A Novel SWB Small Rhombic Microstrip Antenna with Parasitic Rectangle into Slot of the Feed LineAbstract
In this letter, a rhombic monopole antenna with a parasitic rectangle into slot of the feed line is proposed to broaden impedance bandwidth. The antenna has a compact size with 19 × 16mm2 which has been printed on a FR4 substrate with thickness of 1mm. The measurements show that the antenna has reflection coefficient better than -10dB from 2.9 up to 29GHz. Meanwhile, the measured patterns and gain are presented later in the paper.
