promising technology for future wireless communication systems. However other lower frequency bands about UWB such as WLAN, Bluetooth, WCDMA, GSM, and GPS, etc. are important for many wireless communication systems so that the need of integrated lower frequency multi-band –UWB antenna design is essential. In this paper, we studied the different techniques proposed in the literature for design multi-band UWB antenna. Every paper from literature is described in the different subsection for better understanding of design techniques. Parametric effects are given in respective section for the particular antenna with the particular antenna structure diagram and S11 plot. After studying these techniques comparison and guideline to choose the best method for the particular design is given.

INTRODUCTION In satellite communication, in air and space crafts or in missile applications where mass, heaviness, volume, budget, performance, etc. are the main requirements of antennas. Such demands are fulfilled by the Microstrip Antennas (MSA). These antennas are subjected to stringent specifications such as small size, light weight, robustness and conformability [1]. In February 2002, Federal Communications Commission (FCC) of the United States assigned a 3.1-10.6 GHz unlicensed frequency band of UWB applications [2]. UWB system has features such as cost efficient, quiet intricacy and very high data rate for short range communication and approves short distance radio communication technology that performs high-speed communication with the speeds of more than 100 Mbps. The ultra-wideband (UWB) communication systems have received great attention from both the academic and the industrial sectors. There are two types of UWB system as follows: UWB (DSUWB) and multi-band orthogonal frequency division multiplexing (MB-OFDM). The DS-UWB proposal foresees two different carrier frequencies lower frequency band at 4.104 (3.1–5.15 GHz) and higher frequency band 8.208 GHz (5.825–10.6 GHz), while the MB-OFDM format in IEEE 802.15.3 a has an interval between 3.1 and 10.6 GHz and is divided into 14 subintervals. Each subinterval covers 528 MHz of bandwidth [3], [4]. UWB antenna is an integral part of UWB systems whereas new communication systems need a single antenna to cover multiple frequency bands Gradually, need a compact single antenna operating on multiple radiation bands including UWB range is extensively growing due to its large channel capacity, small size and stress-free integration with other wireless standards. There are two techniques reported in the literature to create multiband printed monopole antennas. In the first, a patch antenna is designed to cover the desired wide bandwidth, and then the unwanted bands are notched using one of the band notching technique. Due to the lower frequency in antenna design size of the structure increases. To create the multiband behavior, notches are introduced into the antenna [4], [5]. In the second technique, a small-size antenna can be designed to cover the highest frequency band, and for creating lower frequency bands, resonating strips are used [6], [7].
