Abstract :A low-profile monopole patch antenna is proposed for wireless communication purposes, covering PCS1900, UMTS, LTE2300, LTE2500, ISM, and WLAN bands. The antenna features a novel double-crescent-shaped (D-Crescent-Shaped) patch with a partial ground plane to enhance bandwidth. Resonating at 2.4 GHz for ISM applications, the antenna, constructed on FR-4 dielectric, exhibits a proportional bandwidth of 38%, covering 1.91 GHz to 2.81 GHz. The design achieves a low-profile configuration with dimensions of 36.88×44.85 mm², featuring a thickness of 1.6 mm. The proposed antenna has a return loss of -56.1 dB and a directivity gain of 2.21 dBi. The proposed antenna, with its low-profile design, ease of manufacturing, and improved bandwidth and return loss, is well-suited for wireless communication applications across widely-used frequency ranges like PCS, UMTS, LTE2300, LTE2500, ISM, Wi-Fi, Bluetooth, and 4G LTE.
