Dual-Band Circularly Polarized Mobile Antenna for Millimeter-Wave Antenna Applications

Abstract

In this paper, a dual-band circularly polarized truncated corner microstrip antenna is simulated and fabricated to operate over millimeter wave frequencies for modern mobile applications. The propose antenna is designed as monolayer circularly polarized patch antenna fed by single-fed strip-line that has been taken to provide better resonating frequency. Further, this antenna has a high gain to resist the losses in millimeter band. Also, the truncated corners and the L-shaped slots in the proposed antenna have a big effect of the antenna performance. This proposed antenna is simulated by CST 2016. Also, the experimental results are measured by R&S®ZVA67 VNA (Vector Network Analyzer). Finally, the measured and simulated results are more closed to each other.
