A Dual-Band Printed End-Fire Antenna with DSPSL Feeding

الملخص EN

A novel dual-band printed end-fired antenna with double-sided parallel-strip line (DSPSL) feeding is presented.

The DSPSL acts in wideband transition using balanced transmission.

Two different modes of the parasitic patches allow the antenna to work in different bands.

The printed antenna is designed as a quasi-Yagi structure to achieve directivity in the lower band, and the parallel rectangular patches serve as the parasitic director.

These patches act as radiation patches with end-fire direction characteristics in the upper band.

The measured bandwidths were 18.3% for the lower frequency band (2.28–2.74 GHz) and 12.6% for the upper frequency band (5.46–6.2 GHz).
