“…The implemented PECPA possesses a widened azimuth HPBW up to 150°, which is superior to all reported PECPAs using 1D electric dipoles. Therefore, the design approach is expected to get wide applications in future antenna-in-packages (AiPs) systems when combined with novel materials [21] and advanced fabrication processes [22]. Although the antennas exhibit narrow 3 dB ARBW, it is expected that the self-balanced concept [23] could be employed to suppress the cross-polarized components within the whole beamwidth, such that both HPBW and ARBW could be simultaneously broadened.…”

This letter proposes a novel planar endfire circularly polarized antenna with widened half‐power beamwidth. Widened azimuth beamwidth mechanism of 2D sectorial electric dipole is theoretically revealed, thus it is able to combine with a rectangular magnetic dipole to yield a half‐power beamwidth widened planar endfire circularly polarized antenna. Finally, a prototype planar endfire circularly polarized antenna with sectorial flared angle of α = 270° is fabricated, simulated, and implemented to validate the design approach. As investigated, the antenna exhibits broadened azimuth half‐power beamwidth of 150° over a frequency range of 2.40–2.45 GHz.
