Abstract

In this article, a lowprofile dual-polarized dielectric patch antenna (DPA) using TM101 and TM121 modes is proposed for achieving the impedance bandwidth (BW) enhancement. By introducing four metallic pins in a dielectric patch resonator (DPR), the TM121 mode is shifted to low frequencies while TM101 mode is shifted to high frequencies. Therefore, the two modes can be close to each other for obtaining wide working bandwidth. Moreover, two orthogonal aperture-coupled feeders are employed to excite the proposed DPR to realize the dual polarization. Finally, the proposed antenna is fabricated and measured. The simulated and measured results show that the 10 dB impedance matching bandwidth is 15.2% (5.05–5.87 GHz), while maintaining the low-profile characteristics with the height of 0.07λ0 (λ0 is free space wavelength at the center frequency f0). In addition, the antenna achieved a peak gain of 8.55 dBi in the operating frequency. © 2021 Wiley Periodicals LLC.
