New Design Approach of a '2.4 GHz' Slotted Rectangular Patch Antenna with a Wideband Harmonic Suppression

摘要

The designing of an antenna with a wideband harmonic suppression will lead to enhance the overall antenna performanceefficiency as well as neglecting electromagnetic noises. A “defective ground superimposing” or a Y-slot construct confederatedwith a ring hopefully meets an effective approach that is exploited in removing high level of harmonics in the designprocess. A “2.4 GHz” rectangular U-slot microstrip patch antenna with an active antenna radiators and harmonic suppressiongrid has been presented. The paper focuses on the geometrical of active integration antennas to achieve efficient filtering andeasy attenuation of unwanted harmonics. Further, an embedded empirical antenna with a high-order harmonic suppressionhas been suggested. This is followed by a “complementary opening recoiled construct cell”. The proposed approach wasdeveloped to control the antenna harmonics at center frequency of " 2.4 GHz ." The simulation sketches show that the reflectioncoefficient of multiple harmonics had an effective suppression up to 3.2 dB without any effect on the resonant frequency.The radiation patterns at high suppression levels of harmonics are within the range (13.92–15.2 dB) for both E-plane andH-plane. Further, the designed antenna bandwidth at the resonant frequency is (85 MHz) . Finally, the proposed antenna withDGS had return losses and antenna gain of (−23.15 dB; 8.25 dB), respectively.
