Summary Conventional rectangular microstrip‐fed patch antennas are initially investigated numerically within the frequency band 2.0 to 2.8 GHz for Wi‐Fi applications. In order to enhance the input parameters of the underlying antennas, three prototypes are designed. A split is diagonally loaded on a conventional radiating patch to achieve a duo triangle‐shaped microstrip‐fed patch antenna in the first step. The conducting ground plane of the conventional and the duo triangle‐shaped patches is modified to design the microstrip‐fed monopole and duo triangle‐shaped monopole antennas in the second and third steps, respectively, within the frequency band of 2.0 to 7.0 GHz. Concepts of voltage and current waves as well as classical electrostatics approach solutions are used to, respectively, investigate the return loss bandwidth and the electric field radiation pattern of the proposed antennas. Numerical simulations show some relevant antenna performances such as a triple‐band, a −10‐dB return loss bandwidth of 29% , a gain of 7.5 dB, and a calculated half power beam width of 120 ° in E‐plane.
