Abstract
This paper introduces a simple, E-shaped slot loaded wideband microstrip patch antenna with a metallic cavity. The antenna design is an improvement from previous research and it is simulated using HFSS 13 software. The performance of the designed antenna was analyzed in term of bandwidth, gain, VSWR, and radiation pattern. What does the substrate use is air. The results show the wideband antenna is able to operate from 190MHz to 230MHz frequency band with optimum frequency at 210MHz, and the 3-dB radiation beamwidth of the E and the H plane at the 210MHz are 61° and 51°. However, the 3-dB radiation beamwidth of the E and the H plane at the 210MHz can be adjusted to 70° by using a metallic cavity.
