N2 - This paper designs a novel fixed-beam series-fed microstrip antenna, which is applied to point-to-point wireless communication. To address the beam squint problem of traditional serial-fed traveling-wave antennas, this paper adopts the principle of non-Foster circuits and central feeding. The designed Non-Foster radiating elements possess negative group delay characteristics and can compensate for the dispersion of the microstrip transmission line, forming serial-fed elements with a flat transmission phase. Additionally, this work further forms a linear array through the center-fed method to achieve broadband broadside fixed-beam characteristics. To verify the principle, we have designed a linearly polarized fixed-beam antenna in the Kuband. The proposed antenna operates in the frequency range of 11.4 GHz to 12.7 GHz, with a return loss less than -10 dB, the beams constantly pointing in the broadside direction, a stable pencil beam shape, and a maximum realized gain of 16.85 dBi.
