In this paper, miniaturized dual and tri-band slot antenna design for various applications (GPS, MSS, cordless telephone, radio astronomy) is presented. For these proposed dual and tri-band miniaturized antennas, the first resonant is achieved by the reference slot antenna, loaded with six slits on both the end of slot which is antenna 1, the second resonant is achieved by loading with three circular loops on the middle of slot which is antenna 2, a third resonant frequency is obtained by loading with nine metallic strips on back side of the substrate which is antenna 3. The combination of antenna 1 and 2 constructs a dual-band antenna that resonates at frequencies of 1.91 and 3.32 GHz, respectively. As results, reduction in resonant frequency of 41.94% with enhanced impedance bandwidth of 117.18% is achieved for first resonance frequency in comparison with reference antenna for dual-band antenna. Then, combining antenna 1, 2 and 3 construct a tri-band antenna which resonates at frequencies of 1.55, 2.64 and 3.81 GHz, respectively. Hence, it is achieved reduction in resonant frequency of 52.88% with enhanced impedance bandwidth of 59.01% for first resonance frequency and 19.75% in reduction resonance frequency for second resonance frequency in comparison with reference antenna.

In this article, miniaturization of dual‐band slot antenna design for GPS, WLAN and amateur radio applications is presented. The proposed dual‐band miniaturized antenna is achieved using slits, rectangular split ring and metallic strips fed by 50 Ω microstrip feed. The first resonant frequency is achieved by loading reference antenna with eight slits that is antenna 1 and the second resonant frequency is achieved by loading with one center slits and rectangular split ring that is antenna 2. Dual‐band antenna is achieved by loading reference slot antenna with nine slits and rectangular split ring which resonates at frequency of 1.52 and 3.03 GHz respectively. As a result, it is achieved 53.79% reduction in first band resonant frequency with 76.07% improvement in −10 dB bandwidth and 7.90% reduction in second band resonant frequency compared to reference slot antenna. Further, this dual‐band antenna is miniaturized by metallic strips which are placed on the bottom of the substrate. This results in 61.39% reduction in first band resonant frequency with 32.07% improvement in −10 dB bandwidth and 26.13% reduction in second band resonant frequency in comparison with reference slot antenna topology.
