Abstract—The paper represents the design and the simulation of high a high gain 2.4GHz Microstrip Rectangular Patch Antenna for wireless communication applications.
Index Terms—Microstrip Patch Antenna, Radiation Pattern, VSWR, S-Parameter
I. INTRODUCTION
Recently, The Microstrip Patch Antennas became one of the most demanding antenna based as the high demand of antennas for wireless communication systems such as wireless local area network (WLAN), cellular phone, medical applications. and satellite communication. As shown in Fig. 1, The Microstrip Patch Antenna consists of a metallic patch above a ground plane. The shape and size of patch determine the frequency of operation of the antenna and its …show more content…
11, Fig. 12, and Fig. 13 show the radiation pattern of the simulated Microstrip Patch Antenna. For the far field, theta was set from – 180 to 180 degrees with an increment of 5 degrees. Phi was varying in this analysis as shown in the figures. Fig. 11. Shows the radiation pattern at phi equal to 0, 90 degrees, while Fig. 12 shows the radiation pattern of the E-Field at phi = 0 degrees, and Fig. 13 shows the radiation pattern with varying phi from -180 to 180 degrees with an increment of 5 degrees, which showed a good variation of the power radiated by an antenna as a function of the phi as expected. Fig. 13 shows the far-field 3D polar plot of the Gain in dB, and as predicted, the gain is 3.8 dB, which is relatively small. Finally, Fig. 14 shows the far-field 3D polar plot of directivity, which the maximum gain obtainable in a particular direction. The Directivity observed with theta varies between - 180 and 180 degrees, and phi varies between 0 and 360 degrees was 6.39 dB.
