A　broadband　antenna　for　satellite　navigation　terminal　is　proposed.　The　antenna　is　composed　of　a　pair　of　cross　dipole　arms,　the　side　loaded　metal　strips　and　a　bottom　ground.　The　side　loaded　metal　strips　can　help　to　improve　the　axial　ratio　(AR)　bandwidth　and　impedance　bandwidth　of　the　antenna,　and　reduce　the　size　of　the　overall　antenna.　The　measured　results　show　that　the　impedance　bandwidth　of　|S11|≤　−10　dB　is　1.06−2.01　GHz,　AR　bandwidth　of　AR　≤　3　dB　is　1.11−1.95　GHz,　and　the　gains　at　the　center　frequency　of　BeiDou　B1,　B2　and　B3　are　4.62,　5.34　and　5.21　dBi,　respectively.　The　cross　dipole　antenna　proposed　in　this　paper　does　not　need　complex　feed　network,　and　has　the　advantages　of　simple　antenna　structure,　miniaturization　and　wide　band.　It　can　be　better　applied　in　BeiDou　satellite　navigation　terminal.　©　2023　Chinese　Research　Institute　of　Radiowave　Propagation.　All　rights　reserved.
