Probes and related systems and methods are provided for locating markers implanted within a patient's body. The probe includes an antenna assembly adjacent a distal end thereof, the antenna assembly including a ceramic base including a flat distal surface and four proximal surfaces extending at an angle relative to a longitudinal axis of the probe to define a generally pyramid shape. The base includes antenna elements on the proximal surfaces, and radial slots between adjacent proximal surfaces to substantially isolate the antenna elements from each other. A controller is coupled to the antenna element for transmitting a signal into the patient's body and receiving a reflected signal reflected from a marker implanted within the patient's body to identify and/or locate the marker. 提供了用于定位植入患者身体内的标记物的探头和相关系统和方法。探头包括邻近其远端的天线组件，该天线组件包括陶瓷基部，该陶瓷基部包括平坦远侧表面、以及相对于探头的纵向轴线以一定角度延伸以限定大致金字塔形状的四个近侧表面。基部包括在近侧表面上的天线元件、以及在相邻近侧表面之间的径向槽以基本上将天线元件彼此隔离。控制器联接到天线元件，以用于将信号发射到患者身体内，并且接收从植入患者身体内的标记物反射的反射信号，以识别和/或定位标记物。
