Abstract

The proposed reconfigurable dual-band antenna switching between millimeter wave and sub-6 GHz bands is a necktie round shape patch design connected with a meandered radiating patch element at the top front with an H slot shape and a partial or truncated ground plane at the back to enhance the antenna's functionality and performance. The dual band antenna is designed using CST microwave studio on a substrate Rogers 3003 with a dimension of 27.8 mm x 14mm and thickness of 1.52 mm with a dielectric constant of 2.2 and a loss tangent of 0.0009 respectively. The PIN diode (SMP 1321-079LF) is placed between the two parts to resonate the antenna at 3.5 and 28 GHz by altering the switching state. During the ON state of the PIN diode, the antenna operates at both 3.5 GHz and 28 GHz; whereas, in the OFF state, it operates in the mm-wave band at 28 GHz, thereby eliminating the 3.5 GHz band. The proposed antenna has an ultra-wide bandwidth of 19.65 GHz covering almost all the milli meter wave bands of 23 GHz, 28 GHz, and 38 GHz (from 22.65 – 42.30 GHz) while the sub-6 GHz band has a bandwidth of 962 MHz (3.02 – 3.99 GHz) respectively. The return loss of the antenna is -31.33 dB and -49.72 dB at 3.5 GHz and 28 GHz respectively. However, this antenna is compact and combines two different frequency bands, the large frequency ratio between the millimeter wave band to the sub-6 GHz band is 8.
