A NOVEL HIGH-GAIN DIRECTIONAL LENS ANTENNA FOR TERAHERTZ BAND

High Gain Conformal Tri Band Antenna

In this paper, a tri-band E-shaped microstrip patch antenna is presented for SHF and microwave data links. The proposed antenna has symmetrical properties and has been designed by forming E-shape structure on substrate with Wave guide feed. It radiates for three bands having two bands in SHF and one in lower EHF frequency bands. It is demonstrated that the fabricated antenna offers improved val...

Novel Triple Band Helical Antenna for Gain and Bandwidth Enhancement

In this paper a design of triple band one turn helical antenna without ground plain for center frequency of 2.4 GHz, 3.6 GHz, and 5.4 GHz is discuss. These frequencies are selected such that the antenna radiate for continuous band of 2 GHz to 6.8 GHz frequency with variable gain. The purpose of this novel design is to enhance the gain as well as bandwidth. The triple band is achieved by three c...

High Gain Planar Antenna Structures for Ka-band Applications

design of a novel directional microstrip-fed super-wideband antenna

in this paper, a novel directional super wide band micro strip antenna based on a simple and new geometry has been proposed. the antenna exhibits the widest bandwidth ever reported to the authors’ knowledge from 50 ghz to 200 ghz. its radiation pattern is approximately steady in the frequency ranges of 50 ghz to 200 ghz. the antenna consists of a club-like radiating patch, a combination of thre...

Development of the C-Band Directional Antenna

Army Ground Vehicles are equipped with various antennas that span over a large frequency range of operation. Many of these antennas often encounter physical obstructions from other equipment on the platform. A typical omnidirectional antenna for example, would have difficulty maintaining its performance due to unwanted blockage from these obstructions. In order to overcome the issues of overcro...
