| Abstract: | A compact coplanar waveguide radiator is formed by two ground plane and a slotted central signal strip. The radiating patch is printed on FR4 substrate 1 mm thick. The circular slot on the central strip improves the bandwidth and decreases the return loss. The measured results show that it covers 4.25–7.95 GHz bandwidth with −24.80 dB return loss at a resonance frequency of 6.00 GHz. The fabricated radiator produces nominal value of co-pol at the resonance frequency. The Z-parameter of the proposed radiator is correlated with 50 Ω matching condition. The magnitude of voltage standing wave ratio at 6.00 GHz tends to unity, which implies that the reflected signal is zero and leads to a perfect matching radiator. The measured average gain and radiation efficiency are 2.44 dBi and 94.50%, respectively. The fabricated radiator covers 5.20/5.80 GHz wireless local area network (WLAN), 5.50 GHz worldwide interoperability for microwave access (WiMAX), 5.80 GHz industrial, scientific, and medical (ISM) band, 5G sub 6 GHz band, and 5 GHz wireless fidelity (WiFi) bands.
