| Annotation | A corner truncated square shaped monopole microstrip patch antenna with slotted spur line in feeding path is designed and analyzed in this article. The proposed antenna operates in a super wide band range of 1.9 to 25.7 GHz with a rejected band of 8.7 to 10.6 GHz. The fractional bandwidth of 172.4 % is achieved with this design. The optimum dimension of the spur line has been taken for generation of the notched band at desired frequency. Due to the rejected band, the designed antenna will be working for any applications within the super wideband range except amateur radio operation and amateur satellite operations; thus, it shows the novelty of the paper as no such antenna design for this application has been reported earlier. The antenna is very small in size with the overall electrical dimension of 0.13 0.11 0.0096, where is the wavelength of the lowest operating frequency 1.9 GHz. The complete size of the antenna is only 21 18 1.524 mm3. The peak realized gain of the antenna is 5 dBi within the operating band and the gain at the notched frequency is minimized to – 6.5 dBi due to the spur line. The antenna is designed and simulated in commercially available software (HFSS). |
