Abstract
In this paper, a new miniaturized compact dual-band microstrip slot antenna is presented. To achieve the dual-band characteristics, two adjunct partial arc-shaped small slots are joined to two main circular slots embedded in the ground of the antenna structure. With a reduced size of 30 × 28.5 × 0.8 mm3, the proposed antenna presents a dual-band characteristic. The design is optimized using a High Frequency Structure Simulator (HFSS) followed by experimental verifications. An impedance bandwidth, for S11≤10 dB, that covers the 1.8 GHz and 2.4 GHz bands is accomplished, which makes the proposed antenna basically suitable for hand-held devices and medical applications. More applications such as digital communication system (DCS) 1.71–1.88 GHz, personal communication services (PCS) 1.85–1.99 GHz, Universal and mobile telecommunications system UMTS 1.92–2.17 GHz, Bluetooth 2.4–2.5 GHz, and Wi-Fi 2.4–2.454 GHz, Industrial Scientific and Medical radio frequency (RF) band ISM-2.4 GHz, Wireless Local Area Network (WLAN-2.4)are possible by simply changing one of the geometrical antenna dimensions. The antenna is characterized by stable radiation patterns as well.
Highlights
Conventional microstrip antennas have the attractive features of a low profile, light weight, ease of analysis and fabrication, and ease of integration into microwave devices
A literature survey shows that planar slot antennas are promising candidates multi-band characteristics are in great demand for various applications such as wireless local area to realize broadband or multi-band functions cover up multi-standard services
We present the technique of introducing arc-shaped slots inand the obtain antenna a small partially etched round these two main slots to realize the small dual-band function structure to realize a new high gain miniaturized dual-band radiating antenna
