Tahir, M. Usmam, Rafique, Umair, Ahmed, M. Mansoor, Alibakhshikenari, Mohammad, Arpanaei, Farhad and Virdee, Bal Singh (2022) Equilateral triangular slot-based planar rectangular antenna for millimeter-wave applications. In: IEEE-APS Conference on Antennas and Propagation for Wireless Communications, 5 - 9 September 2022, Cape Town, South Africa.
The design of an equilateral triangular slot-based planar rectangular antenna is presented for wideband millimeter-wave (mm-wave) applications. The front-side of the proposed antenna is composed of a rectangular patch radiator with an equilateral triangular slot fed using a 50Ω microstrip feeding line, while the bottom side of the antenna consists of a partial ground plane. To achieve maximum impedance matching in the operating bandwidth, the position of the feeding line is shifted from its normal location. The overall dimensions of the antenna are noted to be 6.5×8.5 mm 2 . From the simulation results, it is demonstrated that the -10 dB impedance bandwidth of the proposed antenna is 16.86 GHz, ranging from 22.28 GHz to 39.14 GHz, while at -15 dB, it is equal to 12.82 GHz in the frequency range of 24.18-37 GHz. The gain of the proposed antenna fluctuates in the range of 3.89-6.86 dBi with an antenna efficiency of >85%.
