Slotted ground circular antenna for personal communication system (PCS) & broadcasting

This paper presents a broadcasting antenna design operating at 2.4 GHz frequency. The proposed antenna is designed, simulated and fabricated on FR4 substrate of permittivity 4.1 and thickness 1.5 mm. The measured return loss is 17.5 dB at 2.4 GHz whereas the simulated return loss is 36.88 dB. Thus, the fabricated & simulated antenna are in good harmony. Also the cross polarization is less than −20 dB. This antenna can be used to broadcast on several type of wireless systems that we use in our day to day life like Amplitude modulation (AM), Frequency modulation (FM) radio, satellite telephony & Global Positioning System (GPS).
