Circular Triple T-shaped Slotted Pattern Reconfigurable Antenna for Ultra-Wideband Applications
摘要
This communication examines a multi-directional, compact pattern reconfigurable microstrip antenna. The proposed antenna has a straightforward design and is made up of a circular patch slotted with three T-shaped, three PIN diodes as a switch, and a microstrip feed microstrip antenna. The suggested antenna can realize four radiation pattern modes, at the frequency of 2.4 GHz by varying the switching situations of the PIN (switch) diodes. The designed antenna's operational frequency range, meanwhile, ranges from 1.8 GHz to 10.7 GHz cover the complete ultra-wideband. The radiation beam of the designed antenna can direct in omnidirectional, bidirectional, unidirectional, broadside in the E and H plane providing a gain of approximately 3 dBi at 2.4 GHz. It would be an excellent option for a wireless communication system that can be used for Bluetooth, WLAN, Wi-Max, and 5G communication along with ultra-wideband and cognitive network applications.
