In this study, a novel design of a compact multiresonator‐loaded planar antenna with quad‐band working properties is proposed for wireless communication. Multiresonator‐loaded structures are employed, which include a pair of symmetrical edge resonators embedded into the edges of the monopole, a T‐shaped stub resonator extended from the ground and an inverted U‐shaped narrow slot resonator etched on the T‐shaped stub. By loading these resonators, a modified U‐shaped monopole antenna can easily produce four separate working bands while achieving a very compact size of 18 × 20 mm 2 . Based on this concept, a prototype of quad‐band antenna is designed, fabricated and tested. The measured results demonstrate that the proposed antenna is capable of operating over the frequency ranges, 2.39–2.49, 3.37–4.06, 4.73–5.46 and 5.69–6.31 GHz, suitable for wireless local area network 2.4/5.2/5.8 GHz and worldwide interoperability for microwave access 3.5 GHz applications.
