Single-Fed Low-Profile High-Gain Circularly Polarized Slotted Cavity Antenna Using a High-Order Mode

Abstract: In this letter, a single-fed low-profile high-gain circularly polarized slotted cavity antenna using a high-order cavity mode, i.e. TE 440 mode, is proposed. The proposed antenna has a simple structure which consists of a radiating linearly polarized slotted cavity antenna and a linear-to-circular polarization converter. An antenna prototype operating at WLAN 5.8 GHz band fabricated with low-cost standard printed circuit board (PCB) process is exemplified to validate the proposed concept. Measured results comp… Show more

“…For most dual bands antenna, the TM 11 is excited, but higher modes are needed to be excited by properly tuning the position of feeding point to form a multiband antenna. For an equilateral triangular path antenna, the lowest five operating modes are TM 10 , TM 11 , TM 22 , TM 12 , and TM 33 .…”

“…The reason is that resonant frequencies are decided by the sizes of the slot and SIW cavity. After parameter optimization, offset is chosen to 13.2 mm that results in four bands excited by TM 10 , TM 22 , TM 12 , and TM 33 .…”
