The simulated yagi uda antenna has wide bandwidth of 1.8 GHz with return loss of <-10 dB.ДЇig. 3 shows the return loss and bandwidth of the Yagi Uda antenna that operates at a frequency of 5.2 GHZ. 2: Measured and Simulated gain of proposed Yagi-Uda antenna.ДЇig. Antenna gain is the ability of an antenna to direct radiations in a particular direction.ДЇig. 2 shows gain of 7.05 dB (9.19 dBi) of the Yagi Uda antenna at 5.2 GHz.

The proposed antenna is simulated using HFSS simulation software and various parameters such as Bandwidth, Return loss, VSWR, Gain, Directivity and Radiation efficiency are observed.ДЇig. So that maximum radiation takes place in endfire direction.ДЇig. The Yagi-Uda antenna is one of the most popular endfire antennas but the microstrip structure usually radiates in all the direction thats why a metal plate is placed at a distance of 15 mm to reflect the power back to the dipole. To enhance the gain of antenna coupling structures are placed between the reflector and the driven element. It was noticed that the use of second director does not give the appreciable increment of gain, but leads to increase the size of antenna only. The driven dipole is built on both sides of the substrate and connector with characteristics impedance of 50 is used for providing the excitation to driven dipole of antenna. The metallization is done on the bottom plane that will act as a truncated micro-strip ground plane, which serves as the reflector element for the antenna and the parasitic director elements is placed on the top plane simultaneously which directs the antenna propagation toward the end-fire direction, and acts as an impedance matching element.

Truncated ground plane is used to maximize the antenna gain, if truncated ground plane is not used then a power given to the driver dipole element will not radiate and return to the ground plane itself. The design consists of one director element, a driven element and a ground plane acting as a reflector. As can be seen from the figure, the Yagi-Uda antenna was built on a FR4 substrate (r = 4.4) with the thickness of 1.6 mm. The design of the proposed antenna is shows in Fig.

Where is the wavelength in meters, c is the velocity of light in free space (3x108m/s), f is the operating frequency in GHz. The structure consists of driven dipole, director and a truncated ground plane act as a reflector, thus eliminating the need of reflector, which are placed on the FR4 substrate with dielectric constant (r) of 4.4 and substrate height (h) of 1.6 mm and connector with In this project, Yagi-Uda antenna is designed at 5.2 GHz to achieves high gain and low backside radiations, which is used in recent WLAN and is being considered for next generation mobile network (NGMN) applications. presented a coplanar waveguide-fed Quasi-Yagi antenna at X-band. presented a microstrip-fed Quasi-Yagi antenna with a moderate gain of 35 dB at X-band. presented a Yagi-Uda antenna with one director, a truncated ground plane acting as a reflector and with a simplified feeding structure. designed a Yagi-Uda antenna which achieved a directivity of 9.3 dB at 24 GHz. In order to enhance the antenna characteristics the driven element, reflector and parasitic element of yagi-uda antenna are arranged on the same substrate. Growth in communication system requires a directional beam antenna for many such applications radar, medical, industrial and wireless communication and yagi-uda antenna is used for above application because it is a uni-directional antenna which means that it radiates greater power in one direction consequently reducing the interference from all other sources. Yagi Uda antenna is widely used owing to various advantages like ease of fabrication, low cost, high gain, simple structure etc. It consists of driven dipole (Driven Element) and a set of parasitic elements (reflector and one and more directors) are arranged on the same substrate. In 19 ShintaroUda and Hidetsugu Yagi were discovered an antenna which is known as Yagi Uda antenna The general rules of design for a Yagi Uda antenna operating at 5.2 GHz is given by Keywords Yagi-Uda antenna, Reflector, Director, Driven dipole, FR-4, HFSSД¬haracteristics impedance of 50 is used for providing the excitation to driven dipole of antenna.
