The novel miniaturized Wi-Fi logo slotted microstrip antenna application for 28 GHz is presented in this paper. The operating frequency is 28GHz-Ka-band application. The antenna is modeled by using substrate material of Rogers RT/Duroid 5880 with the relative permittivity value ԑ <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r</inf> =2.2. The proposed antenna design has return loss parameters S <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> <-10dB. The proposed design works in the frequency range: 28GHz. The radiation pattern is unidirectional and good gain is obtained. Slot configuration enhances the bandwidth of the antenna. It has a multiband response. The proposed design is simulated using HFSS (High-Frequency Simulation Software) simulator. It is a compact antenna with a size of 7x7mm a thickness of 0.8mm, a wide operational band, and good gain. The performance of the antennas in terms of return loss, bandwidth, efficiency, gain, and directivity are analyzed.
