A Survey on Ultra Wideband High Directivity Low Profile Antenna

Antenna converts electronic waves into electromagnetic waves. In the present days of communication the antenna has to be versatile which can have wider applications. This is possible if the antenna is having wide range of operating frequency. At the same time to achieve high range of communication the antenna has to be very high directive. Thus a compact antenna with very high directivity and wide operating range of frequency is the need for many wireless communication systems & defence (RADAR, Unmanned Aerial Vehicle etc). This paper presents a survey on ultra-wideband high directivity low profile antenna. In this crowded world, wireless communication plays a prominent role in keeping us to stay connected, antenna is an important part of wireless communication system, after the extensive use of wireless communication, new growing ultra-wideband technology with advantages of less power consumption, less complexity, low cost, high data transmission, thin profile, conformability is used. Further ultra wide band micro strip patch antenna with improved characteristics of thin profile, high directivity becomes prominent feature of wireless communication. This paper discusses the existing survey works related to the topic.
