LPRLSAA is defined as Linearly-Polarized Radial Line Slot-Array Antenna very rarely.

antenna. In [12], a HMSIW circularly polarized antenna based on leaky-wave principles was presented. In this paper, a half-mode substrate integrated wave-guide U-slot antenna radiating left-handed circularly po-larized wave is proposed. Its concept is simple and based on a linearly polarized HMSIW U-slot antenna [13]. The
