A compact quarter-mode substrate integrated waveguide (QMSIW) based self-quadruplexing antenna is proposed for compact RF front-ends. The QMSIW based self-quadruplexing antenna has four unequal resonators resonating at the Industrial, Scientific and Medical (ISM) band (2.45 GHz), fifth-generation (5G) band (3.5 GHz), Wireless Local Area Network (WLAN) band (4.9 GHz) and Wireless Fidelity (WiFi) band (5.4 GHz). All four resonators radiate through the open-ended wall of the QMSIW resonator and the arc-shaped slot inside the cavity. By properly optimizing the locations and dimensions of the resonators, higher isolation ( > 29.9 dB) is gained. In fact, all four resonators operate on a common grounded substrate with negligible interference. A dummy rectangular device is used to keep the PCB and antenna in it to measure S-parameters and radiation properties. The proposed antenna has lower circuit size (0.23 λ2g ), reasonable gain ( > 3.85 dBi), high efficiency ( > 82.7 \%), and high isolation ( > 29.9 dB). Based on the above attributes, it is a good candidate for compact RF Front-ends.
