This paper presents a compact dual-band monopole antenna printed on the low-cost FR4 substrate for multi wireless communication applications. The novel antenna consists of an eye-shaped patch and a semi-circular shaped slot on the half elliptical ground plane. The combination of the eye-shaped patch and a semi-circular shaped slot on the ground is used to expand the total length of the current path. This expansion improved the return loss and broadened the bandwidth of the two bands for the desired antenna. The antenna’s measurement results include multi-band frequencies such as S, C, X, Ku, K and Ka-band which covers the bandwidth requirements of WiMAX, WLAN, satellite TV, and other applications at the lower and upper-frequency band. The dimension of the antenna is (26 × 20 × 1.6) mm3 at the minimum frequency of 3.15 GHz. The proposed configuration operates at 3.55 and 19.95 GHz with a bandwidth of about 28.17% (3.15–4.15 GHz), and 147.37% (5.25–34.65 GHz), respectively for the simulation part. The measured bandwidth (− 10 dB) for S11 in the lower and upper band is about 49.71% (2.688–4.506 GHz) and 152.01% (4.933–35.861 GHz) at a center frequency of 3.657, and 20.346 GHz, respectively. The proposed antenna has a suitable radiation characteristic of 97% and 91% and a good gain of 2.97 dBi and 6.71 dBi, at the lower and upper operating band. The Vector Network Analyzer (VNA) Rhode & Schwarz ZVA40 device has been used to measure the results of the antenna and both of the software ANSYS-electromagnetic suite and CST microwave studio is used to simulate the results of the design.
